OVERRUNCLUTCHSOLENOIDVALVE
OVERRUN CLUTCH SOLENOID VALVE
PFP:31940
DescriptionECS004U0
The overrun clutch solenoid valve is activated by the TCM in
response to signals sent from the inhibitor switch, overdrive control
switch, vehicle speed and throttle position sensors. The overrun
clutch operation will then be controlled.

Diagnostic ProcedureECS004UA
1.CHECK TCM POWER SOURCE
1. Turn ignition switch to “ON” position.
(Do not start engine.)
2. Check voltage between TCM terminals 10, 19, 28 and ground.
3. Turn ignition switch to “OFF” position.
4. Check voltage between TCM terminal 28 and ground.
OK or NG
OK >> GO TO 2
NG >> Check the following items:
lHarness for short or open between ignition switch and
TCM (Main harness)
lIgnition switch and fuse
Refer to “PG-2, "
POWER SUPPLY ROUTING"”,
“POWER SUPPLY ROUTING”.
2.CHECK A/T FLUID TEMPERATURE SENSOR WITH TERMINAL CORD ASSEMBLY
1. Turn ignition switch to “OFF” position.
2. Disconnect terminal cord assembly connector in engine compartment.
3. Check resistance between terminals 6 and 7 when A/T is cold.
4. Reinstall any part removed.
OK or NG
OK (With CONSULT-II)>>GO TO 3
OK (Without CONSULT-II)>>GO TO 4
NG >> 1. Remove oil pan.
2. Check the following items:
