DTC Descriptor
DTC P0965
- Pressure Control Solenoid 2 System Performance
DTC P0966
- Pressure Control Solenoid 2 Control Circuit Low Voltage
DTC P0967
- Pressure Control Solenoid 2 Control Circuit High Voltage
Diagnostic Fault Information
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 flows fluid 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.

Circuit/System Verification
1. Vehicle ON, verify the transmission fluid temperature is between 50-80°C (122-176°F).
2. 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.
