CMP Actuator System Performance Diagnostics

WARNING: This page is about a different car, the 2007 Isuzu i-370, 2007 GMC Canyon, and 2007 Chevrolet Colorado. However, it is still accessible from the selected car via links, so may be relevant.

The powertrain control module (PCM) monitors the performance of the camshaft position (CMP) actuator system by monitoring the actual and desired positions of a Cam Phaser. If the difference between the actual and desired position is more than a calibrated angle for more than a calibrated amount of time, a DTC will set.
