DTC Descriptors
DTC P0776
- Pressure Control (PC) Solenoid 2 - Stuck OFF
DTC P0777
- Pressure Control (PC) Solenoid 2 - Stuck ON
Circuit/System Description
The clutch pressure control solenoid 2 is part of the control solenoid valve assembly and is not serviced separately. The clutch pressure control
solenoid 2 controls transmission fluid pressure to the hybrid direct, 2-3-4 clutch regulator valve. The transmission control module monitors the
transmission fluid pressure switch 3 state, in order to determine function of the clutch pressure control solenoid 2 and the hybrid direct, 2-3-4 clutch
regulator valve. When the clutch pressure control solenoid 2 is commanded ON, the transmission fluid pressure switch 3 state should be High.
When the clutch pressure control solenoid 2 is commanded Off, the transmission fluid pressure switch 3 parameter state should be Low.
Conditions for Running the DTC
P0776 or P0777
* The engine run time is greater than 1 second.
* Shift solenoid valve 1 is not in a transition state.
