2010 Cadillac CTS Sedan AWD V6-3.6L Page 778
* The engine is operating for greater than 1 seconds.
* The engine speed is greater than 520 RPM.
* The engine must accelerate such that the CMP actuator system is commanded from the park position to the phased position. This is
considered a cam control cycle. There must be a minimum of 2 cam control cycles for at least 2.5 seconds each in the phased position.
* DTCs P000A, P000B, P000C, P000D, P0011, P0014, P0021, and P0024 run continuously once the above conditions are met for greater than
600 seconds.
Conditions for Setting the DTC
* The ECM detects the difference between the desired camshaft position angle and the actual camshaft position angle is greater than 7-8
degrees.
OR
* The ECM detects a slow response, a deviation greater than 1.5 degrees in time greater than 2 seconds, for the actual camshaft position angle
to match the desired position angle during the test.
* Either condition exists for greater than 1 second or a cumulative of 10 seconds.
Action Taken When the DTC Sets
DTCs P000A, P000B, P000C, P000D, P0011, P0014, P0021, and P0024 are type B DTCs.
Conditions for Clearing the DTC
DTCs P000A, P000B, P000C, P000D, P0011, P0014, P0021, and P0024 are type B DTCs.

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 scan tool Engine Oil Life parameter. 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.
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 scan tool DTC information. Verify that DTC P0016, P0017, P0018, P0019, P0335, P0336, P0338, P0341, P0342,
