Circuit/System Description
|
The camshaft position (CMP) actuator system enables the engine control module (ECM) to change the timing of the camshafts while the engine is operating. The CMP actuator solenoid signal from the ECM is pulse width modulated (PWM). The ECM controls the CMP actuator solenoid duty cycle by controlling the amount of solenoid ON time. The CMP actuator solenoid controls the advance or the retard of each camshaft. The CMP actuator controls the oil forward or backward flow which applies the pressure that changes the setting of the camshaft forward or backward.
Ignition voltage is supplied directly to the CMP actuator solenoid. The ECM controls the solenoid by grounding the control circuit with a solid state device called a driver. The driver is equipped with a feedback circuit that is pulled-up to a voltage. The ECM can determine if the control circuit is open, shorted to ground, or shorted to a voltage by monitoring the feedback voltage.
|
Conditions for Running the DTC
|
|
•
|
The engine speed is greater than 80 RPM.
|
|
•
|
The ignition voltage is between 10-18 V.
|
|
•
|
The ECM has commanded the Camshaft Position Actuator Solenoid Valve ON and OFF at least once during the ignition cycle.
|
|
•
|
DTCs P0010, P0013, P2088, P2089, P2090, and P2091 run continuously once the above conditions are met for greater than 1 second.
|
|
Conditions for Setting the DTC
|
P0010 or P0013
The ECM detects an open 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.
P2088 or P2090
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 or P2091
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, P2088, P2089, P2090 and P2091 are type B DTCs.
|
Conditions for Clearing the MIL/DTC
|
DTCs P0010, P0013, P2088, P2089, P2090 and P2091 are type B DTCs.
If the condition is intermittent, move the related harnesses and connectors, with the engine operating, while monitoring the scan tool 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, P2088, P2089, P2090, or P2091 should not set.
|
|
2.
|
Increase the engine speed to 2,000 RPM. Command the appropriate Camshaft Position Actuator Solenoid Valve to 25 percent. The Desired Intake/Exhaust Camshaft Position parameter should match the Intake/Exhaust Camshaft Position parameter.
|
|
3.
|
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.
|
|
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 A and ground.
|
|
3.
|
If 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.
|
|
4.
|
Connect a DMM, set on the diode setting, between the control circuit terminal B and ground. The voltage should be greater than 2 V.
|
|
5.
|
If 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.
|
|
6.
|
If less than the specified value, test the control circuit for a short to ground. If the circuit tests normal, replace the K20 Engine Control Module.
|
|
7.
|
Command the Camshaft Position Actuator Solenoid Valve ON and OFF with a scan tool. The DMM should transition from greater than 2 V when commanded OFF to less than 1 V, when commanded ON.
|
|
8.
|
If the circuit voltage does not correspond to the specified values, replace the K20 Engine Control Module.
|
|
9.
|
If all circuits/connections test normal, test or replace the appropriate Q6 Camshaft Position Actuator Solenoid Valve.
|
|
1.
|
Ignition OFF, disconnect the harness connector at the appropriate Q6 Camshaft Position Actuator Solenoid Valve.
|
|
2.
|
Test for 7-12 Ω between the control terminal B and the ignition terminal A of the Q6 Camshaft Position Actuator Solenoid Valve.
|
|
3.
|
If not within the specified range, replace the Q6 Camshaft Position Actuator Solenoid Valve.
|
|
4.
|
Test for infinite resistance between each terminal and the Q6 Camshaft Position Actuator Solenoid Valve housing.
|
|
5.
|
If not within the specified range, replace the Q6 Camshaft Position Actuator Solenoid Valve.
|
Perform the
Diagnostic Repair Verification
after completing the diagnostic procedure.
