P0011 GMC 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 GMC 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 GMC?
- 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 GMC?
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.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P0011 GMC code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

I have a 2007 GMC Sierra 6.0 motor I have problem with it I get the code p0011 and I had already replace oil pump cam sensor crank sensor DOD play the actuator that goes on the timing cover and nothing that code make my transmission kick I already went through 5 transmission And the cam gear is new to

Unfortunately, I haven't had that problem before, usually replacing the engine oil or the Variable Valve Timing Control Solenoid takes care of the problem. I checked a national database of repair for your model and year, and here is the list of most probable cause with the number of repairs done.
Variable Valve Timing Control Solenoid - 17 times this fixed the code
Camshaft Position Sensor - 16
Engine Oil Pressure Sensor - 4
Crankshaft Position Sensor - 3 -
Variable Valve Timing Control Solenoid I replaced it and the camshaft position sensor and the crankshaft position sensor I haven’t replaced the engine oil pressure sensor
-
Any other symptoms besides the code? the problem with the transmission should not be related to the P0011 code.
-
When I erase the code the truck runs fine but once the code comes back up it starts kicking into second gear

I have a 2007 GMC Yukon Denali 6.2L. Just rebuilt the motor, this code keeps coming on. Everything has been replaced. When the code comes on the oil pressure does not work any more till I reset the code and turn off the car. Next time I start the car the oil pressure sensor works but I also have a lot of smoke come out of the back at startup.

Since I don't know exactly what parts you have replaced, here is the list of the most common parts that will set the P0011 code. Do you have any other codes, besides the P0011?
- Camshaft Position Sensor
- Variable Valve Timing Control Solenoid
- Engine Oil Pressure Sensor
- Powertrain Control Module
- Variable Valve Timing Actuator -
I had same issue and replaced all the sensors oil plugs and wires they said it was my harness to cam sensor come to find out they didn't wire the new harness up right so might check the connections to the sensors
