P0017 on 2009-2011 Chevrolet Aveo: Crank-Cam Correlation Causes and Fixes

What's Unique About the 2009-2011 Chevrolet AVEO

The 1.6L engine in the 2009-2011 Aveo uses a timing belt, not a chain. While belt stretch or slippage is a common cause for this code on many cars, these specific GM engines have a known issue documented in Technical Service Bulletin PIP4543D. A small, black plastic oil sleeve between the camshaft and the camshaft actuator (phaser) can get lost or damaged during repairs. This sleeve is critical for directing oil to the actuator; without it, the ECM cannot control cam timing, leading directly to P0017 and related codes. This part is often overlooked by technicians and is not sold separately from the camshaft actuator assembly, making it a unique and frustrating problem for this platform.

Diagnostic Flowchart

Tap your situation to follow the diagnostic path that matches what you're seeing on this vehicle.

Symptoms You May Notice

• Check Engine Light is on
• Rough or uneven idle, sometimes fluctuating between 400-2000 RPMs before stalling.
• Engine stalling, especially at low speeds or when put into gear.
• Reduced engine power and poor acceleration.
• Difficulty starting the engine, or extended cranking time.
• Rattling noises from the engine.
• Increased fuel consumption.
• Hard, jolting deceleration for a split second while driving at highway speeds.

Most Likely Causes

1. Worn or Stretched Timing Belt 🔴 High Probability The 1.6L engine is an interference design with a timing belt that has a finite service life (typically 60,000 miles). Over time, the belt can stretch or jump a tooth, causing the cam and crank to go out of sync. A bad tensioner can also cause slack and lead to a jumped tooth.
   How to confirm: Visually inspect the timing belt for wear, damage, or slack. The definitive check is to verify the mechanical timing by aligning the crankshaft and camshaft timing marks. This requires specialized locking tools for accuracy on this engine.
   Typical fix: Replace the timing belt, tensioner, and idler pulleys. 🎬 Watch: Step-by-step timing belt replacement for the 1.6L Aveo engine. This is always done as a kit. It is critical that the timing marks are perfectly aligned upon reassembly.
   Est. part cost: $50-$150
2. Faulty Camshaft Position Actuator Solenoid (VVT Solenoid) 🔴 High Probability These solenoids control oil flow to the cam phasers. They can become clogged with dirty oil or fail electrically, preventing the camshaft from adjusting its timing correctly. The screens on the solenoids can also become damaged or go missing, causing issues.
   How to confirm: Check for related codes like P0014. Swap the intake and exhaust solenoids; if the code changes to P0016 (intake correlation), the solenoid is bad. You can also test the solenoid's resistance with a multimeter (should be 6.9-7.9 ohms at 68°F) or apply 12V to see if it actuates.
   Typical fix: Replace the faulty camshaft position actuator solenoid. They are typically replaced in pairs (intake and exhaust) as they are the same age and exposed to the same conditions.
   Est. part cost: $20-$50 per solenoid
3. Low or Dirty Engine Oil 🟡 Medium Probability The Variable Valve Timing (VVT) system is hydraulically operated by engine oil. If the oil level is low, the viscosity is wrong, or the oil is dirty and sludgy, it can't create the pressure needed to operate the cam phasers correctly, leading to correlation codes.
   How to confirm: Check the engine oil dipstick for level and inspect the oil's condition. If it's low or very dirty, this is a likely contributor.
   Typical fix: Perform an oil and filter change using the manufacturer-specified oil viscosity (5W-30 is common for this engine). Clear the code and see if it returns.
   Est. part cost: $30-$70
4. Faulty Camshaft or Crankshaft Position Sensor ⚪ Low Probability While less common than solenoid or timing belt issues, the sensors that read the cam and crank positions can fail, sending incorrect data to the ECM. Owners often replace these first, but they are frequently not the root cause.
   How to confirm: Use a scan tool to monitor live data from the sensors. An oscilloscope is the best tool to verify the sensor's signal pattern. You can also test the sensor's resistance with a multimeter, comparing it to the manufacturer's specification.
   Typical fix: Replace the failed sensor. Note that some vehicles may require a crankshaft position sensor relearn procedure after replacement.
   Est. part cost: $25-$60

