P0014 moderate

Exhaust Camshaft Position Timing Over-Advanced (Bank 1)

What does P0014 mean?

The P0014 code means the vehicle's onboard diagnostic system has detected: Exhaust Camshaft Position Timing Over-Advanced (Bank 1). This is a moderate severity code.

Common Symptoms

  • Check Engine Light on
  • Rough idle
  • Rattling on startup
  • Reduced power
  • Poor fuel economy

Probable Causes (Ranked by Likelihood)

  • Stuck exhaust OCV allowing over-advance Very High
  • Oil sludge in actuator passages High
  • Low oil pressure Moderate
  • Worn timing components Moderate
  • PCM fault Low

Step-by-Step Diagnostic Procedure

  1. Change engine oil and filter, then clear the code and retest.

  2. Monitor exhaust cam timing with a scan tool. A reading ahead of target confirms over-advance.

  3. Test exhaust OCV for proper operation: resistance check and commanded response.

  4. Check timing chain tension if other VVT codes are also present.

  5. Inspect oil passages for blockages.
