DTC TURBINE REVOLUTION SENSOR
DTC TURBINE REVOLUTION SENSOR
DescriptionINFOID:0000000001703313
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-III Reference Value in Data Monitor ModeINFOID:0000000001703314
Remarks: Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000001703315
• This is not an OBD-II self-diagnostic item.
• Diagnostic trouble code “TURBINE SENSOR” with CONSULT-III or 10th judgement flicker without CON-
SULT-III is detected when TCM does not receive the proper voltage signal from the sensor.
Possible CauseINFOID:0000000001703316
• Harness or connector
(The sensor circuit is open or shorted.)
• Turbine revolution sensor (power train revolution sensor)
DTC Confirmation ProcedureINFOID:0000000001703317
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-III
1. Start engine.
2. Select “DATA MONITOR” mode for “A/T” with CONSULT-III.
3. Touch “START”.
4. Drive vehicle under the following conditions for more than 5 seconds.
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 position
5. If the check result is NG, go to AT-160, "
Diagnosis Procedure" .
WITHOUT CONSULT-III
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-78, "
Diagnosis Procedure without CONSULT-III" .
4. If the check result is NG, go to AT-160, "
Diagnosis Procedure" .
Item name Condition Display value
TURBINE REV During driving (lock-up ON) Approximately matches the engine speed.

5. Check voltage between turbine revolution sensor (power train
revolution sensor) harness connector terminal and ground.
6. If OK, check harness for short to ground and short to power.
7. Reinstall any part removed.
OK or NG
OK >> GO TO 4.
NG - 1 >> Battery voltage is not supplied between terminals 1 and 3, terminals 1 and ground: GO TO 6.
NG - 2 >> Battery voltage is not supplied between terminals 1 and 3 only: GO TO 7.
4. CHECK HARNESS BETWEEN TCM AND TURBINE REVOLUTION SENSOR (POWER TRAIN REVOLU-
TION SENSOR)
1. Turn ignition switch OFF.
2. Disconnect the turbine revolution sensor (power train revolution sensor) harness connector.
3. Check continuity between TCM connector terminal and turbine
revolution sensor (power train revolution sensor) harness con-
nector terminal.
4. If OK, check harness for short to ground and short to power.
5. Reinstall any part removed.
OK or NG
OK >> GO TO 5.
NG >> Repair open circuit or short to ground or short to power in harness or connectors.
5.CHECK TCM
1. Check TCM input/output signal. Refer to AT-71, "
TCM Terminal and Reference Value" .
2. If NG, re-check TCM pin terminals for damage or loose connection with harness connector.
OK or NG
OK >> GO TO 8.
NG >> Repair or replace damaged parts.
6. CHECK HARNESS BETWEEN TCM AND TURBINE REVOLUTION SENSOR [(POWER TRAIN REVOLU-
TION SENSOR) POWER]
1. Turn ignition switch OFF.
2. Disconnect the turbine revolution sensor (power train revolution sensor) harness connector.
