DTC P1760 OVERRUN CLUTCH SOLENOID VALVE
Description INFOID:0000000004305427
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 (throt tle opening). The overrun clutch operation will then be
controlled.
CONSULT-III Reference Val ue in Data Monitor Mode INFOID:0000000004305428

• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P1760 OVERRUN CLUTCH S/V” wit h CONSULT-III or 6th judgement flicker with-
out CONSULT-III is detected when TCM detects an im proper voltage drop when it tries to operate solenoid
valve.
Possible Cause INFOID:0000000004305430
• Harness or connector (The solenoid circuit is open or shorted.)
• Overrun clutch solenoid valve
DTC Confirmation Procedure INFOID:0000000004305431

DTC TURBINE REVOLUTION SENSOR
Description INFOID:0000000004305450
The turbine revolution sensor (power train revolution s ensor) detects forward clutch drum rpm (revolutions per
minute). It is located on the input side of the automat ic transaxle. The vehicle speed sensor A/T (Revolution
sensor) is located on the output side of the automatic transaxle. With the two sensors, input and output rpms
are accurately detected. As a resu lt, optimal shift timing during deceleration and shift quality can be improved.
