Circuit/System Description

The clutch pressure control (PC) solenoid 2 is part of the control solenoid (w/body and TCM) valve assembly and is not serviced separately. The transmission control module (TCM) supplies 12 volts to the clutch PC solenoid 2 on the high side driver 2 circuit. The TCM control the PC solenoid 2 through the clutch PC solenoid 2 control circuit. The normally high clutch PC solenoid 2 flows fluid to the 3-5-R clutch when commanded OFF and exhausts fluid when commanded ON. The clutch PC 2 regulates the transmission fluid pressure to the 3-5-R clutch.

Conditions for Running the DTC

P0965

Start the ignition switch, run the engine.

P0966

P0967

Conditions for Setting the DTC

P0965

The TCM detects an internal electrical performance malfunction of the clutch PC solenoid control circuit and the actual 3-5-R clutch pressure does not equal the commanded 3-5-R clutch pressure for 4.4 seconds in the 5 seconds sample time.

P0966

The TCM detects an internal low voltage electrical malfunction of the clutch PC solenoid control circuit for 300 milliseconds in the 375 milliseconds sample time.

P0967

The TCM detects an internal high voltage electrical malfunction of the clutch PC solenoid control circuit for 300 milliseconds in the 375 milliseconds sample time.

Action Taken When the DTC Sets

Conditions for Clearing the DTC

Diagnostic Aids

When attempting to set DTCs, it may be helpful to ensure the TCM is warmed up and the transmission is operated in second gear long enough to ensure a 3°C (5°F) increase in TCM temperature. This will place the TCM under the optimal conditions to test DTCs.

Circuit/System Verification

Perform the following procedure to place the control solenoid (w/body and TCM) valve assembly under the optimal conditions to test solenoid electrical DTCs.

1. Ensure the transmission fluid temperature is between 50-80°C (122-176°F).
2. Operate the vehicle in second gear long enough to ensure at least a 3°C (5°F) rise in TCM substrate temperature and then operate the vehicle in third gear for 5 seconds.

Component Testing

The scan tool data parameter Clutch PC 2 Sol. CKT Status normally displays OK.

If the parameter displays Open/Short to Volts, Short to GND or if the DTC resets, perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection and if no concerns are found replace the control solenoid (w/body and TCM) valve assembly.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
