Clutch Pressure Control Solenoid 2 Control	P0966	P0967	P0967	P0965

Circuit/System Description

The transmission control module supplies 12 volts to the clutch pressure control solenoid 2 on the high side driver 2 circuit. The transmission control module controls the pressure control solenoid 2 through the clutch pressure control solenoid 2 control circuit. The normally high clutch pressure control solenoid 2 directs fluid flow to the variable high and 2-3-4 clutch assembly and drive motor 2 when commanded ON. The clutch pressure control solenoid 2 is part of the control solenoid valve assembly and is not serviced separately.

Conditions for Running the DTC

The system voltage is 11-16 V.

Conditions for Setting the DTC

P0965

The transmission control module detects an internal electrical performance malfunction of the clutch pressure control solenoid control circuit for 5 seconds.

P0966

The transmission control module detects an internal low voltage electrical malfunction of the clutch pressure control solenoid control circuit for 1 second.

P0967

The transmission control module detects an internal high voltage electrical malfunction of the clutch pressure control solenoid control circuit for 1 second.

Action Taken When the DTC Sets

•	DTC P0965 is a Type B DTC.

•	DTCs P0966 and P0967 are Type A DTCs.

Conditions for Clearing the DTC

•	DTC P0965 is a Type B DTC.

•	DTCs P0966 and P0967 are Type A DTCs.

Circuit/System Verification

Vehicle ON, verify the transmission fluid temperature is between 50-80°C (122-176°F).
Drive the vehicle in order to obtain dual motor or dual motor and ICE mode, observe the scan tool Pressure Control Solenoid Valve 2 Performance Test Status parameters. The readings should display OK.

⇒	If the reading is not within the specified range, replace the Q8 control solenoid valve assembly.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
