DTC Descriptors
DTC P2714
- Pressure Control (PC) Solenoid 4 - Stuck Off
DTC P2715
- Pressure Control (PC) Solenoid 4 - Stuck On
Circuit/System Description
The clutch pressure control solenoid 4 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 4 through the high side driver 1 circuit. The transmission control module controls
the clutch pressure control solenoid 4 through the clutch pressure control solenoid 4 control circuit. The normally low clutch pressure control
solenoid 4 flows fluid to the 1-3 clutch when commanded ON and exhausts fluid when commanded OFF. The clutch pressure control solenoid 4
regulates the transmission fluid pressure to the 1-3 clutch.
Conditions for Running the DTC
* The engine run time is greater than 1 second.
* Shift solenoid valve 1 is not in a transition state.
* The transmission line pressure is greater than 370 kPa (54 psi) and not fluctuating by greater than 30 kPa (4 psi).
