OBD-II Code P0013: Exhaust Camshaft Position Actuator Circuit Malfunction

What Does P0013 Mean?

The Engine Control Module (ECM) detected an electrical problem with the exhaust camshaft's oil control valve (VVT solenoid). This valve adjusts engine timing to improve performance. P0013 specifically points to a circuit failure for the 'B' (exhaust) camshaft on Bank 1.

Technical definition: The SAE/OBD-II definition is "'B' Camshaft Position - Actuator Circuit/Open (Bank 1)". The ECM triggers this code when it commands the exhaust VVT solenoid to change camshaft position, but the electrical circuit's voltage or resistance does not match 🎬 See how to diagnose and fix an open actuator circuit. expected values for more than a few seconds.

Can I Drive With P0013?

Yes, But With Caution. Yes, but limit driving to short distances. Prolonged driving causes misfires that damage the catalytic converter (an $800-$2500+ repair) or leads to internal engine damage from incorrect timing, potentially resulting in complete engine failure.

Common Causes

• Low, Dirty, or Incorrect Viscosity Engine Oil (Very Common) — The VVT system relies on clean oil at precise pressures. Old, sludgy, or incorrect viscosity oil clogs the solenoid's microscopic screens, causing immediate malfunction.
• Faulty Exhaust Camshaft VVT Solenoid (Very Common) — The solenoid's internal electromagnetic coil burns out, shorts, or sticks mechanically. Cheap aftermarket replacements also fail prematurely, causing returning codes.
• Damaged Wiring or Corroded Electrical Connector (Common) — Engine heat and vibration fray the solenoid's wiring harness. Oil intrusion or water corrodes the connector pins, creating high resistance or an open circuit.
• Clogged Camshaft Phaser / Actuator (Less Common) — Sludge blocks the camshaft phaser. Even with a perfectly functioning solenoid, a clogged phaser cannot adjust timing, prompting the ECM to flag a circuit or performance error.
• Stretched Timing Chain or Failed Tensioner (Less Common) — A stretched timing chain pushes the camshaft's baseline position so far out of specification that the ECM registers a fault with the control system.
• Clogged VVT Solenoid Banjo Bolt Filter (Rare) — Specific engines (like Subarus) use a tiny mesh filter inside the oil supply line's banjo bolt. Debris clogs this screen, starving the solenoid of oil pressure.
• Faulty Engine Control Module (ECM) (Rare) — The ECM's internal driver circuit that grounds the solenoid fails. Rule out all wiring and solenoid issues before condemning the ECM.

Symptoms

• Check Engine Light is On — Illuminates immediately when the ECM logs the P0013 fault.
• Rough Idle and Stalling — Incorrect exhaust valve timing disrupts combustion, causing the engine to shake at idle or stall at stops.
• Reduced Engine Power and Hesitation — The vehicle feels sluggish and hesitates during acceleration because the engine cannot advance timing for optimal power.
• Poor Fuel Economy — Inefficient combustion drops fuel efficiency by 10-20%.
• Hard Starting — A camshaft stuck in an advanced or retarded position makes the engine crank longer before starting.
• Rattling Noise from Engine — A brief metallic rattle on cold starts indicates low oil pressure reaching the VVT phasers or timing chain tensioner.

Used vs. New Parts: Buying Guide

When a used part is worth it: Buying a used VVT solenoid is never recommended. The part is inexpensive new, is a known wear item, and the labor to replace a failed used part negates any initial savings.

Donor-vehicle mileage cap: roughly under 30000 miles for the part to have meaningful remaining life.

Donor quality checklist:

• Verify the donor vehicle was not scrapped for engine-related issues.
• Match the OEM part number exactly; connectors and internal specs vary.
• Avoid parts showing signs of oil sludge or heavy corrosion.

Decision logic:

• If The part is under $100 new (OEM or high-quality aftermarket) → Always buy new. The risk of premature failure with a used part is too high.
• If The vehicle is old and budget is the absolute primary concern → A used part is a gamble, but provides a temporary fix. Expect a significantly shorter lifespan.
• If OEM part is on backorder and a high-quality aftermarket version is unavailable → A used OEM part is a better choice than a low-quality new aftermarket part.

Warranty tradeoff: Used parts typically offer a 30-90 day warranty for part replacement only (not labor). New aftermarket parts usually have a 1-year to lifetime warranty. New OEM parts carry a 1-2 year warranty.

