Circuit/System Description

The clutch pressure control (PC) solenoid 2 is part of the control solenoid (w/body and TCM) valve assembly. The control solenoid (w/body and TCM) valve assembly has no seviceable parts. The transmission control module (TCM) supplies 12 volts to the clutch PC solenoid 2 on the high side driver 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. This allows the clutch PC solenoid 2 to regulate the transmission fluid pressure to the 3-5-R clutch.

Conditions for Running the DTC

P0965

P0966

P0967

Conditions for Setting the DTC

P0965

The TCM detects an internal electrical performance malfunction of the clutch PC solenoid 2 control circuit where the actual 3-5-R clutch pressure does not equal the commanded 3-5-R clutch pressure for 10.5 seconds.

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.

Diagnostic Aids

P0965

DTC P0965 detects an invalid voltage in the 3-5-R clutch variable bleed solenoid (VBS) control circuit.

P0966

DTC P0966 detects a continuous short to ground in the 3-5-R clutch VBS control circuit.

P0967

DTC P0967 detects a continuous open or short to voltage in the 3-5-R clutch VBS control circuit.

When attempting to set solenoid electrical 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 solenoid electrical DTCs.

Circuit/System Verification

1. Ensure the transmission fluid temperature is between 50-80°C (122-176°F).
2. Perform the Control Solenoid Valve and Transmission Control Module Assembly Cleaning procedure to dislodge debris and free up valves.
3. Operate the vehicle in 2nd gear long enough to ensure at least a 3°C (5°F) rise in TCM temperature and then operate the vehicle in 3rd gear for 5 seconds.
4. Verify that the scan tool data parameter, Clutch PC 2 Sol. CKT Status, displays OK.

⇒	If not the specified value, replace the control solenoid (w/body and TCM) valve assembly.

5. 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.
