P0762
Diagnostic Chart:
Schematic:
Shift solenoid (3) is turned electrically On/hydraulically Open during 1st, 2nd, 3rd, and reverse gear operation. Shift solenoid 3 is turned electrically OFF/hydraulically CLOSED during 4th and 5th gear operation. The transaxle control module (TCM) controls shift solenoid 3 by controlling an internal driver that pulls the solenoid circuit to voltage. During normal 4th gear shift operation, the TCM will turn OFF shift solenoid 3 and keep it OFF until downshift to 3rd or lower gear occurs. The TCM will turn OFF shift solenoid 3 and keep it OFF until a downshift to 3rd or lower gear occurs. The TCM monitors the actual gear ratio for each gear commanded. DTC P0762 sets when the gear ratio when 4th gear is commanded is 1.89:1, or the gear ratio when 5th is commanded is 1.45:1, indicating that shift solenoid 3 is stuck open, or that the U2 shift valve (2) is stuck in the valvebody (1).
DTC PARAMETERS
DTC P0761 will set if 5th gear is selected, and current gear ratio, is 20% less than expected gear ratio or 4th gear is selected, and current gear ratio is the same as 3rd gear and:
^ Ignition voltage is at least 10.5 volts
^ Engine speed is at least 400 RPM
^ Transaxle oil temperature is greater than 20°C
^ A forward gear has been selected for at least 8 seconds
^ Condition exists for 12 seconds
The TCM will command Transaxle Protection Mode ON if this DTC is active.
DTC P0762 is a type A DTC.
DIAGNOSTIC AIDS
IMPORTANT: If DTC P0717, P0722, or P0980 is set, diagnose that DTC first.
Shift Solenoid 3 may produce a louder click noise when turned OFF than when turned ON. This is normal, and is not reason to replace shift solenoid 3.
If shift solenoid 3 is stuck open, or if the U2 shift valve is stuck outward, harsh 3-4 upshifts, 1.89:1 ratio 4th gear, and 1.45:1 ratio in 5th gear may result. DTCs P0734, P0735, and P1719 may also set.
Shift solenoid 3 resistance: 8.4-22.6 ohms.
