What is the code P0017 on a 2013 Impala?

P0017 on a 2013 Chevrolet Impala indicates the camshaft timing for Bank 1 (Camshaft Position A) is out of sync, typically described as timing over-advanced or a related system performance issue. In practical terms, this points to a problem with the variable valve timing (VVT) system or with the cam/crank timing relationship.

Understanding this code helps drivers differentiate between sensor problems, oil/circulation issues, and mechanical timing concerns. The exact fix depends on the root cause, and addressing it promptly can prevent rough running, reduced power, and potential further damage.

What P0017 Means for the 2013 Impala

In everyday terms, P0017 signals that the PCM has detected a cam timing discrepancy tied to Bank 1 and Camshaft Position A. This can degrade engine performance, trigger the check engine light, and in some cases lead to limp-home mode. Repairs range from sensor or wiring fixes to more involved timing-chain or VVT component work.

Common causes

Common causes are typically grouped into electrical/sensor faults and mechanical timing/oil-system issues. The list below outlines the most frequent culprits in the 2013 Impala.

Electrical and sensor issues

• Faulty camshaft position sensor (CMP) A or its wiring harness

Mechanical timing and oil-system issues

• Worn or stretched timing chain and/or drifted sprockets or tensioner


• Faulty or sticking variable valve timing (VVT) solenoid or phaser


• Low oil pressure or dirty oil that impedes VVT operation


• Incorrect oil grade or contaminated oil affecting timing components

Each of these categories can independently or collectively cause P0017. A professional diagnosis helps confirm the exact culprit and prevent unnecessary replacements.

Symptoms you may notice

If P0017 is active, drivers may observe one or more of the following indicators.

• Check Engine Light (MIL) illuminated with code P0017


• Rough idle, misfires, or engine hesitations


• Reduced power or sluggish acceleration


• Increased fuel consumption or poor overall drivability


• Occasional stalling or difficulty starting, especially when cold


• Noise from the engine indicating timing concerns (rare but possible)

Not every vehicle will display all symptoms, and some drivers may notice symptoms intermittently. If P0017 appears, a diagnostic check is advised.

Diagnostic steps and potential repairs

Below is a practical diagnostic approach used by technicians to identify the root cause. The steps assume basic automotive repair knowledge and safe handling practices.

1. Retrieve and analyze all stored codes with a scan tool, focusing on P0017 and any related codes (such as P0016, P0018, or P0019). Review freeze-frame data for engine load, RPM, and temperature at the time of failure.


2. Inspect the camshaft position sensor A (Bank 1) circuit, wiring, and connectors for corrosion, damage, or loose connections. Verify the sensor’s reference voltage and signal with a multimeter or oscilloscope if available.


3. Check the crankshaft position sensor and its wiring, since timing correlation depends on accurate crank and cam signals. Look for damage or misalignment that could affect timing data.


4. Assess the timing chain, tensioner, and sprockets for wear, slack, or jumping. If the chain shows signs of wear or if timing marks don’t align as specified, timing-related repairs are likely necessary.


5. Test the VVT solenoids/phasers and verify oil supply to the system. Check for proper oil pressure, clean oil passages, and ensure no contamination or sludge is restricting movement. Replace clogged solenoids if needed.


6. Check oil level and viscosity; use the manufacturer-recommended grade. Consider an oil change if the oil is dirty or degraded, as oil quality can affect VVT operation.


7. Attempt a software update or re-learn procedure for the VVT system if recommended by the service bulletin or OEM guidelines. Some vehicles require a specific tool to re-align the cam timing strategy after parts are replaced.


8. Clear the codes and perform a road test to verify that the code does not reappear and that engine performance returns to normal. If P0017 returns, re-check all components and consider replacing the timing chain/tensioner or VVT components as indicated by the diagnosis.

If you are not experienced with timing-related repairs, these steps should be performed by a qualified technician. Incorrect timing work can cause severe engine damage.

Summary

P0017 on a 2013 Impala flags a cam timing issue for Bank 1, specifically Camshaft Position A, typically signaling a problem with the VVT system or timing relationship. Causes span electrical/sensor faults to mechanical timing components and oil-related problems. Symptoms often include a checked engine light, rough idle, and reduced performance. A methodical diagnostic approach—codes review, sensor and wiring checks, timing verification, VVT solenoid and oil-system inspection, and appropriate repairs—helps identify the exact cause. Prompt diagnosis and repair can restore performance and prevent further engine damage. If in doubt, consult a professional technician.

How do I fix error code P0017?

To fix a P0017 code, start with the simplest and most common causes: check and change your engine oil, then inspect the variable valve timing (VVT) solenoid and its wiring. If the problem persists, further steps include checking the camshaft and crankshaft timing marks, replacing the camshaft position sensor, or repairing any damage to the timing chain and its components. 
1. Check and service engine oil

• Why: The VVT system relies on clean engine oil. Low or dirty oil can cause sludge buildup that clogs the VVT solenoid, triggering the P0017 code. 
• How:
  • Check your oil level and condition. If it's low or dirty, perform an oil and filter change immediately. 
  • Use the correct grade of oil as specified in your owner's manual.

2. Inspect the variable valve timing (VVT) solenoid 

• Why: The VVT solenoid can become clogged with sludge or fail electrically, disrupting the timing. 
• How:
  • Locate the VVT solenoid (usually on the exhaust side of the engine for this code). 
  • Inspect its wiring for any damage, corrosion, or loose connections. 
  • Test or replace the solenoid, as its internal screen can get clogged with oil sludge. 

3. Examine the camshaft and crankshaft timing 

• Why: A P0017 code indicates a timing correlation error between the crankshaft and camshaft. If the timing chain has slipped or the timing marks are misaligned, the code will set. 
• How:
  • Visually inspect the timing marks on the camshaft and crankshaft to ensure they are properly aligned. 
  • If you find they are off, you may need to re-time the engine, which can involve resetting the cam timing. 
  • Inspect the timing chain for stretching or a failed tensioner.

4. Check the camshaft and crankshaft position sensors 

• Why: A faulty camshaft position sensor, particularly the exhaust "B" sensor for Bank 1, or a problem with the crankshaft position sensor can cause this code. 
• How:
  • Locate the sensors and check their wiring for damage. 
  • Test the sensors with a multimeter to ensure they are within the manufacturer's specifications. 
  • Replace the sensor if it is faulty. A "relearn" procedure may be necessary after replacement. 

5. Consider other potential issues

• Wiring: Repair any damaged wiring to the camshaft position sensor or the oil control valve (OCV). 
• Engine Carbon: Carbon buildup on the pistons and valves can sometimes cause timing issues. 
• Engine Control Module (ECM): In rare cases, the ECM itself may be faulty. 
• Timing Gears/Chain: Issues with timing gears, chains, and guides can also cause the P0017 code.
