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.
Possible CauseUCS005QR

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

Turbine revolution sensor (power train revolution sensor)
DTC Confirmation ProcedureUCS005QS
CAUTION:

Always drive vehicle at a safe speed.

Be careful not to rev engine into the red zone on the tachometer.

If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait
at least 10 seconds before continuing.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Start engine.
2. Select “DATA MONITOR” mode for “A/T” with CONSULT-II.
3. Touch “START”.
4. Drive vehicle under the following conditions for more than 5 sec-
onds.
SLCT LVR POSI: “D” position
VEHICLE SPEED: Higher than 40 km/h (25 MPH)
ENGINE SPEED: Higher than 1,500 rpm
THROTTLE POSI: Greater than 1.0/8 of the full throttle posi-
tion
5. If the check result is NG, go to AT-178, "
Diagnostic Procedure" .
WITHOUT CONSULT-II
1. Start engine.
2. Drive vehicle under the following conditions for more than 5 seconds.
Selector lever position: “D” position
Vehicle speed: Higher than 40 km/h (25 MPH)
Engine speed: Higher than 1,500 rpm
Throttle position: 1.0/8 of the full throttle position
3. Perform self-diagnosis. Refer to AT-90, "
Diagnostic Procedure Without CONSULT-II" .
4. If the check result is NG, go to AT-178, "
Diagnostic Procedure" .
