P1524 on 2018-2024 Dodge Durango 6.4L: Oil Pressure & VVT Fixes
On a Dodge Durango with the 6.4L Hemi, code P1524 almost always points to an issue with engine oil quality, level, or pressure. Before replacing any parts, check your oil level and perform an oil change. Use the correct full synthetic 0W-40 oil and a genuine OEM Mopar filter (Part No. MO-899 or 04892339AA). This simple and inexpensive step resolves the code in a majority of cases, as these engines are notoriously sensitive to filter quality.

Drivable, but...
— You can drive, but it's not recommended for extended periods. The engine has disabled key performance and efficiency systems for self-protection. If the cause is genuinely low oil pressure, continued driving risks severe internal engine damage, such as to the camshaft and lifters.
Key Takeaways
- P1524 means oil pressure is too low for the VVT/MDS system to work.
- The most likely fix is an oil change with the correct 0W-40 synthetic oil and a genuine Mopar oil filter.
- Do not immediately assume a major engine problem; always start with the simplest solution (oil and filter).
- If an oil change doesn't fix it, the next most likely culprit is a faulty oil pressure sensor.
- Never ignore this code, as it could be warning of a genuine low oil pressure condition that can destroy your engine.
The trouble code P1524 stands for "Oil Pressure Out Of Range - Camshaft Advance/Retard Disabled." This means the Powertrain Control Module (PCM) has detected that the engine's oil pressure has fallen below the minimum level required for the Variable Valve Timing (VVT) and Multi-Displacement System (MDS) to function safely. To prevent potential engine damage from insufficient lubrication, the PCM disables these systems, illuminates the Check Engine Light, and stores the P1524 code. On these engines, the VVT system often requires pressure to reach around 42 PSI to be enabled and will be disabled if it drops below a threshold of approximately 31-36 PSI.
What's Unique About the 2011-2024 Dodge Durango
The 6.4L Hemi engine, found in the Durango SRT models from 2018-2024, is highly sensitive to oil pressure and quality. Both the VVT and MDS systems depend on precise oil pressure delivered by specific oil passages to function. Many owners and even official manufacturer documents have confirmed that these engines are particularly intolerant of certain aftermarket oil filters. A TSB was even issued regarding certain Amsoil filters causing this code. Using incorrect or even some high-efficiency aftermarket filters can restrict oil flow, causing a pressure drop sufficient to trigger a P1524 code, even with fresh, correct-viscosity oil. Sticking with the OEM Mopar filter is the most widely recommended first step for this reason.
Generation note: The 2011-2024 Dodge Durango is the third generation (WD). However, the 6.4L Hemi V8 engine was introduced to the Durango lineup starting with the 2018 model year. This guide is specific to the 2018-2024 models equipped with this engine, though the same issue is common on other vehicles with the 6.4L Hemi.
Professional service recommended: While an oil change is a DIY task, if the code persists it indicates a potential oil pressure problem that could quickly lead to catastrophic engine damage if misdiagnosed. A professional can perform a mechanical oil pressure test to rule out a severe internal issue.
Symptoms You May Notice
- Check Engine Light is on
- Noticeable loss of engine performance or acceleration
- Rough or unstable idle
- Engine ticking or rattling noises, especially between 1500-2000 RPM
- Oil pressure gauge on the dashboard reading lower than normal (e.g., below 35-40 PSI at highway speeds, or below 25-30 PSI at hot idle).
- MDS (4-cylinder mode) will not activate
⚠️ Don't Waste Money on the Wrong Fix
- Replacing VVT or MDS solenoids. While these systems are disabled by the code, they are rarely the root cause. The problem is the oil pressure they rely on, not the solenoids themselves.
Most Likely Causes
- Incorrect, Low, or Dirty Engine Oil 🔴 High Probability The Hemi's VVT and MDS systems are highly sensitive to oil viscosity and cleanliness to function correctly. The wrong oil can aerate or fail to maintain pressure when hot.
