DTC P1760 OVERRUN CLUTCH SOLENOID VALVE
Description INFOID:0000000004305427
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 (throt tle opening). The overrun clutch operation will then be
controlled.
CONSULT-III Reference Val ue in Data Monitor Mode INFOID:0000000004305428
On Board Diagnosis Logic INFOID:0000000004305429
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P1760 OVERRUN CLUTCH S/V” wit h CONSULT-III or 6th judgement flicker with-
out CONSULT-III is detected when TCM detects an im proper voltage drop when it tries to operate solenoid
valve.
Possible Cause INFOID:0000000004305430
• Harness or connector (The solenoid circuit is open or shorted.)
• Overrun clutch solenoid valve
DTC Confirmation Procedure INFOID:0000000004305431
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.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON and select “DATA MO NITOR” mode for “TRANSMISSION” with CONSULT-III.
2. Touch “START”.
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-151, " Diagnosis Procedure " .
WITH GST
Follow the procedure “WITH CONSULT-III”.
WITHOUT CONSULT-III
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-83, " Diagnosis Procedure without CONSULT-III " .
4. If the check result is NG, go to AT-151, " Diagnosis Procedure " .

DTC TURBINE REVOLUTION SENSOR
Description INFOID:0000000004305450
The turbine revolution sensor (power train revolution s ensor) detects forward clutch drum rpm (revolutions per
minute). It is located on the input side of the automat ic 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 resu lt, optimal shift timing during deceleration and shift quality can be improved.
CONSULT-III Reference Val ue in Data Monitor Mode INFOID:0000000004305451
Remarks: Specification data are reference values.
On Board Diagnosis Logic INFOID:0000000004305452
• This is not an OBD-II self-diagnostic item.
• Diagnostic trouble code “TURBINE SENSOR” with CO NSULT-III or 10th judgement flicker without CON-
SULT-III is detected when TCM does not receiv e the proper voltage signal from the sensor.
Possible Cause INFOID:0000000004305453
• Harness or connector (The sensor circuit is open or shorted.)
• Turbine revolution sensor (power train revolution sensor)
DTC Confirmation Procedure INFOID:0000000004305454