Rare But Worth Checking

• Missing Camshaft Actuator Oil Sleeve: According to GM TSB #PIP4543D, this code can appear after a repair involving the camshaft actuators. A unique black plastic oil sleeve between the actuator and the camshaft can be lost or damaged, disrupting oil flow and causing the code. This part is only available with a new camshaft actuator assembly and is a common cause for the code returning immediately after service.
• Failed Camshaft Phaser (Actuator): The mechanical gear (phaser) on the end of the camshaft can fail internally, getting stuck in one position or having a sheared locating pin. This is a more complex and expensive repair than replacing the control solenoid.
• Damaged Reluctor Wheel: The toothed wheel that the crankshaft or camshaft sensor reads can become damaged, bent, or slip on the shaft, causing incorrect readings even with a good sensor.
• Melted/Distorted Oil Restrictor Orifice: An AERA bulletin notes that on 1.6L LXV engines, a plastic oil restrictor orifice in the block deck (exhaust side, between cylinders 2 and 3) can melt or become distorted if the engine has been severely overheated. This can disrupt oil flow to the head and VVT system.

Diagnosis Steps

1. Check Engine Oil: Verify the oil level is correct and the oil is clean and of the proper viscosity (5W-30). Low or dirty oil is a common cause of VVT system problems. If low, top it off. If dirty, perform an oil and filter change.
2. Scan for Other Codes: Check for other related codes like P0016 or P0014, which can help narrow down the diagnosis.
3. Inspect VVT Solenoids: Locate the intake and exhaust VVT solenoids on the top of the engine. Inspect the wiring and connectors for damage, corrosion, or loose connections.
4. Swap VVT Solenoids: A simple diagnostic trick is to swap the exhaust solenoid (Sensor B) with the intake solenoid (Sensor A). Clear the codes and run the engine. If the code changes to P0016 (Intake Correlation), you have confirmed the exhaust solenoid is faulty.
5. Test VVT Solenoid: Remove the suspect solenoid and test its resistance with a multimeter. It should be between 6.9 and 7.9 ohms at room temperature. You can also apply 12V to the terminals to see if the internal piston clicks. Check that the screens are clean and intact.
6. Inspect Mechanical Timing: If all electronic components check out, the next step is to inspect the mechanical timing. This involves removing the timing belt cover and verifying that the timing marks on the camshafts and crankshaft are perfectly aligned. This is the most likely cause if codes appear right after a timing belt service. Check the timing belt for stretching, wear, or damage.
7. Check for TSB Issue: If timing components have recently been serviced, remove the camshaft actuators and inspect them to ensure the black plastic oil sleeves are present and undamaged, per TSB #PIP4543D.

Parts You'll Likely Need

• Exhaust Camshaft Position Actuator Solenoid (OEM #12655421) — This solenoid controls oil flow to the exhaust cam phaser and is a very common failure point, often getting clogged or failing electrically.
• Timing Belt Kit (Belt, Tensioner, Idlers) (OEM #TCK334 (ACDelco kit)) — The timing belt is a maintenance item that can stretch or jump a tooth, directly causing correlation codes. It should be replaced as a complete kit.
• Engine Oil and Filter — Low or dirty oil is a primary cause of VVT system malfunctions. An oil change is a crucial first step in diagnosis.