How to confirm: Check the oil dipstick for level and inspect the oil's color and consistency. If it's low, dark, foamy, or sludgy, it needs to be changed.
Typical fix: Perform an oil and filter change using the manufacturer-specified oil type (full synthetic 0W-40 is specified for the 6.4L Hemi) and a high-quality OEM Mopar oil filter.
Est. part cost: $70-$130 - Incorrect or Clogged Oil Filter 🔴 High Probability These engines are known to be sensitive to oil filter quality. Low-quality or incorrect aftermarket filters can cause a pressure drop sufficient to trigger this code. A TSB specifically calls out certain AMSOIL filters as a potential cause.
How to confirm: Inspect the installed oil filter. If it is not a genuine Mopar filter (e.g., MO-899) or a reputable equivalent, it is highly suspect. Owners on forums report the code appearing immediately after an oil change at non-dealer shops using generic filters.
Typical fix: Replace the existing oil filter with a new, genuine Mopar oil filter (Part No. 04892339AA or MO-899). It is best to perform a full oil change at the same time.
Est. part cost: $15-$30 - Faulty Oil Pressure Sensor 🟡 Medium Probability The sensor, also called a transducer, can fail over time, sending incorrect readings to the PCM. Coolant leaks from the thermostat housing above can sometimes drip onto the sensor and its connector, causing it to fail prematurely.
How to confirm: Use a scan tool to monitor live oil pressure data. Compare this reading to a measurement from a mechanical oil pressure gauge connected to the engine. If the mechanical gauge shows good pressure (e.g., >40 PSI at 2000 RPM) but the scan tool reads low, the sensor is likely bad.
Typical fix: Replace the oil pressure sensor. On the 6.4L Hemi, it is located on the front of the engine, near the oil filter housing and underneath the alternator.
Est. part cost: $50-$95
Rare But Worth Checking
- Failing Oil Pump: If an oil and filter change and a new pressure sensor do not resolve the code, and a mechanical gauge confirms low pressure, the oil pump may be failing. This is a serious mechanical issue requiring significant labor to replace.
- Worn Camshaft and Lifters: In high-mileage or poorly maintained engines, wear in components like camshaft bearings or lifters can cause an internal oil pressure loss, leading to this code. This is often accompanied by other codes (like P030X misfire codes) and a distinct ticking noise known as the 'Hemi tick'.
- Wiring Harness Damage: Check the wiring and connector for the oil pressure sensor for any signs of damage, corrosion, or oil contamination. The connector can become brittle from heat cycles.
Diagnosis Steps
- Check the engine oil level and condition. Top off or perform a full oil change if needed. Use the correct oil viscosity (Pennzoil Ultra Platinum 0W-40 is often recommended) and a genuine OEM Mopar oil filter (MO-899).
- After the oil change, clear the code and drive the vehicle to see if it returns. Many owners report this is the complete fix.
- If the code returns, connect a scan tool and monitor the oil pressure reading (PID) while the engine is running. Note the pressure at hot idle (should be >25 PSI) and at 2,000-2,500 RPM (should be >42 PSI).
- To definitively test the sensor, install a mechanical oil pressure gauge in place of the electronic sensor. This is the most crucial diagnostic step.
- If the mechanical gauge shows healthy pressure while the scan tool shows low pressure, the oil pressure sensor is faulty and should be replaced.
- If the mechanical gauge confirms low oil pressure (matching the scan tool), the problem is more severe. It could be a failing oil pump, clogged oil passages, or excessive internal engine wear (cam bearings, lifters). This requires professional diagnosis and likely significant engine disassembly.
Parts You'll Likely Need
- Engine Oil and Filter
(OEM #04892339AA (also known as MO-339 or MO-899))— This is the most common and simplest fix. The 6.4L Hemi is sensitive to oil quality and filter type.
