P0011 2018 Chevrolet Silverado Code - Intake Camshaft Position System Performance
Quick Answer
The Camshaft Position (CMP) actuator system enables the Engine Control Module (ECM) to change the timing of the camshafts while the engine is operating. Common causes include Low or Dirty Engine Oil, Faulty Intake Camshaft Position Actuator Solenoid, Intake Camshaft Position Actuator Solenoid harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0011 2018 Chevrolet Silverado Description
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.
What are the Possible Causes of the DTC P0011 2018 Chevrolet Silverado?
- 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)
