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.

3. Connect a DMM, set on the diode setting, between the control circuit terminal 2 and ground. The voltage should be greater than 2 V.

瀚慖f the DMM displays OL, test the control circuit for a short to voltage or an open/high resistance. If the circuit/connections test normal,

replace the K20 Engine Control Module.

瀚慖f less than the specified value, test the control circuit for a short to ground. If the circuit tests normal, replace the K20 Engine Control