Worst-case if a used part fails: $100-$250 if a used solenoid fails shortly after installation, requiring repeat labor costs plus the cost of another part.

What Happens If You Wait — Timeline

1. 0-1 month: Check Engine Light is on. You notice a slightly rough idle and a small drop in fuel economy. Symptoms are intermittent. (MPG impact: 3-7%% · Added cost: $0-50 in wasted fuel.)
2. 1-3 months: Engine performance noticeably declines. Hesitation during acceleration becomes frequent, and the rough idle is constant. Fuel economy loss is significant. (MPG impact: 7-15%% · Added cost: $50-150 in wasted fuel.)
3. 3-6 months: The engine runs poorly, stalls at stops, and has difficulty starting. Inefficient combustion from incorrect timing overloads the catalytic converter with unburnt fuel, risking severe damage. (MPG impact: 15-20%% · Added cost: $950-$2,500 if the catalytic converter is damaged.)
4. 6+ months: If the root cause is oil pressure or a timing chain, continued operation risks severe internal engine damage. This includes a jumped timing chain, leading to piston-to-valve contact and catastrophic engine failure. (MPG impact: >20%% · Added cost: $3,000-$8,000+ for major engine repair or replacement.)

Cost of Not Fixing It

• 0-1 month: Noticeable drop in fuel economy (5-15%), rough idle, and poor acceleration. Failed emissions test. (Added cost: Negligible, other than increased fuel cost.)
• 1-6 months: Continued misfires and inefficient combustion overheat the catalytic converter, causing it to fail due to unburnt fuel saturation. (Added cost: $950-$2,500 for catalytic converter replacement.)
• 6+ months: If the issue relates to oil pressure or a timing chain, ignoring it leads to catastrophic engine damage (jumped timing, piston-to-valve contact), requiring a complete engine rebuild. (Added cost: $3,000-$8,000+)

Diagnosis Steps

1. Check Engine Oil Level and Condition
   Pull the dipstick to check if the oil level is within the proper range. Note the color and consistency; if it is black, thick, or sludgy, change it immediately. This is the primary cause of VVT faults.
   Tools: Rag or paper towel (Beginner)
2. Inspect the Solenoid's Electrical Connector and Wiring
   Locate the exhaust camshaft position actuator solenoid (usually on top of the valve cover). Unplug the electrical connector and inspect it for corrosion, bent pins, or oil contamination. Follow the wiring harness back, looking for breaks, fraying, or heat damage.
   Tools: Flashlight (Beginner)
3. Test the Solenoid's Internal Resistance
   With the solenoid unplugged, set your multimeter to Ohms (Ω). Measure the electrical resistance between the solenoid's two pins. A reading of 'OL' (Over Limit) means an open circuit, while a reading near zero indicates a short. Common specs are 8-15 ohms. If outside this range, the solenoid is bad.
   Tools: Multimeter (Intermediate)
4. Test for Power at the Connector
   Turn the ignition key to the 'On' position (engine off). Use a multimeter set to DC Volts. Connect the black lead to a good ground and probe both terminals in the harness connector with the red lead. One pin must show battery voltage (11V-12.5V). If there is no voltage, trace a break in the power supply wire or check for a blown fuse.
   Tools: Multimeter (Intermediate)
5. Check Live Data with a Scan Tool
   Connect a scan tool and monitor the PIDs for 'Desired Camshaft Position' vs. 'Actual Camshaft Position'. At idle, these values sit near 0 degrees. As you raise the engine RPM to 2000-3000, the ECM commands a change. If the desired value changes but the actual value does not, it points to a mechanical solenoid failure, oil flow issue, or clogged phaser.
   Tools: OBD-II Scan Tool (with live data) (Advanced)
6. Command the Solenoid with a Bi-Directional Scan Tool
   Using a bi-directional scan tool, directly command the solenoid's duty cycle to 25% while idling. Activating the solenoid forces the timing out of position, causing a rougher idle and an audible click. If the engine stumbles, the solenoid and phaser work mechanically. If nothing happens, the solenoid is stuck or clogged.
   Tools: Bi-directional scan tool (Advanced)
7. Check the Solenoid Control Circuit (Duty Cycle)
   With the solenoid unplugged and the key on, connect a test light to battery positive. Probe the control wire (the ground wire) at the harness connector. The test light illuminates when the ECM provides a ground path. For precise testing, use an oscilloscope to view the duty cycle square wave from the ECM while the engine runs.
   Tools: Test light, Oscilloscope (optional) (Advanced)
8. Check Engine Oil Pressure
   Connect a mechanical oil pressure gauge. At a hot idle, engines require at least 20-25 PSI. At 3,000 RPM, it climbs to 45-70 PSI. Low pressure prevents the phaser from operating correctly and indicates worn oil pumps or bearings.
   Tools: Mechanical oil pressure gauge (Advanced)
9. Check for a Stretched Timing Chain
   Remove the valve cover to inspect the timing chain for excessive slack. If the chain is loose or the tensioner failed, it must be replaced. Stop DIY diagnosis here and consult a professional engine builder.
   Tools: Extensive mechanic's tool set (Professional)

