When Monitored
WARNING: This page is about a different variant/trim than selected.
- No active DTCs for CKP Sensor, CMP Sensor, EOT Sensor, EOP Sensor or oil pressure/temperature rationality.
- Cam phasing is commanded off of the default (lockpin) position.
- Oil temperature is between -9°C to 138°C (15°F and 280°F).
- Engine speed is at least 1000 to 1400 rpm, depending on oil temperature.
- Time since Multiple Displacement System (MDS) transition is greater than 0.5 seconds.
- Note the VVT diagnostic will be deactivated during MDS transitions to avoid camshaft fluctuations that can occur as gas exchange is restarted in the de-activated cylinders. The diagnostic is temporarily disabled to reduce the risk of false failure.
- This diagnostic is active when the above enable conditions are met and the modeled camshaft position is continuously moving in a particular direction (advancing or retarding).
