* The engine is operating for greater than 1 second.

* The ECM completed the CMP actuator solenoid output driver test.

* The engine speed is greater than 1,000 RPM.

* DTCs P1011, P1012, P1013, and P1014 run once at engine start-up, in approximately 10 seconds.

Conditions for Setting the DTC

The ECM detects that the average of the actual camshaft angle measurements is greater than 10 degrees of the parked position angle on an engine

start-up.

Action Taken When the DTC Sets

DTCs P1011, P1012, P1013, and P1014 are type C DTCs.

Conditions for Clearing the DTC

DTCs P1011, P1012, P1013, and P1014 are type C DTCs.

Diagnostic Aids

* Inform the customer that the following actions may cause DTCs P1011, P1012, P1013, or P1014 to set:

- Turning the engine OFF while the accelerator pedal is pressed

- Turning the engine OFF while driving

- Pressing the accelerator pedal to start the engine

* If the customers concern is that the engine is stalling, refer to Symptoms - Engine Controls (See: Powertrain Management/Computers and

Control Systems/Testing and Inspection/Symptom Related Diagnostic Procedures/Symptoms - Engine Controls) for further diagnosis.

Circuit/System Verification

1. Ignition ON, clear the DTC information with a scan tool.

Note: The engine oil level and the oil pressure are critical to the correct operation of the camshaft position (CMP) actuator system. Verify

that the engine has the correct oil level and the correct oil pressure before continuing with this diagnostic. Refer to Fluid and Lubricant

Recommendations (USA and Canada) (See: Maintenance) and Oil Pressure Diagnosis and Testing (See: Engine, Cooling and

Exhaust/Engine/Testing and Inspection/Component Tests and General Diagnostics/Oil Pressure Diagnosis and Testing) for more information.

2. Start the engine. Verify there is no abnormal engine noise during start up. Observe the DTC information with a scan tool. DTC P1011,

P1012, P1013, or P1014 should not set.
