Conditions for Setting the DTC
• The ECM detects the difference between the desired
camshaft position and the actual camshaft position
angle is more than 5 degrees.
OR
• The ECM detects the difference between the actual
camshaft angle and the locked position angle is more
than 10 degrees.
• The condition exists for more than 4 seconds.
Action Taken When the DTC Sets
DTCs P0011, P0014, P0021, and P0024 are type B
DTCs.
Conditions for Clearing the DTC

Diagnostic Aids
• The engine oil condition has a major impact on the
camshaft actuator system.
• A low oil level condition may set this DTC. The engine
may require an oil change. Inquire with the customer
when the last oil change was performed. You may
also monitor the Engine Oil Life parameter with a scan
tool. Advise the customer an oil change may be
required.
• Inspect the engine for any recent engine mechanical
repairs. An incorrectly installed camshaft, camshaft
actuator, or timing chain can cause this DTC to set.
Engine General Information and Diagnosis:
Circuit/System Verification
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.
1. Ignition ON, observe the DTC information with a
scan tool. Verify that none of the following DTCs are
set. DTC P0016, P0017, P0018, P0019, P0335,
P0336, P0338, P0341, P0342, P0343, P0346,
P0347, P0348, P0366, P0367, P0368, P0391,
P0392, P0393, P0521, P0522, or P0523.
➢ If any of the DTCs are set, refer to "Diagnostic
Trouble Code (DTC) List - Vehicle Diagnostic
Information: " for further diagnosis.
2. Engine idling, command the suspected camshaft
actuator from 0 degrees to 40 degrees and back to
zero while observing the appropriate CMP Angle
Variance parameters, with a scan tool. The CMP
Angle Variance should be less than 2 degrees in
each of the commanded states.
3. If the vehicle passes the Circuit/System Verification
test, then operate the vehicle within the conditions
for running the DTC. You may also operate the
vehicle within the conditions that are captured in the
Freeze Frame/Failure Records Data List.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at
the appropriate camshaft position (CMP) actuator
solenoid.
NOTE
The test lamp is used to load the circuit and
may not illuminate.
2. Connect a test lamp between the ignition circuit
terminal 1 and the negative terminal of the battery.
3. Ignition ON, test for less than 0.1 volt between the
ignition circuit terminal 1 and the positive battery
terminal.
➢ If greater than 0.1 volt, repair the ignition voltage
circuit for an open/high resistance.
NOTE
Use the J 35616-200 Test Lamp Kit for this
test. If the J 35616-200 is not available, use a
test lamp that measures more than 20 ohms.
