P0008 OBD-II: Engine Position System Performance

What Does P0008 Code Mean?

OBD-II Code P0008 is defined as a Engine Position System Performance

The engine control module (PCM) uses a signal from the camshaft position sensor to determine the proper time to fire the fuel injector and ignite the spark plug. The PCM compares this signal to the signal from the crankshaft to determine if the engine is timed properly. Newer vehicles use a variable timing system to adjust the timing of the camshaft in relation to the crankshaft to increase fuel efficiency and performance. If the Camshaft is not in the correct position relative to the crankshaft, the PCM will set code P0008.

P0008 Symptoms

• Decreased engine performance
• Increased fuel consumption

Common Problems That Trigger the P0008 Code

• Camshaft variable timing solenoid failure
• Engine oil level is too low
• The engine is not timing correctly
• The engine oil does not meet the manufacturer's requirements
• Variable valve timing actuator failure
• Worn timing chain

Common Repairs Needed for the P0008 Code
