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 (PC) solenoid 4 is part of the control solenoid (w/body and TCM) valve assembly and is not serviced separately. The transmission control module (TCM) supplies 12 volts to the clutch PC solenoid 4
through the high side driver 1 circuit. The TCM controls the clutch PC solenoid 4 through the clutch PC solenoid 4 control circuit. The normally low clutch PC solenoid 4 flows fluid to the 1-3 clutch when commanded ON and exhausts
fluid when commanded OFF. The clutch PC 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. |
• | SS 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). |
P2714
The clutch PC solenoid 3 commanded pressure is greater than 1800 kpa (261 psi) for 4.5 seconds.
P2715
The clutch PC solenoid 3 commanded pressure is less than 5 kpa (1 psi) for 4.5 seconds.
Conditions for Setting the DTC
P2714 - Fail Case 1
The clutch PC solenoid 4 commanded pressure is 1800 kpa (261 psi) and the TFP switch 4 state is Low for 30 seconds.
P2714 - Fail Case 2
The clutch PC solenoid 4 commanded pressure is 1800 kpa (261 psi) and the TFP switch 4 state is Low for 0.5 seconds greater than 5 times during a key cycle.
P2715 - Fail Case 1
The clutch PC solenoid 4 commanded pressure is 5 kpa (1 psi) and the TFP switch 4 state is High for 36 seconds.
P2715 - Fail Case 2
The clutch PC solenoid 4 commanded pressure is 5 kpa (1 psi) and the TFP switch 4 state is High for 1.25 seconds greater than 5 times during a key cycle.
Action Taken When the DTC Sets
• | P2714 and P2715 are Type B DTCs. |
• | The TCM commands maximum line pressure. |
• | The TCM freezes transmission adaptive functions. |
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.

Control Solenoid Test Plate
Circuit/System Verification
- Perform the
Transmission Fluid Check
.
- Turn ON the ignition, with the engine OFF.
Important: Before clearing the DTC, use the scan tool in order to record the Freeze Frame and Failure Records.
- Record the DTC Freeze Frame and Failure Records.
- Clear the DTC.
- Operate the vehicle in drive with the calc. throttle position greater than 15 percent to obtain 72 km/h (45 mph) and achieve 4th gear. Stop the vehicle and turn Off the ignition for 30 seconds. Perform this maneuver 2 times.
⇒ | If the DTC resets, go to Circuit/System Testing. |
Circuit/System Testing
- Perform the
Line Pressure Check
.
⇒ | If the pressure is out of specification correct this concern first. |
- Perform the
Control Solenoid Valve and Transmission Control Module Assembly Inspection
.
⇒ | If a concern is found, repair or replace the control solenoid (w/body and TCM) valve assembly. |
- Perform the
Control Solenoid Valve and Transmission Control Module Assembly Solenoid Performance Test
.
⇒ | If the solenoid is found to be leaking or stuck closed, replace the control solenoid (w/body and TCM) valve assembly. |
- Inspect the control valve upper body assembly for sticking valves, damage, scored bores, or debris.
⇒ | If a concern if found in the valve body, repair or replace the valve body as necessary. |
