DTC P1760 OVERRUN CLUTCH SOLENOID VALVEPFP:31940
DescriptionUCS005Q1
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-II Reference ValueUCS005Q2
On Board Diagnosis LogicUCS005Q3
This is an OBD-II self-diagnostic item.
Diagnostic trouble code “P1760 OVERRUN CLUTCH S/V” with CONSULT-II or 6th judgement flicker with-
out CONSULT-II is detected when TCM detects an improper voltage drop when it tries to operate solenoid
valve.
Possible CauseUCS005Q4
Harness or connector
(The solenoid circuit is open or shorted.)
Overrun clutch solenoid valve
DTC Confirmation ProcedureUCS005Q5
CAUTION:

DTC TURBINE REVOLUTION SENSOR
Revision: June 20062007 Versa
DTC TURBINE REVOLUTION SENSORPFP:31935
DescriptionUCS005QO
The turbine revolution sensor (power train revolution sensor) detects forward clutch drum rpm (revolutions per
minute). It is located on the input side of the automatic 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 result, optimal shift timing during deceleration and shift quality can be improved.
