| Case 1 |
DTC Strategy |
- Target error check (Intake)
|
- Poor connection
- Contamination of Oil/Clog of Oil path
- OCV (Intake)
- CVVT
|
| Enable Conditions |
- Absolute value of difference of target VVT angle and VVT angle greater than 6 deg over 2 sec
- Engine running Time, start at ECT 70 °C (158 °F) greater than 10 sec, start at ECT -10 °C (14 °F) greater than 60 sec
- EOT (calculated using the ECT sensor) greater than 40 °C (104 °F) and less than 125 °C (257 °F)
