When Monitored
WARNING: This page is about a different car, the 2015 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.
The 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.
