P0014: Exhaust Camshaft Timing Over-Advanced (Bank 1)
MediumPowertrainEngine/Timing
Symptoms
- Rough or unstable idle
- Reduced engine power
- Poor fuel economy
- Occasional hard starts
Common causes
- Faulty VVT (variable valve timing) solenoid
- Low or dirty engine oil restricting solenoid flow
- Stretched timing chain
- Wiring or connector issue at the solenoid
- Worn camshaft phaser
What to do?
Start with an oil and filter change using the manufacturer's specified viscosity - sludge and wrong-weight oil cause many P0014 cases. If the code persists, test the VVT solenoid and inspect for chain stretch. Do not ignore this code; severe over-advance can damage valves.