When This Code Triggers (Freeze-Frame Conditions)

• Engine Coolant Temp: 185-210°F (Engine at full operating temperature.)
• RPM: 1500-3000 RPM (During acceleration or steady cruise when the ECM commands a change in cam timing.)
• Engine Load: 25-75% (The fault triggers under moderate load, not at idle or full throttle.)
• Fault Trigger Time: > 5 seconds (The code sets when the detected circuit fault (open/short) persists for several seconds.)

Related Codes

• P0014 — P0013 indicates an electrical circuit fault, while P0014 indicates a mechanical timing performance issue ('Over-Advanced'). The electrical fault (P0013) causes the timing to stick, triggering P0014. Always fix P0013 first.
• P0010 — The identical circuit malfunction code for the 'A' (intake) camshaft on Bank 1. If both appear together, suspect severely dirty oil, low oil pressure, or a shared power/ground wire issue in the harness.
• P0011 — The 'over-advanced' code for the 'A' (intake) camshaft. Seeing it with P0013 suggests a wider timing system issue related to oil pressure or a timing chain problem affecting the entire Bank 1.
• P0023 — The identical code to P0013 but for Bank 2 of the engine (on V6 or V8 engines). The diagnostic process is exactly the same.

Climate & Environmental Factors

• Cold Weather: Extremely cold temperatures cause engine oil to thicken significantly, especially if the wrong viscosity is used. This leads to slow or no response from the VVT system on startup, triggering P0013 until the engine warms up.
• High Humidity / Salt: In humid or coastal climates, electrical connectors and wiring are highly susceptible to corrosion. A corroded connector creates high resistance or an open circuit, directly causing a P0013 code.

How to Talk to a Mechanic About This Code

Say this: "I have an OBD-II code P0013 for the exhaust camshaft actuator circuit. I've already checked the oil level and condition, and it's fine. I'd like to book a diagnostic appointment. Can you please start by testing the VVT solenoid's resistance and checking for power and ground at the connector?"

This signals you are an informed customer. It directs the mechanic to the most likely causes first, preventing them from charging you for simple checks you've already done. It focuses the diagnostic process and reduces the chance of being sold unnecessary services.

Avoid saying:

• 'My check engine light is on, can you look at it?'
• 'The car is running rough, I think it's the spark plugs.'
• 'Just fix whatever is wrong, I trust your judgment.'

Questions to ask before authorizing the repair:

• What was the resistance reading on the solenoid? Was it within the manufacturer's spec?
• Did you confirm there is battery voltage at the solenoid's connector with the key on?
• If you are recommending a new solenoid, is it an OEM part or aftermarket? What is the warranty on the part and the labor?
• If the solenoid and wiring are good, what is your next diagnostic step and what will it cost?

