Code Tech Notes

Recommendation/Instructions
In rare instances, the P0011 and or P0014 diagnostic codes are set in the ECM as history or current. If the diagnostics do not lead to a resolution, remove the camshaft solenoids, and inspect the screens for debris. If debris is present, clean off the screens with brake cleaner. Reinstall the solenoids and evaluate if the DTC still sets. If the code resets or the screen does not have debris on them, remove the camshaft actuator associated with the DTC(s). With light air pressure, blow out the oil passages through the camshaft actuator solenoid port in the head while holding a rag over the camshaft actuator oil passages to keep the oil from spraying out all over the vehicle/engine. Lubricate the camshaft solenoid seal(s) with clean engine oil and reinstall. Install a new camshaft actuator associated with the code(s). Evaluate the vehicle and monitor the camshaft actuator activity.

What Does the P0014 Chevrolet Code Mean?

The Camshaft Position (CMP) actuator is attached to each camshaft and is hydraulically operated in order to change the angle of the camshaft relative to Crankshaft Position (CKP). The CMP actuator solenoid is controlled by the control module. The control module sends a pulse width modulated 12-volt signal to a CMP actuator solenoid. The solenoid controls the amount of engine oil flow to a CMP actuator. The CMP actuator can change the camshaft angle a maximum of 25 degrees. The control module increases the pulse width to accomplish the desired camshaft operation.
