Revision: June 20062007 Versa
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:

Always drive vehicle at a safe speed.

3. Start engine.
4. Accelerate vehicle to a speed of more than 10 km/h (6 MPH)
with “D” position (OD ON).
5. Release accelerator pedal completely with “D” position (OD
OFF).
6. If the check result is NG, go to AT-163, "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-II”.
WITHOUT CONSULT-II
1. Start engine.
2. Drive vehicle under the following conditions:
Selector lever position: “D” position (OD ON)
Vehicle speed: Higher than 10 km/h (6 MPH)
3. Perform self-diagnosis. Refer to AT- 9 0 , "
Diagnostic Procedure Without CONSULT-II" .
4. If the check result is NG, go to AT-163, "

DTC VEHICLE SPEED SENSOR MTR
Revision: June 20062007 Versa
DTC VEHICLE SPEED SENSOR MTRPFP:24814
DescriptionUCS005Q9
The vehicle speed sensor·MTR is built into the speedometer assembly. The sensor functions as an auxiliary
device to the revolution sensor when it is malfunctioning. The TCM will then use a signal sent from the vehicle
speed sensor·MTR.
CONSULT-II Reference ValueUCS005QA
Remarks: Specification data are reference values.
On Board Diagnosis LogicUCS005QB

This is not an OBD-II self-diagnostic item.

Diagnostic trouble code “VHCL SPEED SEN-MTR” with CONSULT-II or 2nd judgement flicker without
CONSULT-II is detected when TCM does not receive the proper voltage signal from the sensor.
Possible CauseUCS005QC

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

Vehicle speed sensor
DTC Confirmation ProcedureUCS005QD
CAUTION:

Always drive vehicle at a safe speed.

If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait
at least 10 seconds before continuing.

WITH CONSULT-II
1. Turn ignition switch ON and select “DATA MONITOR” mode for
“A/T” with CONSULT-II.
2. Touch “START”.
3. Start engine and accelerate vehicle from 0 to 25 km/h (0 to 16
MPH).
4. If the check result is NG, go to AT-168, "
Diagnostic Procedure" .
WITHOUT CONSULT-II
1. Start engine.
2. Drive vehicle under the following conditions:
Selector lever position: “D” position
Vehicle speed: Higher than 25 km/h (16 MPH)
3. Perform self-diagnosis. Refer to AT-90, "
