^ DTC P0967 Clutch Pressure Control (PC) Solenoid 2 Control Circuit High Voltage
Diagnostic Fault Information
Important: Always perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Initial Inspection and Diagnostic Overview
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
^ the engine run time is greater than 5 seconds.
^ The clutch PC solenoid 2 is commanded ON.
Conditions for Setting the DTC
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.
DTC P0966
The TCM detects an internal low voltage electrical malfunction of the clutch PC solenoid control circuit for 300 milliseconds.
DTC 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. Refer to Diagnostic Trouble Code (DTC) Type Definitions and Diagnostic Trouble Code (DTC) List/Type. Diagnostic Trouble Code Descriptions Diagnostic Trouble Code Descriptions
^ The TCM defaults the transmission to a limited shift pattern utilizing two 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. Refer to Diagnostic Trouble Code (DTC) Type Definitions and Diagnostic Trouble Code (DTC) List/Type. Diagnostic Trouble Code Descriptions Diagnostic Trouble Code Descriptions
Diagnostic Aids
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.
