DTC Descriptors

DTC P0796

- Pressure Control (PC) Solenoid 3 - Stuck Off

DTC P0797

- Pressure Control (PC) Solenoid 3 - Stuck On

Circuit/System Description

The clutch pressure control solenoid 3 is part of the control solenoid valve assembly and is not serviced separately. The transmission control

module supplies 12 volts to the clutch pressure control solenoid 3 on the high side driver 1 circuit. The transmission control module controls the

clutch pressure control solenoid 3 through the clutch pressure control solenoid 3 control circuit. The normally high clutch pressure control solenoid

3 controls fluid to hybrid low, 1-2 and the 4th clutch assemblies when commanded ON and exhausts fluid when commanded OFF. The clutch

pressure control solenoid 3 regulates the transmission fluid pressure to the hybrid low, 1-2 and the 4th clutch assemblies.

Conditions for Running the DTC

P0796 or P0797