Where to Take It: Dealer vs Independent vs Chain

• Dealer: A safe but expensive choice. Best if other shops are stumped or if the vehicle is under warranty.
  Best for: Vehicles still under powertrain warranty., Complex diagnoses involving manufacturer-specific quirks (e.g., Subaru banjo bolt filters, Ford valve cover removal)., When you want to guarantee an OEM part is used.
  Downsides: Highest labor rates, typically 1.5-2x more than an independent shop., May recommend replacing related parts (e.g., both solenoids) as a policy, increasing cost. (Typical cost: +50% vs. baseline)
• Independent Shop: Best fit for most situations. A competent independent mechanic handles a P0013 diagnosis and repair efficiently and affordably.
  Best for: Out-of-warranty vehicles where cost is a factor., Most common P0013 scenarios (bad solenoid, oil change, simple wiring issue)., Building a long-term relationship with a trusted mechanic.
  Downsides: Quality and diagnostic capabilities vary widely. Vet shops by looking for ASE certifications and positive reviews., May not have experience with very new models or rare manufacturer-specific issues. (Typical cost: +0% vs. baseline)
• Chain Shop: Use with caution. Acceptable for a simple oil change, but AVOID for diagnosing a persistent P0013 code. The risk of misdiagnosis or being sold unnecessary parts is high.
  Best for: A simple oil and filter change if that is the suspected cause.
  Downsides: High pressure to upsell services (e.g., unnecessary engine flushes)., Technician skill and diagnostic ability are inconsistent., Often not equipped for in-depth electrical or timing chain diagnostics. (Typical cost: -10% vs. baseline)

When to Walk Away From the Repair

If the estimated repair cost exceeds 40-50% of the car's private-party value, seriously consider selling or trading it in instead of repairing it.

• Car worth $5000, fix is $250: Fix it. A solenoid replacement is a minor cost relative to the car's value.
• Car worth $4000, fix is $2200: Walk away. A timing chain replacement on a car of this value is a poor investment. The repair cost is over 50% of the car's worth.
• Car worth $8000, fix is $2200: Borderline. The repair is less than 30% of the car's value. Get a second opinion and consider the car's overall condition before proceeding.

What Scan Tool You Need for This Code

Minimum: A scanner that reads live data PIDs for camshaft position (Desired vs. Actual). A basic code reader that only shows the code number is not sufficient for a proper diagnosis.

A $20 code reader only tells you the P0013 code is present. It won't let you see if the ECM is commanding a change or if the camshaft is responding, which is crucial for distinguishing a bad solenoid from a clogged phaser or wiring issue.

Budget: BlueDriver Pro (~$100) — Connects to your smartphone via Bluetooth. It allows you to read the code, view freeze-frame data, and graph live data for the desired vs. actual camshaft positions. This is the minimum needed for a confident DIY diagnosis.

Mid-range: Foxwell NT510 Elite (~$160) — In addition to live data, this handheld tool offers bidirectional control. This allows you to manually command the VVT solenoid on and off from the scan tool to see if it clicks and if the engine stumbles. This is a definitive test for whether the solenoid works mechanically and electrically.

Professional: Autel MaxiCOM MK808 / MK808BT (~$500) — Provides full bidirectional control, advanced live data graphing, and access to all vehicle modules. This professional-grade tool is overkill for just one code but is a great investment for serious DIYers who work on multiple cars.

How to Clear the Code After You Fix It

1. Use an OBD-II scan tool to clear the diagnostic trouble code.
2. Perform a complete drive cycle to allow readiness monitors to run.
3. Disconnecting the battery for 15+ minutes clears the code but resets all vehicle electronics and readiness monitors.

Drive cycle (~20 minutes): A general drive cycle includes: 1) Cold start and idle for 2-3 minutes. 2) Drive at a steady speed of 55-65 mph for 10-15 minutes. 3) Perform a few decelerations without braking (coasting). 4) Idle for another 2-3 minutes. This forces the Catalyst, O2, and EVAP monitors to run.

Readiness monitors affected: Comprehensive Component Monitor, Catalyst Monitor, EVAP System Monitor

Before emissions retest: drive at least 50 miles to fully set monitors.

Watch out for:

• Not completing the full drive cycle prevents readiness monitors from setting, causing an automatic emissions test failure.
• Clearing the code without fixing the underlying issue causes the code to return almost immediately.
• Simply disconnecting the battery does not guarantee all permanent codes clear on modern vehicles.

Will This Fail Emissions / State Inspection?

Yes — this code typically fails an OBD-II emissions inspection.

• California: An active P0013 code results in an automatic smog check failure. All readiness monitors must be 'Ready' before re-testing, requiring 50-100 miles of driving after the repair.
• New York: The NYS DMV inspection includes an OBD-II scan. An illuminated Check Engine Light from a P0013 code is an automatic failure.
• Texas: In counties requiring emissions testing, a P0013 code causes the vehicle to fail the OBD-II portion of the state inspection.

