| DTC Strategy |
Case 1 |
- Deviation check between actual CAM position and CAM setpoint position in case of changing setpoint (slow response of actuator)
|
- Poor Connector Connection
- Oil leak
- Oil contamination
- Faulty Oil Control Valve
- Oil Control Valve filter contamination
- Faulty Cam Phaser
- Faulty Intake CVVT Assembly
|
| Case 2 |
- Deviation check between actual CAM position and CAM setpoint position (steady deviation)
|
| Enable Condition |
Case 1 |
- No relevant DTC present
- Camshaft set-point movement more than 11°CRK within in less than 0.8s
- Camshaft set-point moved more than 3 times since engine start
- Engine Speed at between 600 RPM and 1500 RPM or lower than 5000 RPM
- Engine Oil Temp. higher than 68°F (20°C) and lower than 248°F (120° C)
- Battery voltage higher than 11V and lower than 16V
|
| Case 2 |
- No relevant DTC present
- Camshaft set-point moved more than 3times since engine start
- Camshaft set-point not close to full retard position (3°CRK away from full retard position)
- Camshaft set-point minus Actual position more than 5°CRK
- Engine Speed at between 600 RPM and 1500 RPM or lower than 5000 RPM
- Engine Oil Temp. higher than 68°F (20°C) and lower than 248°F (120° C)
- Battery voltage higher than 11V and lower than 16V
|
| Threshold Value |
Case 1 |
- CAM position movement less than 3.4°CRK within 0.8s
|
| Case 2 |
- Integral of Camshaft position actual value - Camshaft position setpoint higher than 40°CRK*s
