p0011 code pontiac g6 Sign In

car seemed to buck and kick when it gets warm out so i put a good quality code reader to it . found that code poo11 camsensor fault 2 degrees advanced timing. i replaced both sensors bank 1 and 2 car still acts the same and brings up same code ???

Here's some info on that code. Just a note..... One thing that is very important with these variable cam timing engines is the oil viscosity. You must use the recommended oil weight of 5W30




DTC P0011

DTC DESCRIPTOR

DTC P0010
Intake Camshaft Position (CMP) Actuator Solenoid Control Circuit

DTC P0011
Intake Camshaft Position (CMP) System Performance

DTC P0013
Exhaust Camshaft Position (CMP) Actuator Solenoid Control Circuit

DTC P0014
Exhaust Camshaft Position (CMP) System Performance

DIAGNOSTIC FAULT INFORMATION

IMPORTANT: Always perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.



CIRCUIT/SYSTEM DESCRIPTION
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 camshaft position (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.

CONDITIONS FOR RUNNING THE DTC P0010 AND P0013
The engine is running.

CONDITIONS FOR RUNNING THE DTC P0011 AND P0014
  • The engine speed is more than 1,350 RPM .
  • The engine control module (ECM) has enabled the CMP actuator.
  • The system voltage is more than 11 volts .
  • DTC P0011 and P0014 run continuously when the above conditions are met.

CONDITIONS FOR SETTING THE DTC P0010 AND P0013
The ECM detects an open, short to ground, or a short to voltage on the high control circuit or an open on the low reference circuit for more than 0.25 second .

CONDITIONS FOR SETTING THE DTC P0011 AND P0014
  • The control module has enabled the CMP actuator.
  • The difference between the desired CMP actuator angle and the actual CMP actuator angle is more than 6 degrees .
  • The CMP actuator is steady for 3 seconds .
  • The condition is present for 13.5 seconds .

ACTION TAKEN WHEN THE DTC SETS
  • The control module illuminates the malfunction indicator lamp (MIL) when the diagnostic runs and fails.
  • The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Freeze Frame and/or the Failure Records.
  • The control module commands the TAC system to operate in the Reduced Engine Power mode.
  • A message center or an indicator displays Reduced Engine Power.
  • Under certain conditions the control module commands the engine OFF.

CONDITIONS FOR CLEARING THE MIL/DTC
  • The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
  • A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
  • A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
  • Clear the MIL and the DTC with a scan tool.

CIRCUIT/SYSTEM VERIFICATION
  1. Ensure the vehicle has the proper oil viscosity.
  2. Observe the engine oil level. The engine oil level should be within the operating range.
  3. Allow the engine to reach operating temperature.
  4. Increase the engine speed to 1,500 RPM .
  5. Command each CMP actuator to 25 percent . The CMP actuator angle desired parameter should match the CMP actuator actual parameter.

CIRCUIT/SYSTEM TESTING
  1. With the ignition ON, measure for battery voltage between the CMP actuator solenoid high control of the affected actuator and a ground.
    • If less than battery voltage, test the CMP actuator high control circuit for an open, short to ground, or a faulty ECM.
  1. Connect a test lamp between the CMP actuator solenoid high control of the affected actuator and a good ground. The test lamp should not illuminate.
    • If the test lamp illuminates, test the CMP actuator high control circuit for a short to voltage or a faulty ECM.
  1. Command each CMP actuator solenoid between 0-50 percent . The test lamp should turn ON and OFF.
    • If the test lamp does not turn ON and OFF, test the CMP actuator high control circuit for high resistance or for a faulty ECM.
  1. Connect a test lamp between the low reference circuit of the CMP actuator solenoid of the affected actuator and battery voltage. The test lamp should illuminate.
    • If the test lamp does not illuminate, test the low reference circuit for an open, high resistance, or a faulty ECM.
  1. Determine that the vehicle has the correct engine oil. Refer to Service and Appearance Care in the owner's manual.
    • If the engine oil life system monitor displays the Change Oil Soon message, the engine oil is more than one year old, contains additives, or is not the correct viscosity, change the oil.
  1. Test the engine oil pressure. Refer to Oil Pressure Diagnosis and Testing.
    • If the oil pressure is low, correct the low pressure first.
  1. Inspect each CMP actuator solenoid valve assembly for the following:
    • Torn screens
    • Debris on the screens
    • Debris clogging the oil ports
    • Missing screens
    • Oil seepage at the solenoid connector pins
  1. Inspect for the following conditions:
    • Excessive timing chain play
    • Proper installation of the CMP actuator assembly

COMPONENT TESTING
  1. Measure the resistance of each CMP actuator solenoid valve assembly. Resistance should be between 8-12 ohms .
  2. Connect a jumper wire between the CMP actuator low reference circuit at the solenoid and a good ground. Connect a fused jumper wire to the CMP actuator high control circuit at the solenoid. Momentarily touch the fused jumper to B+. Observe the spool valve inside the CMP actuator. The spool valve should move from fully closed to fully opened position.
