Related Codes
The intake camshaft on bank 1 is more advanced than the ECM commanded. This typically means the VVT system is stuck or the oil flow is restricted. Often caused by dirty oil or a stuck VVT solenoid.
The ECM detected a fault in the exhaust camshaft VVT solenoid circuit on bank 1. This solenoid controls exhaust valve timing for optimal performance and emissions.
The intake camshaft on bank 1 is more retarded than commanded by the ECM. This reduces engine performance and efficiency. Often related to oil viscosity issues or a failing VVT actuator.
Frequently Asked Questions
- Will P0014 cause damage?
- If left unfixed, P0014 can lead to poor performance and potential timing chain wear. Fix the underlying oil or solenoid issue promptly.
- Can dirty oil cause P0014?
- Yes, dirty oil is the #1 cause. Sludge blocks the VVT solenoid and passages, preventing proper camshaft timing.
