• OBD2 Code: P0008
• Description: Engine Positions System Performance Bank 1
• Definition: This code indicates that the engine control module (ECM) has detected a problem with the timing between the crankshaft and camshaft in bank 1. It typically relates to issues with the timing chain or belt, tensioners, or related components.

p0008 – Engine Positions System Performance Bank 1

Typical Severity: Severe

Common Causes

P0008 – Engine Positions System Performance Bank 1

Common Causes:

• Timing chain stretched or skipped teeth
• Incorrect camshaft timing due to a worn timing chain tensioner
• Faulty camshaft phaser
• Low engine oil level or dirty engine oil causing improper lubrication
• Malfunctioning crankshaft position sensor

 

Common Misdiagnosis

OBD2 Code: P0008

Description: Engine Positions System Performance Bank 1

Common Misdiagnosis: Replacing the timing chain or belt without checking for other possible causes such as a faulty camshaft position sensor or crankshaft position sensor.

 

Common Diagnostic Steps

OBD2 Code: P0008

Description: Engine Positions System Performance Bank 1

• Verify the code with an OBD-II scanner and note any additional codes.
• Inspect the timing chain or belt for wear or damage.
• Check the camshaft and crankshaft position sensors for proper operation.
• Examine the variable valve timing (VVT) solenoids for blockages or malfunctions.
• Ensure that the engine oil level and quality are adequate, as poor oil condition can affect VVT performance.
• Test the engine control module (ECM) for faults if other components appear to be functioning correctly.
• If necessary, replace faulty components such as sensors, solenoids, or timing chains/belts.
• Clear the code and perform a test drive to ensure it does not return. Re-scan to confirm resolution.
