When Monitored:
WARNING: This page is about a different car, the 2011 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
Variable Cam Timing (VCT) phasing accuracy is monitored under the following conditions: (1) Engine speed is at least 150 rpm; (2) No CMP sensor or CKP sensor plausibility errors. This is performed even when phasing control is not enabled, to verify the actuator is keeping the camshaft at the default (lockpin) phase.
