What does P0014 mean?
The exhaust camshaft on Bank 1 is over-advanced — the exhaust-side counterpart to P0011.
Quick Decision Guide
- Low or dirty engine oil
- Faulty exhaust oil control valve (OCV)
- Clogged VVT oil passages
When to stop driving
Same guidance as P0011 — if oil is critically low or there is audible engine knocking, stop driving immediately. Otherwise drive cautiously to a workshop.

Understanding P0014 in detail
P0014 is the exhaust-side equivalent of P0011, indicating the exhaust camshaft on Bank 1 is advanced beyond the ECM's commanded position. The root causes and diagnostic approach are nearly identical to P0011: oil quality and level are the primary suspects, followed by the exhaust oil control valve and timing chain. The exhaust camshaft phaser uses the same oil-pressure-controlled mechanism as the intake side. Low or degraded oil starves the phaser, causing it to drift. The main difference is that P0014 specifically implicates the exhaust cam, which may point to the exhaust-side OCV solenoid rather than the intake side.
Symptoms of P0014
- Check engine light on
- Rough idle on cold start
- Rattling or ticking from engine
- Reduced power and efficiency
Common causes
- Low or dirty engine oil
- Faulty exhaust oil control valve (OCV)
- Clogged VVT oil passages
- Worn or stretched timing chain
- Failed exhaust camshaft phaser
