Diagnostic Aids

WARNING: This page is about a different variant/trim than selected.

Inspect for any recent engine mechanical repairs. An incorrectly timed or incorrectly installed camshaft can cause a DTC P0011 to set.

If a DTC P0012 and P0011 are both present, inspect for a malfunctioning CMP solenoid valve. Observe that the Cam Phase Angle and Cam Phase Angle Desired parameters on a scan tool are approximately equal. A difference in the 2 parameters indicates that the CMP solenoid may be sticking.

An intermittent malfunction may be caused by a fault in the electrical circuit of the CMP actuator valve. Inspect the wiring harness and components for an intermittent condition. Refer to Intermittent Conditions .

The information included in the Freeze Frame data can be useful in determining the vehicle operating conditions when the DTC first set.
