* DTC P0010, P0013, P0016, P0017, P0018, P0019, P0020, P0023, P2088, P2089, P2090, P2091, P2092, P2093, P2094, and P2095 is not set.
* The engine speed is greater than 560 RPM.
* The engine is operating for greater than 1 s.
* The engine coolant temperature is between -48 to +143掳C (-54 to +289掳F).
* The engine oil temperature is less than -48掳C (-54掳F).
* The engine must accelerate such that the camshaft position 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 s 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
20 s.
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 6-11
degrees.
OR
* The ECM detects a slow response, a deviation greater than 3 degrees in time greater than 4 s, for the actual camshaft position angle to match
the desired position angle during the test.
* Either condition exists for greater than 1 s or for a cumulative time of 4 s.
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