Related Codes That Often Appear With This One

• P0016 — Crankshaft Position – Intake Camshaft Position Correlation. If both P0016 and P0017 are present, it strongly suggests a base timing issue, like a slipped/mistimed timing belt, rather than a single sensor or solenoid failure.
• P0014 — Exhaust Camshaft Position (CMP) System Performance. This code points more directly to a problem with the control of the exhaust camshaft, often the VVT solenoid or the phaser itself, rather than just a correlation error. It frequently appears with P0017.
• P0106 — Manifold Absolute Pressure (MAP) Sensor Performance. This can appear alongside timing codes because incorrect valve timing leads to erratic engine vacuum, which the MAP sensor reads as an implausible signal.

Technical Service Bulletins (TSBs) & Recalls

• PIP4543D: Details the issue of DTCs P0011, P0014, P0016, or P0017 setting after camshaft actuator service due to a missing or damaged black plastic oil sleeve between the actuator and the camshaft.
• AERA Technical Bulletin (No specific number): Cautions about a melted or distorted plastic oil restrictor orifice in the block deck on 1.6L & 1.8L GM engines that have been severely overheated, which can affect oil flow.

Platform-Specific Known Issues

• TSB #PIP4543D and #PIP4543C mention that DTCs P0016 or P0017 can set after a repair involving the camshaft actuators. This is often caused by a missing or damaged black plastic oil sleeve that fits between the camshaft and the actuator. This part is not sold separately and comes with a new actuator assembly.

Mechanic-Grade Diagnostic Values

• Exhaust Camshaft Position (CMP) Sensor Pin Voltage — expected: Pin 1: Low Reference (Ground), Pin 2: 5V Reference, Pin 3: Signal (pulsing voltage when engine is cranking/running).. Failure: Missing 5V reference, no signal pulse, or a short to ground on any pin.
• Exhaust Camshaft Position (CMP) Actuator Solenoid Connector Voltage — expected: Pin 1: Ignition Voltage (12V with key on), Pin 2: Control Signal (duty-cycled ground from ECM).. Failure: No voltage at Pin 1, or an open/short on the control wire at Pin 2.
• Scan Tool Live Data - Exhaust Camshaft Position Variance — expected: The value in degrees should change in response to bidirectional control commands.. Failure: Value does not change or changes erratically when the solenoid is commanded, indicating a mechanical or hydraulic fault.

Scan Tool Commands That Help

• GDS2 / Tech2: Camshaft Position Actuator Control — This bidirectional command allows the technician to manually command the exhaust VVT solenoid to a specific angle (e.g., 0-20 degrees) while monitoring the camshaft position sensor data. It is used to confirm if the solenoid, oil passages, and phaser are responding to ECM commands, separating electrical from mechanical/hydraulic issues.
• GDS2 / Tech2: Crankshaft Position Variation Learn — This procedure should be performed after replacing the crankshaft position sensor or making significant timing component repairs. While primarily for misfire detection, failing to perform the relearn can sometimes cause other system monitors to run incorrectly.

Wiring & Ground Locations

• G103 — On the left side of the engine block, below the Engine Control Module (ECM).. This is a primary engine ground. A loose or corroded connection at G103 can cause erratic signals from the crankshaft and camshaft position sensors, leading to false correlation codes.
• G104 — On the engine block, next to the starter motor.. Another critical engine ground. Poor contact here can affect the starter and also introduce electrical noise that may interfere with sensor readings.
• ECM Connector X2, Pin 21 (D-BU/WH wire) — At the Engine Control Module, typically located on the driver's side of the engine bay near the battery.. This is the signal wire from the Crankshaft Position Sensor. It can be back-probed to check for a proper signal with an oscilloscope.
• ECM Connector X2, Pin 26 (L-BU/BK wire) — At the Engine Control Module, typically located on the driver's side of the engine bay near the battery.. This is the signal wire from the Exhaust Camshaft Position Sensor. It can be back-probed to check for a proper signal with an oscilloscope.
• ECM Connector, Pin 59 (BN wire) — At the Engine Control Module.. This is the control signal wire for the Exhaust Camshaft Position Actuator Solenoid. It can be tested for activity from the ECM.
