2010 Cadillac Truck SRX AWD V6-2.8L Turbo Page 980
P2088, P2090, P2092, P2094
The ECM detects a short to ground in the Camshaft Position Actuator Solenoid Valve circuits for greater than 1 s or a cumulative of 5 s, when the
solenoid valve is commanded OFF.
P2089, P2091, P2093, P2095
The ECM detects a short to voltage in the Camshaft Position Actuator Solenoid Valve circuits for greater than 1 s or a cumulative of 5 s, when the
solenoid valve is commanded ON.
Action Taken When the DTC Sets
DTCs P0010, P0013, P0020, P0023, P2088, P2089, P2090, P2091, P2092, P2093, P2094, and P2095 are type B DTCs.
Conditions for Clearing the DTC
DTCs P0010, P0013, P0020, P0023, P2088, P2089, P2090, P2091, P2092, P2093, P2094, and P2095 are type B DTCs.
Diagnostic Aids
If the condition is intermittent, move the related harnesses and connectors, with the engine operating, while monitoring the scan too circuit status
parameters for the component. The circuit status parameters change from OK or Not Run to Fault if there is a condition with the circuit or a
connection.

Circuit/System Verification
1. With the engine at normal operating temperature, raise the engine speed to 2,000 RPM for 10 s. DTCs P0010, P0013, P0020, P0023, P2088,
P2089, P2090, P2091, P2092, P2093, P2094, or P2095 should not set.
2. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the
conditions that you observed from the Freeze Frame/Failure Records data.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the appropriate Q6 Camshaft Position Actuator Solenoid Valve.
2. Ignition ON, verify that a test lamp illuminates between the ignition circuit terminal 1 and ground.
瀚慖f the test lamp does not illuminate, test the circuit for a short to ground or an open/high resistance. If the circuit tests normal and the
ignition circuit fuse is open, test all the components connected to the ignition circuit and replace as necessary.
