| DTC Strategy |
Case1 |
- Deviation check between actual CAM position and CAM setpoint position in case of changing setpoint (slow response of actuator)
|
- Oil leak
- Oil Control Valve
- CVVT Assembly
|
| Case2 |
- Deviation check between actual CAM position and CAM setpoint position (Intake VVT Steady deviation)
|
| Enable Conditions |
Case1 |
- Camshaft setpoint moving by more than 12°CRK within less than 0.80 sec.
- Camshaft setpoint moved more than 5 times since engine start
- 11V < Battery voltage < 16V
- 600 to 1500< Engine speed (RPM) < 5000
- Time after start > 2 sec.
- 20°C (68°F) < Engine oil temp. < 120°C (248°F)
|
| Case2 |
- Time after start > 2 sec.
- CVVT control active
- Camshaft setpoint moved more than 5 times since engine start
- Camshaft setpoint not close to full retard position
- CAM set-point - Actual position > 5°CRK
- 11V < Battery voltage < 16V
- 600 to 1500 < Engine speed (RPM) < 5000
- 20°C (68°F) < Engine oil temp. < 120°C (248°F)
|
| Threshold Value |
Case1 |
- CAM position movement < 3.4 °CRK within 0.8 sec. (with CAM setpoint moving by 12 °CRK)
|
| Case2 |
- Integral of Camshaft position actual value - Camshaft position setpoint > 45°CRK/sec.
