DTC P1760 OVERRUN CLUTCH SOLENOID VALVE
DescriptionINFOID:0000000001694378
The overrun clutch solenoid valve is activated by the TCM in response to signals sent from the PNP switch,
overdrive control switch, vehicle speed and ECM (throttle opening). The overrun clutch operation will then be
controlled.
CONSULT-III Reference Value in Data Monitor ModeINFOID:0000000001694379
Remarks: Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000001694380
 This is an OBD self-diagnostic item.
 Diagnostic trouble code “P1760 OVERRUN CLUTCH S/V” with CONSULT-III or 6th judgement flicker with-
out CONSULT-III is detected when TCM detects an improper voltage drop when it tries to operate solenoid
valve.
Possible CauseINFOID:0000000001694381
 Harness or connector
(The solenoid circuit is open or shorted.)

REFERENCE VALUES
NOTICE:
1. The CONSULT-III electrically displays shift timing and lock-up timing (that is, operation timing of each
solenoid).
Check for time difference between actual shift timing and the CONSULT-III display. If the difference is
noticeable, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical
parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) displayed on CONSULT-III and that indicated in Service Man-
ual may differ slightly. This occurs because of the following reasons:
- Actual shift schedule has more or less tolerance or allowance,
- Shift schedule indicated in Service Manual refers to the point where shifts start, and
- Gear position displayed on CONSULT-III indicates the point where shifts are completed.
3. Shift solenoid valve “A” or “B” is displayed on CONSULT-III at the start of shifting. Gear position is dis-
played upon completion of shifting (which is computed by TCM).

If non-standard solenoid signal is sent to TCM, torque converter clutch solenoid valve is turned OFF to release
lock-up.
Overrun Clutch Solenoid Valve
If non-standard solenoid signal is sent to TCM, overrun clutch solenoid valve is turned OFF to engage overrun
clutch. This will result in more effective engine brake during deceleration.
