Conditions for Setting the DTC
P0011 and P0021
The ECM detects the difference between the desired and actual camshaft position angle is greater than 5 degrees for greater 2.5 s.
P0014 and P0024
The ECM detects the difference between the desired and actual camshaft position angle is greater than 5 degrees for greater 10 s.
Action Taken When the DTC Sets
DTCs P0011, P0014, P0021, and P0024 are type B DTCs.
Conditions for Clearing the DTC
DTCs P0011, P0014, P0021, and P0024 are type B DTCs.
Diagnostic Aids
Inspect the engine for any recent engine mechanical repairs. An incorrectly installed camshaft, camshaft position actuator solenoid, mechanical
camshaft actuator, or timing chain can cause this DTC to set.

Circuit/System Verification
Note:
* The engine oil level and the oil pressure are critical to the correct operation of the camshaft position actuator system. Verify that the
engine has the correct oil level and the correct oil pressure before continuing with this diagnostic. Refer to Oil Pressure Diagnosis and
Testing (See: Engine, Cooling and Exhaust/Engine/Testing and Inspection/Component Tests and General Diagnostics/Oil Pressure
Diagnosis and Testing).
* The engine oil condition has a major impact on the camshaft actuator system. Debris in the oil can interfere with the camshaft position
actuator solenoid and the mechanical camshaft actuator operation. Inspect for dirty or degraded crankcase oil. The engine may require an
oil change. Inquire with the customer when the last oil change was performed. You may also monitor the scan tool Engine Oil Life
parameter. Advise the customer an oil change may be required.
* If a crankshaft or camshaft position sensor DTC is set, the Camshaft Position Actuator output control will not function.
1. Ignition ON, observe the scan tool DTC information. Verify that DTC P0016, P0017, P0018, P0019, P0335, P0336, P0338, P0340, P0341,
P0345, P0346, P0365, P0366, P0390, or P0391 is not set.
