P0014: Exhaust Camshaft Position Timing Over-Advanced (Bank 1)
Can you still drive? Use caution. If the engine is stalling, do not drive. Check oil level first and change oil if it is dirty or overdue.
What Does P0014 Mean?
Code P0014 indicates that the exhaust camshaft on bank 1 is more advanced than the ECM has commanded. This means the exhaust valves are opening earlier than expected, which can negatively affect engine performance, idle quality, and emissions. The problem often relates to oil flow issues or a malfunctioning VVT actuator.

Frequently Asked Questions
Can low oil cause P0014?
Yes, low oil level or low oil pressure is one of the most common causes. The VVT system relies on oil pressure to adjust timing.
Is P0014 the same as P0011?
They are similar but P0011 refers to the intake camshaft and P0014 refers to the exhaust camshaft. Both indicate over-advanced timing on bank 1.
