P0962

Diagnostic Chart:

Schematic:

The line pressure control (PC) solenoid is used to control main line pressure to the transaxle hydraulic system. The line PC solenoid is pulse with modulated (PWM) by the transaxle control module (TCM) whenever the engine is running. The TCM controls the line PC solenoid by pulse with modulating an internal driver that pulls the solenoid circuit to voltage. When the line PC solenoid is commanded Off, main line pressure is highest. During normal shift operation, the TCM will PWM the line PC solenoid in order to prevent clutch slip and harsh shifts. The line PC solenoid ground circuit is monitored for current flow. DTC P0962 sets if the TCM detects low current flow through the line PC solenoid.

DTC PARAMETERS
DTC P0962 sets if low current detected through the line pressure control solenoid and:
^ The engine is running
^ Transaxle Protection Mode is OFF
^ Condition exists for at least 12.5 seconds

The TCM will command Transaxle Protection Mode ON if this DTC is active.

DTC P0962 is a type A DTC.

DIAGNOSTIC AIDS
To locate an intermittent problem, use a scan tool to monitor Line PC Solenoid Actual Current with ignition ON, engine Off. Wiggling wires watching for a change on Line PC Solenoid Actual Current may locate the area where an open or high resistance in the wiring could lie.

Line pressure control solenoid current: 92-1356 mA

Line pressure control solenoid resistance: 3.8-8.3 ohm
