| Case 1 |
DTC Strategy |
- Target error check (Intake)
|
- Poor connection
- Contamination of oil/clogged oil path
- OCV (Intake)
- CVVT
|
| Enable Conditions |
- Difference between absolute value and target VVT angle is greater than 6° over 2 seconds
- Engine running time, start at ECT 70°C (158°F) greater than 10 seconds, start at ECT -10°C (14°F) greater than 60 seconds
- Engine oil temperature (calculated using the ECT sensor) greater than 40°C (104°F) and less than 125°C (257°F)
- RPM: 1000 ~ 6600rpm
|
| Threshold Value |
- Counter (variation of VVT angle less than 3°) over 5 times
|
| Case 2 |
DTC Strategy |
- Slow response check (Intake)
|
| Enable Conditions |

- Engine running time, start at ECT 70°C (158°F) greater than 10 seconds, start at ECT -10°C (14°F) greater than 60 seconds
- Engine oil temperature (calculated using the ECT sensor) greater than 0°C (32°F) and less than 130°C (266°F)
- RPM: 1000 ~ 6600rpm
|
| Threshold Value |
- Counter (variation of VVT angle greater than 3°) over 5 times
