What does Error Code P0008 mean?
Critical Issue
DTC Code P0008 indicates an Engine Positions System Performance issue on Bank 1. This code is triggered when the Engine Control Module (ECM) detects a misalignment between the camshafts and the crankshaft, exceeding the calibrated threshold during idle.
What are the symptoms of Error Code P0008?
- Engine Light ON: The illumination of the engine light or service engine soon warning light is a primary indicator of DTC P0008. This symptom suggests a potential issue with the engine position system performance on Bank 1, which may be linked to timing chain or belt problems.
What causes Error Code P0008?
- Engine mechanical problems can lead to misalignment of the timing components, affecting engine performance.
- An incorrect timing chain installation can cause the engine's timing to be off, resulting in poor performance.
- A stretched timing chain can lead to improper synchronization between the crankshaft and camshaft, causing the engine to run inefficiently.
- A failed camshaft actuator or actuator solenoid can disrupt the timing of the camshaft, leading to performance issues in the engine.

How to fix Error Code P0008?
- Verify DTC Code: Confirm the presence of DTC P0008 using an OBD-II scanner. Check for any additional codes that may be related, such as P0009, P0016, P0017, P0018, or P0019.
- Inspect Timing Chain/Belt: Examine the timing chain or belt for wear, stretching, or misalignment. A worn or stretched timing chain/belt can cause incorrect engine position readings.
- Check Camshaft and Crankshaft Sensors: Inspect the camshaft and crankshaft position sensors for damage or malfunction. Ensure the sensors are properly connected and functioning.
- Evaluate Timing Components: Assess the condition of timing components such as tensioners, guides, and sprockets. Replace any components that show signs of wear or damage.
- Perform Engine Timing Verification: Verify the engine timing using manufacturer specifications. Ensure the timing marks align correctly on the camshaft and crankshaft.
- Test Engine Control Module (ECM): Check the ECM for any faults or updates. Reprogram or replace the ECM if necessary to ensure accurate engine position readings.
- Conduct a Road Test: After repairs, perform a road test to ensure the issue is resolved and the DTC P0008 does not reappear.
