Q: What does code P0008 mean?

Engine Position System Performance (Bank 1). P0008 is a generic powertrain code that indicates the engine control module (ECM) has detected a performance problem with the engine position system on bank 1, which typically involves the relationship between the crankshaft position sensor and the camshaft position sensor. The ECM monitors these signals to determine proper timing and detects when the correlation between them falls outside the expected range, often due to a mechanical timing issue or a faulty sensor.
