DTC Descriptors
DTC P2714
- Pressure Control Solenoid 4 - Stuck Off

DTC P2715
- Pressure Control 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 and reverse 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 and reverse clutch.

Conditions for Running the DTC

* Shift solenoid valve 1 is not in a transition state.
* The transmission line pressure is greater than 325 kPa (47 psi).
* Propulsion system is active.

P2714

The clutch pressure control solenoid 4 commanded pressure is greater than 1800 kPa (261 psi) for 5 seconds.

P2715

The clutch pressure control solenoid 4 commanded pressure is less than 5 kPa (1 psi) for 5 seconds.

Conditions for Setting the DTC

P2714 - Condition 1

The clutch pressure control solenoid 4 commanded pressure is 1800 kPa (261 psi) and the transmission fluid pressure switch 4 state is Low for 30 seconds.

P2714 - Condition 2

The clutch pressure control solenoid 4 commanded pressure is 1800 kPa (261 psi) and the transmission fluid pressure switch 4 state is Low for 2 seconds greater than 5 times during a key cycle.

P2715 - Condition 1

The clutch pressure control solenoid 4 commanded pressure is 5 kPa (1 psi) and the transmission fluid pressure switch 4 state is High for 36 seconds.

P2715 - Condition 2

The clutch pressure control solenoid 4 commanded pressure is 5 kPa (1 psi) and the transmission fluid pressure switch 4 state is High for 2 seconds greater than 5 times during a key cycle.

Action Taken When the DTC Sets

* P2714 and P2715 are Type B DTCs.
* The transmission control module commands 450 kPa (65 psi) line pressure.
* The transmission control module freezes transmission adaptive functions.
* The driver information center may display ENGINE NOT AVAILABLE SERVICE SOON.

Conditions for Clearing the DIC/DTC

P2714 and P2715 are Type B DTCs.

Diagnostic Aids

When attempting to set transmission performance DTCs, observe the Freeze Frame and Failure Records to assist in duplicating the failure conditions.
