P0011 Cadillac 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 Cadillac 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 Cadillac?
- 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)
How to Fix the DTC P0011 Cadillac?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
Code Tech Notes
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.

How much should a ECM replacement cost at a dealer? What about if it is a solenoid problem? Just don't want to get ripped off. Thanks!
-
An ECM is over $700, but you shouldn't start with the ECM. Start by changing engine oil and filter and clear the code.

I have a 2013 Cadillac ATS 2.0L turbo with the check engine light on and a P0011 code. I bought the car used and changed the oil and two days later the check engine light came on. I took it to a mechanic who checked the code and advised to clear the code and wait and see if it came back. About a week later the check engine light came back on and the code came up again as P0011. The mechanic advised that I change the camshaft position sensor. Will see if this fixes it.
-
I hope that fixes the problem. Do you know what oil weight did mechanic used? make sure you use the factory recommended oil wight.
