DTC P1760 OVERRUN CLUTCH SOLENOID VALVE

DTC P1760 OVERRUN CLUTCH SOLENOID VALVEPFP:31940
DescriptionECS004S9
The overrun clutch solenoid valve is activated by the TCM in
response to signals sent from the park/neutral position (PNP) switch,
overdrive control switch, vehicle speed and throttle position sensors.
The overrun clutch operation will then be controlled.
On Board Diagnosis LogicECS00CUJ
Possible CauseECS00CUK
Check the following items.

Harness or connector
(The solenoid circuit is open or shorted.)

Overrun clutch solenoid valve
DTC Confirmation ProcedureECS00CUL
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch OFF and
wait at least 5 seconds before conducting the next test.
TESTING CONDITION:
Always drive vehicle on a level road to improve accuracy of test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON and select “DATA MONITOR” mode for
“A/T” with CONSULT-II.
2. Start engine.
3. Accelerate vehicle to a speed of more than 10 km/h (6 MPH)
with “D” position (OD ON).
4. Release accelerator pedal completely with D position (OD OFF).
WITH GST
Follow the procedure “WITH CONSULT-II”.
SCIA0718E
Diagnostic trouble code Malfunction is detected when... Check items (Possible cause)
: OVERRUN CLUTCH S/V
TCM detects an improper voltage drop
when it tries to operate the solenoid valve.