Trusted brands: Mopar (Filter), Pennzoil Ultra Platinum (Oil), Mobil 1 (Oil)
OEM price range: $75-$130
Aftermarket price range: $60-$110 - Engine Oil Pressure Sensor
(OEM #68334877AA)— This sensor is the second most likely cause if an oil change doesn't work. It provides the pressure reading that triggers the code.
Trusted brands: Mopar
OEM price range: $50-$95
Aftermarket price range: $30-$60
Related Codes That Often Appear With This One
- P0520 — This code specifically indicates a fault in the oil pressure sensor/switch circuit. If you see P1524 and P0520 together, it points more strongly toward a bad sensor or wiring issue.
- P0521 — This code indicates the Engine Oil Pressure Sensor/Switch is not performing within its expected range. It often appears with P1524 when the sensor is providing erratic but not completely failed readings.
- P06DD — This code is for 'Engine Oil Pressure Control Circuit Stuck Off'. It often appears with P1524 and points to a mechanical or hydraulic issue preventing the oil pump from building sufficient pressure, rather than just a sensor electrical fault.
Technical Service Bulletins (TSBs) & Recalls
- S2109000001: Notes that customers may complain of a MIL lamp and find fault code P1524. It advises technicians to check if the customer recently had an oil change and if an AMSOIL brand filter was installed, recommending replacement with a Mopar filter.
Platform-Specific Known Issues
- A Technical Service Bulletin (TSB #S2109000001) was issued acknowledging this fault code, specifically mentioning that a recent oil change with an AMSOIL brand filter could be the cause.
- Owners on forums frequently report that using non-OEM oil filters, especially budget brands like Fram or store brands like 'Carguard', is a direct cause of P1524.
- The oil pressure sensor is located under the alternator, and a coolant leak from the thermostat housing can drip onto it, causing premature failure.
Mechanic-Grade Diagnostic Values
- VVT/MDS Activation Oil Pressure Threshold — expected: Pressure must reach 42 PSI to enable the system and must not drop below 31 PSI during operation.. Failure: If pressure fails to reach 42 PSI or drops below 31 PSI, the PCM will log P1524 and disable the system.
- Normal Operating Oil Pressure (Hot) — expected: Idle: ~25-41 PSI. Highway Cruise (2000-2500 RPM): ~45-60 PSI.. Failure: Pressure dropping to ~26 PSI at idle and ~34 PSI at highway speeds has been shown to trigger the code.
- Oil Pressure Sensor Circuit Voltage Drop Test — expected: With ignition on (engine off), connect a jumper wire between the sensor ground circuit (K900) and the signal circuit (G6) at the sensor connector. The voltage on a scan tool should drop from approx. 5.0V to less than 0.1V.. Failure: If the voltage does not drop as expected, it indicates high resistance or an open in the signal or ground circuit.
Scan Tool Commands That Help
- wiTECH or equivalent professional scan tool: Live Data / Data Display -> Engine Oil Pressure — This is the first step to see what oil pressure the PCM is reporting. This value should be compared against a mechanical gauge reading to determine if the sensor is faulty or if there is a true pressure problem.
Wiring & Ground Locations
- (G6) Engine Oil Pressure Signal — This is the signal wire in the harness connector for the oil pressure sensor, running back to the Powertrain Control Module (PCM).. This circuit carries the pressure reading to the PCM. High resistance or a short on this wire will cause incorrect readings and trigger fault codes.
- (K900) Sensor Ground — This is the ground wire in the harness connector for the oil pressure sensor.. A poor ground connection will cause the sensor to read incorrectly, leading to false pressure readings and codes.
- Engine Ground Jumper (P/N 68349162AA) — A specific ground strap for the 6.4L Hemi engine block.. While not directly for the sensor, a poor main engine ground can cause a variety of sensor and module communication issues. Ensuring all engine grounds are clean and tight is a critical step in diagnosing any electronic fault.
