Diagnostic Fault Information
Typical Scan Tool Data
Circuit/System Description
The clutch pressure control (PC) solenoid 4 is part of the control solenoid valve assembly which has no serviceable parts. The normally low PC
solenoid 4 regulates and directs oil pressure to the 2-6 clutch regulator valve. Increasing PC solenoid 4 pressure, increases pressure to the 2-6 clutch
regulator valve. The TCM varies the current to the PC solenoid 4 through a low side driver. Increasing the current to PC solenoid 4 increases oil
pressure by closing OFF the solenoid exhaust port. Decreasing the current to PC solenoid 4 decreases oil pressure by opening the exhaust port. PC
solenoid 4 power is supplied by the TCM through a high side driver (HSD). The HSD protects the circuit and components from excessive current
flow. If excessive current flow is detected, the HSD will turn OFF. When the fault is corrected the HSD will reset.
Conditions for Running the DTC
P2719, P2720, or P2721
* DTCs P2719, P2720, or P2721 have not set this ignition.
* The ignition voltage is 8.6 volts or greater.
* The engine speed is 500 RPM or greater, for 5 seconds.
* The clutch PC solenoid 4 is commanded ON.
Conditions for Setting the DTC
P2719
The TCM detects an internal electrical malfunction on the clutch PC solenoid 4 control circuit where the measured PC solenoid 4 current does not
equal the commanded clutch PC solenoid 4 current for 5 seconds.
