What are the Possible Causes of the DTC P0011 Chevrolet?

NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
  • Low or Dirty Engine Oil
  • Faulty Intake Camshaft Position Actuator Solenoid
  • Intake Camshaft Position Actuator Solenoid harness is open or shorted
  • Intake Camshaft Position Actuator Solenoid circuit poor electrical connection
  • Faulty Engine Control Module (ECM)

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 P0011 Chevrolet Code Mean?

The Camshaft Position (CMP) actuator system enables the Engine Control Module (ECM) to change the timing of the camshafts while the engine is operating. The Camshaft Position Actuator Solenoid Valve signal from the ECM is Pulse Width Modulated (PWM). The ECM controls the Camshaft Position Actuator Solenoid Valve duty cycle by controlling the amount of solenoid valve ON time. The Camshaft Position Actuator Solenoid Valve controls the advance or the retard of each camshaft. The Camshaft Position Actuator Solenoid Valve controls the oil flow that applies the pressure to advance or retard the camshafts.
Ignition voltage is supplied directly to the Camshaft Position Actuator Solenoid Valve. The ECM controls the solenoid valve by grounding the control circuit with a solid-state device called a driver. The driver is equipped with a feedback circuit that is pulled up to a voltage. The ECM can determine if the control circuit is open, shorted to the ground, or shorted to a voltage by monitoring the feedback voltage.
The Diagnostic Trouble Code (DTC) will be set when the ECM detects an open solenoid circuit in the CMP actuator for greater than 1 second or a cumulative of 5 seconds when the solenoid is commanded OFF.
The ECM monitors the performance of the camshaft position (CMP) actuator system by monitoring the calibrated desired position and the actual position of the camshaft, through the 4X signal of the CMP sensor. If the difference between the actual and the desired position is greater than a calibrated angle for a calibrated amount of time, DTC P0011 will be set.