Most Commonly Affected Vehicles

• Chevrolet / GMC Equinox, Terrain, Malibu, Cobalt, HHR (2006-2017) — Extremely common on 2.4L Ecotec engines, often related to high oil consumption leading to low oil levels. Ensure you purchase the latest updated part numbers for the solenoids.
• Ford Focus, Fusion, Escape (2012-2018) — Common on 2.0L and 2.5L engines. On some 2.0L EcoBoost engines, the solenoids sit underneath the valve cover, turning a 15-minute job into a 2-3 hour repair.
• Hyundai / Kia Santa Fe, Sonata, Optima, Sorento, Sportage (2007-2018) — The 2.4L GDI engines are highly susceptible to sludge buildup from extended oil change intervals, which destroys the Oil Control Valve (OCV).
• Toyota Camry, RAV4, Highlander (2005-2016) — Common on 2GR-FE V6 and other VVT-i engines. The issue is usually a failed OCV or a clogged filter screen for the valve.
• Subaru Forester, Outback, Impreza (2011-2018) — On Subaru's AVCS system, always inspect the small mesh filter located inside the oil supply line's banjo bolt during diagnosis per TSB 02-163-16R.
• Chrysler / Dodge 200, Avenger, Journey (2011-2014) — Affects models with the 2.4L 'World Engine'. The solenoids are located on the front of the engine and are very easy to access and replace.
• Honda Civic, Accord, CR-V (2006-2021) — A known issue for 2016-2021 Civics. The solenoid resistance must measure between 6.9-7.9 ohms to function correctly.
• Buick Verano, Regal, LaCrosse (2011-2017) — Frequently paired with P0014 on the 2.4L engine. A faulty exhaust solenoid often reads in the thousands of ohms (kΩ) instead of the normal 10-15 ohms.

Manufacturer-Specific Notes

• General Motors (Chevrolet, GMC, Buick): On 2.4L Ecotec engines, replace both the intake and exhaust VVT solenoids at the same time, as the other is guaranteed to fail soon. Use only OEM or high-quality aftermarket parts, as these engines reject cheap solenoids.
• Ford: On 2.0L EcoBoost engines, the VVT solenoids are located underneath the valve cover. This requires replacing the valve cover gasket and significantly increases labor costs compared to externally accessible solenoids.
• Subaru: Per TSB 02-163-16R, it is critical to inspect the small mesh filter located inside the oil supply line banjo bolt for the OCV. A clog in this tiny filter starves the system of oil and perfectly mimics a failed solenoid.
• Hyundai / Kia: Many 2.0L and 2.4L GDI engines suffer from severe engine bearing wear caused by underlying oiling problems and sludge. These exact same sludge issues are the primary killers of the VVT solenoids on these models.

Real Owner Stories

2016 Chevy Equinox 2.4L - The Simple Fix

Check engine light came on intermittently for a week. Scan at an auto parts store revealed code P0013.

What they tried:

1. Replaced the exhaust VVT solenoid.

Outcome: The check engine light did not turn off immediately. After a day or two of normal driving (a few start/stop cycles), the code cleared itself and did not return.

Lesson: After a repair, the check engine light does not clear instantly. The system needs to complete a few drive cycles to verify the fix before turning the light off. You can also clear it manually with a scan tool.

2013 Chevy Equinox 2.4L - A Persistent Problem

Owner noticed poor acceleration, rough idle, and bad gas mileage for months. The car eventually stalled and threw code P0010 (Intake VVT circuit).

What they tried:

1. Replaced spark plugs, air filter, and performed an oil change, with no improvement.
2. Replaced both intake and exhaust VVT solenoids, which fixed the symptoms and cleared the P0010 code for about 300 miles.

Outcome: The symptoms returned, and the check engine light came back on, this time with code P0013. The issue was no longer the solenoid itself but a deeper problem with wiring or oil pressure.

Lesson: If replacing the VVT solenoid only provides a temporary fix, the root cause lies elsewhere in the system. Investigate the wiring harness for damage and check engine oil pressure before replacing more parts.

Subaru with AVCS - The Hidden Filter

A Subaru owner experienced P0013 and other VVT-related codes. Replacing the oil control valve (solenoid) did not resolve the issue.

