DTC P1760 OVERRUN CLUTCH SOLENOID VALVE

DTC P1760 OVERRUN CLUTCH SOLENOID VALVEPFP:31940
DescriptionECS004S9
The overrun clutch solenoid valve is activated by the TCM in
response to signals sent from the park/neutral position (PNP) switch,
overdrive control switch, vehicle speed and throttle position sensors.
The overrun clutch operation will then be controlled.
On Board Diagnosis LogicECS00CUJ
Possible CauseECS00CUK
Check the following items.

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

Overrun clutch solenoid valve
DTC Confirmation ProcedureECS00CUL
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch OFF and
wait at least 5 seconds before conducting the next test.
TESTING CONDITION:
Always drive vehicle on a level road to improve accuracy of test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON and select “DATA MONITOR” mode for
“A/T” with CONSULT-II.
2. Start engine.
3. Accelerate vehicle to a speed of more than 10 km/h (6 MPH)
with “D” position (O/D ON).
4. Release accelerator pedal completely with D position (O/D
OFF).
WITH GST
Follow the procedure “WITH CONSULT-II”.

TROUBLE DIAGNOSIS — INTRODUCTIONPFP:00000
IntroductionECS004TF
The TCM receives a signal from the vehicle speed sensor, throttle
position sensor or PNP switch and provides shift control or lock-up
control via A/T solenoid valves.
Input and output signals must always be correct and stable in the
operation of the A/T system. The A/T system must be in good oper-
ating condition and be free of valve seizure, solenoid valve malfunc-
tion, etc.
It is much more difficult to diagnose a problem that occurs intermit-
tently rather than continuously. Most intermittent problems are
caused by poor electric connections or improper wiring. In this case,
careful checking of suspected circuits may help prevent the replace-
ment of good parts.
A visual check only, may not find the cause of the problems. A road
test with CONSULT-II or a circuit tester connected should be per-
formed. Follow the “Work Flow”. Refer to AT- 6 1
.
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a drive ability complaint. The cus-
tomer can supply good information about such problems, especially
intermittent ones. Find out what symptoms are present and under
what conditions they occur. A “Diagnostic Worksheet” like the exam-
ple (AT- 5 8
) should be used.
Start your diagnosis by looking for “conventional” problems first. This
will help troubleshoot drive ability problems on an electronically con-
trolled engine vehicle.
Also check related Service bulletins for information.

Line Pressure TestECS004VT
LINE PRESSURE TEST PORTS
Location of line pressure test ports are shown in the illustration.

Always replace pressure plugs as they are self-sealing
bolts.
LINE PRESSURE TEST PROCEDURE
1. Check A/T fluid and engine oil levels. If necessary, add fluid or
oil.
2. Drive vehicle for approx. 10 minutes or until engine oil and ATF
reach operating temperature. Refer to AT- 1 7 , "
Changing A/T
Fluid" .
3. Install pressure gauge to corresponding line pressure port.
4. Set parking brake and block wheels.

Continue to depress brake pedal fully while line pressure
test is being performed at stall speed.
