DTC Descriptor
DTC P0965
- Clutch Pressure Control (PC) Solenoid 2 System Performance
DTC P0966
- Clutch Pressure Control (PC) Solenoid 2 Control Circuit Low Voltage
DTC P0967
- Clutch Pressure Control (PC) Solenoid 2 Control Circuit High Voltage
Diagnostic Fault Information
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 controls 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
* The engine run time is greater than 5 seconds.
* The clutch PC solenoid 2 is commanded ON.
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 300 milliseconds.
P0966
The TCM detects an internal low voltage electrical malfunction of the clutch PC solenoid control circuit for 300 milliseconds.
P0967
The TCM detects an internal high voltage electrical malfunction of the clutch PC solenoid control circuit for 300 milliseconds.
Action Taken When the DTC Sets
* DTCs P0965, P0966, and P0967 are Type A DTCs.
* The TCM defaults the transmission to a limited shift pattern utilizing 2 forward gears and reverse based on the fault detected.
* The TCM commands maximum line pressure.
* The TCM freezes transmission adaptive functions.
Conditions for Clearing the DTC
DTCs P0965, P0966, and P0967 are Type A DTCs.
Diagnostic Aids
When attempting to set solenoid electrical DTCs, it may be helpful to make sure the TCM is warmed up and the transmission is operated in second gear long enough to make sure a 3°C (5°F) increase in TCM temperature. This will place the TCM under the optimal conditions to test solenoid electrical 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 make sure 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 (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
Important: Always perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
Replace the control solenoid (w/body and TCM) valve assembly. Refer to Control Module References (Programming and Relearning) for replacement, setup, and programming.