What they tried:

1. Replaced the OCV/VVT solenoid.
2. Checked oil level and condition.

Outcome: A mechanic inspected the oil supply line banjo bolt for the VVT system. The tiny mesh filter inside the bolt was completely clogged with engine sludge. Cleaning this filter restored proper oil flow and permanently fixed the code.

Lesson: On certain makes like Subaru, always check for hidden inline oil filters (like those in banjo bolts) as specified in technical service bulletins. A clogged filter starves the VVT system of oil, perfectly mimicking a failed solenoid.

How to Prevent This Code From Triggering

• Perform regular oil and filter changes. (Every 5,000-7,500 miles, or as per manufacturer schedule.) — This is the single most effective preventative measure. It prevents the formation of engine sludge, which is the primary cause of clogged VVT solenoid screens and oil passages.
• Use the correct, high-quality engine oil. (Every oil change.) — Using the exact oil viscosity (e.g., 5W-30) recommended by the manufacturer is critical. The VVT system is hydraulic and calibrated to a specific oil weight. Incorrect viscosity causes pressure and flow issues.
• Consider a professional engine flush service. (Once every 50,000-60,000 miles, especially on GDI engines.) — Modern chemical flushes dissolve sludge and varnish in the tiny VVT oil passages without dislodging large chunks, keeping the solenoids and phasers clean and functional.
• Annually inspect VVT solenoid connectors. (Once per year or during other maintenance.) — Engine heat and vibration damage wiring over time. A quick visual inspection for frayed wires or corrosion at the connector, and applying dielectric grease, prevents future circuit fault codes.

Frequently Asked Questions

What is a common misdiagnosis for P0013?

A common mistake is confusing the VVT Solenoid (oil control valve) with the Camshaft Position Sensor. P0013 refers to the solenoid actuator circuit, so replacing the sensor will not fix it. Always check engine oil level and condition before replacing any parts.

I replaced the solenoid but the code came back. What now?

If a new solenoid doesn't fix the code, re-check the wiring harness for hidden breaks or corrosion. Ensure you used an OEM part, as cheap aftermarket solenoids frequently fail out of the box. If electricals are perfect, suspect a clogged oil passage or failed camshaft phaser.

What does 'Bank 1' and 'B Camshaft' mean?

'Bank 1' refers to the side of the engine containing cylinder #1, which is the only bank on an inline 4-cylinder engine. 'B' camshaft designates the exhaust camshaft. 'A' refers to the intake camshaft.

Can I just clean the VVT solenoid instead of replacing it?

Cleaning the solenoid's screens with brake cleaner sometimes provides a temporary fix if it is clogged with sludge. However, P0013 usually indicates an internal electrical failure (open or shorted coil) within the sealed unit. Since solenoids are inexpensive, replacement is the most reliable long-term solution.

Will an oil change fix a P0013 code?

If the code is triggered by low, old, or incorrect viscosity engine oil, an oil and filter change resolves the issue. The VVT system relies on precise hydraulic pressure to function. If the code returns after fresh oil is added, the solenoid or its circuit is faulty.

How can I prevent the P0013 code from coming back?

The best prevention is performing oil changes every 5,000 miles using high-quality, manufacturer-specified synthetic oil. This prevents the sludge buildup that clogs VVT solenoid screens and oil passages. Additionally, inspect the solenoid wiring connectors annually for oil intrusion or corrosion.

Is the VVT solenoid the same as the camshaft position sensor?

No, they are completely different components. The VVT solenoid is an actuator that controls oil flow to adjust camshaft timing. The camshaft position sensor simply monitors the camshaft's position and reports it to the ECM.

What is the cost to fix P0013?

An oil change costs $50-$100 and fixes many sludge-related P0013 codes. Replacing the VVT solenoid, the most common mechanical fix, typically costs $130-$300 for parts and labor. Severe issues like a stretched timing chain or damaged wiring harness exceed $1,000.

Key Takeaways

• Check your engine oil first; low or sludgy oil causes a large percentage of P0013 codes and requires a simple $50-$100 oil change to fix.
• Test the exhaust VVT solenoid's resistance with a multimeter; a reading outside the typical 8-15 Ohm range confirms an internal electrical failure.
• Replace both the intake and exhaust VVT solenoids simultaneously if one fails, as the second unit typically fails shortly after.
• Limit driving to under 50 miles with an active P0013 code to prevent unburnt fuel from destroying your catalytic converter, an $800 to $2,500 repair.