Real Owner Repair Stories
- RamForum.com user report (Ram 1500 with Hemi engine (specifics analogous to Durango 6.4L)) — Check engine light with code P1524. Oil pressure was low: 26 PSI at idle and 34 PSI on the highway.
❌ Tried (didn't work) Replacing the oil pressure sensor.
✅ What actually fixed it Replacing the existing Wix 57060 oil filter with a different model from the same brand, a Wix 57060XP. Oil pressure immediately returned to normal (41 PSI idle, 55 PSI highway). This highlights extreme sensitivity to filter construction, not just brand. - YouTube channel 'Dan the Fix it Man' (2016 Ram 1500 5.7L Hemi) — Check engine light with P1524, accompanied by a strange rattling/vibration noise between 1500-2000 RPM.
❌ Tried (didn't work) Replacing the oil pressure sensor., Replacing the PCV valve.
✅ What actually fixed it The problem started after an oil change using Amsoil oil and a new brand of filter. The fix was changing the oil back to the previously used Valvoline Full Synthetic and a Mobil 1 oil filter. This resolved the code and the noise.
OEM Part Supersession History
68334877AA→68334877AA (current)— No supersession found.
Heads up: Part number appears to be stable for the specified model years. It is crucial to use the OEM sensor, as aftermarket versions are frequently reported to fail or read inaccurately.
Model Year Variations Within This Range
- 2018-2024: While not specific to the Durango, a known change on Hemi platforms (like the Ram 1500) around 2013 involved a switch to a smaller oil filter (like Mopar MO-339) to accommodate electronic power steering components. However, the engine block's filter mount remained the same. This allows the use of the larger, older-style filter (Mopar MO-899 / Wix 57060) which has the same gasket diameter but offers more filter media. Some owners prefer using the larger filter.
Diagnostic Flowchart
P1524 indicates 'Oil Pressure Out of Range - Camshaft VVT Under Temperature'. Because the 6.4L Hemi relies on precise oil pressure for VVT and MDS, start by verifying the oiling system integrity before assuming a mechanical failure.
→ Perform a full oil change using 7 quarts of Pennzoil Ultra Platinum 0W-40 and a genuine Mopar MO-899 filter (Part No. 04892339AA). Per TSB #S2109000001, aftermarket filters often cause this specific code. Clear codes and test drive.
Connect a scan tool and monitor Oil Pressure PIDs. At hot idle, is pressure below 25 PSI, or below 42 PSI at 2,000 RPM?
Install a mechanical oil pressure gauge at the sensor port. Does the mechanical gauge confirm the low pressure seen on the scan tool?
→ The Oil Pressure Sensor (transducer) is faulty. Replace with a Mopar unit ($50-$95). The discrepancy between the mechanical reading and the PCM reading is the root cause.
Listen to the engine between 1500-2000 RPM. Do you hear a distinct ticking or rattling noise?
Is the 'Hemi Tick' present at the top of the engine or near the exhaust manifolds?
→ Check for broken rear exhaust manifold bolts. While this causes a tick, it won't cause P1524. If P1524 persists with low pressure, proceed to internal engine inspection.
→ Severe internal wear detected. Low pressure combined with P1524 and ticking often indicates failed lifters or cam bearings. Significant engine disassembly is required to inspect the camshaft and MDS solenoids.
→ Inspect the oil pump and pickup tube. A restricted pickup screen or a failing high-volume oil pump (common on high-mileage 392 Hemis) is likely failing to provide the volume required for VVT/MDS operation.
→ The PCM is likely receiving intermittent bad data. Inspect the Oil Pressure Sensor connector for coolant contamination from a leaking thermostat housing (a common 6.4L quirk). If clean, replace the sensor located under the alternator.
Other Known Issues on This Vehicle
Issues unrelated to this code that are worth knowing about as an owner of this generation:
- Hydraulic Lifter / Camshaft Failure ('Hemi Tick') 🔴 High — Common on engines over 70,000 miles, especially those with extended idle time or infrequent oil changes. Failures are seen on engines approaching and exceeding 100,000 miles.
