| DTC Strategy |
- Slow response error (exhaust)
|
- CVVT assembly (exhaust)
- Engine oil contamination
- Oil leakage
- OCV - Ex (Bank 1)
|
| Enable Conditions |
- (A) Absolute value of difference between target VVT angle and VVT angle is greater than 10 degree
- (B) Engine running time, start at ECT 70°C (158°F) is greater than 10s or start at ECT 0°C (32°F) is greater than 60s
- (C) EOT (calculated from ECT) is between 5 and 135°C (41 and 275°F)
- (D) Engine speed is between 1000 and 5000RPM
- Time after the conditions A+B+C+D is greater than 2s
|
| Threshold Value |
- Absolute value of difference between VVT angle and target angle is greater than 3 degree during 1s
- If maximum variation VVT angle during monitoring cycle is greater than 3 degree
|
| Diagnostic Time |
- Continuous (2s x 5 times)
