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

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.
CONSULT-II Reference ValueUCS005QP
Remarks: Specification data are reference values.
On Board Diagnosis LogicUCS005QQ

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

Diagnostic trouble code “TURBINE SENSOR” with CONSULT-II or 10th judgement flicker without CON-
SULT-II is detected when TCM does not receive the proper voltage signal from the sensor.