- Broken Exhaust Manifold Bolts 🟠 Medium — A ticking noise, especially on cold starts, is a common symptom. The rear-most bolts are most prone to breaking due to thermal stress. This is a very common issue across Hemi-powered Dodge vehicles.
- Leaking/Failing Center Tail Light Assembly ('Racetrack') 🟡 Low — Extremely common. The seal around the tail light assembly fails, allowing water intrusion which shorts out the LEDs, causing sections to go dim or fail completely.
- Electronic Stability Control (ESC) / Throttle Control Faults 🟠 Medium — Owners report occasional instances where the ESC light illuminates and the vehicle enters a limp mode with reduced throttle response. Cleaning the throttle body and ensuring the TPS sensor connection is secure can sometimes resolve it.
- A/C System Hissing / Failure 🟠 Medium — A noticeable hissing sound from the dashboard and eventual loss of cooling is reported by many owners, often pointing to issues with the A/C condenser or compressor.
Used vs. New Parts: Buying Guide for This Vehicle
When a used part is the smart pick: For repairs related to code P1524, using used parts is strongly discouraged. The most common fixes involve consumable items (oil, filter) and a sensitive electronic sensor that is inexpensive to buy new.
OEM-only on this vehicle (don't cheap out):
- Engine Oil Filter: This is the most critical component. Use only a genuine Mopar filter (MO-899 or equivalent) to guarantee correct flow and pressure characteristics. Aftermarket filters, even from reputable brands, are the number one cause of this code.
- Engine Oil Pressure Sensor: While some aftermarket sensors may work, many owners report immediate or premature failure. Using a genuine Mopar sensor (68334877AA) is the safest choice to avoid repeat repairs.
Brands owners have reported issues with on this vehicle:
- Amsoil (Filters): A TSB specifically mentions this brand's filters as a potential cause.
- Carguard (Filters): Forum users have specifically named this store brand as causing P1524.
- Fram (Filters): Frequently cited by Hemi owners as a brand to avoid for oil filters.
- Generic/Store Brand Filters: Any low-cost, generic filter is highly suspect and should be avoided.

Frequently Asked Questions
I just had my oil changed at a quick-lube shop and now P1524 is on. Could the filter be the problem?
Yes. The 6.4L Hemi is highly sensitive to oil filter quality. TSB #S2109000001 specifically notes that non-OEM filters, including AMSOIL or budget brands like 'Carguard' or 'Prompto', can trigger this code. Replacing it with a genuine Mopar filter (MO-899) often resolves the issue.
What specific oil should I be using in my 2011-2024 Durango 6.4L to avoid P1524?
The manufacturer specifies full synthetic 0W-40 oil for the 6.4L Hemi. Pennzoil Ultra Platinum 0W-40 is frequently recommended to ensure the VVT and MDS systems maintain proper pressure.
My oil pressure gauge shows 30 PSI at highway speeds. Is this normal for the 392 Hemi?
No, that is lower than normal. Expected readings for this engine should be above 35-40 PSI at highway speeds and at least 25-30 PSI at a hot idle. Lower readings may trigger the P1524 code.
Can a coolant leak cause a P1524 oil pressure code on my Durango?
Yes. On the 6.4L Hemi, the oil pressure sensor is located under the alternator. A leak from the thermostat housing directly above can drip onto the sensor or its connector, leading to premature failure and incorrect pressure readings.
Why won't my Durango go into 4-cylinder (MDS) mode when P1524 is active?
The MDS system relies on precise oil pressure to deactivate cylinders. When the PCM detects oil pressure that is too low or out of spec (P1524), it disables MDS as a fail-safe.
Is there a specific Mopar part number for the oil filter I should use?
Yes, the recommended genuine Mopar oil filter part numbers are 04892339AA or MO-899.
