DTC Descriptors
DTC P2714
- Clutch Pressure Control (PC) Solenoid 4 - Stuck Off
DTC P2715
- Clutch Pressure Control (PC) Solenoid 4 - Stuck On
Circuit/System Description
The clutch pressure control (PC) solenoid 4 is part of the control solenoid valve assembly, which has no serviceable parts. The PC solenoid 4
regulates transmission fluid pressure to the 2-6 clutch regulator valve which controls pressure to the 2-6 clutch. The TCM calculates gear ratio
based on the RPM signals from the input speed sensor (ISS) and the output speed sensor (OSS). The TCM compares the expected transmission gear
ratio to the calculated gear ratio for each commanded gear.
Conditions for Running the DTC
P2714
* DTCs P0716, P0717, P0722, P0723, P1825, or P1915 are not set.
* The transmission input shaft speed is greater than 60 RPM.
* 2-6 clutch is commanded ON.
P2715
* DTCs P0716, P0717, P0722, P0723, P1825, or P1915 are not set.
* The transmission output shaft speed is greater than 200 RPM.
* 2-6 clutch is commanded OFF.
Conditions for Setting the DTC
P2714
The TCM detects an incorrect on-coming clutch gear ratio, or flare, when the 2-6 clutch is commanded ON for 0.5 seconds and the transmission
input shaft speed is greater than 75 RPM from the anticipated input shaft speed.
P2715
The TCM detects an incorrect off-going clutch gear ratio, or tie-up, when the 2-6 clutch is commanded OFF for 0.5 seconds and the transmission
input shaft speed is greater than 40 RPM from the anticipated input shaft speed.
