If there is a delay or a target error between the target angle and the real angle over 5 times, the ECM sets DTC P0014.
Item | Detecting Condition | Possible Cause | |
Case 1 | DTC Strategy |
•
Target error check(Exhaust) | 1. Poor connection 2. Contamination of Oil / Clog of Oil path 3. OCV(Exhaust) 4. CVVT |
Enable Conditions |
•
| target VVT angle – VVT angle | > 6 deg over 2 sec.
•
