Diagnostic Procedure
ECS0098F
1.
CHECK VALVE RESISTANCE
1.
Turn ignition switch to “OFF” position.
2.
Disconnect terminal cord assembly connector in engine compartment.
3.
Check resistance between terminal 2 and ground.
OK or NG
OK
>> GO TO 2
NG
>> 1. Remove control valve assembly. Refer to
"Control Valve Assembly and Accumulators"
.
2. Check the following items:
–
Shift solenoid valve A
Refer to
AT-177, "Component Inspection"
.
–
Harness of terminal cord assembly for short or open
2.
CHECK POWER SOURCE CIRCUIT
1.
Turn ignition switch to “OFF” position.
2.
Disconnect TCM harness connector.
3.
Check continuity between terminal 2 and TCM harness connector terminal 11.
If OK, check harness for short to ground and short to power.
4.
Reinstall any part removed.
OK or NG
OK
>> GO TO 3
NG
>> Repair open circuit or short to ground or short to power
in harness or connectors.
3.
CHECK DTC
Perform
AT-174, "DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE"
.
OK or NG
OK
>> INSPECTION END
NG
>> 1. Perform TCM input/output signal inspection.
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.

DTC P0755 SHIFT SOLENOID VALVE B
PFP:31940
Description
ECS0098H
Shift solenoid valves A and B are turned “ON” or “OFF” by the TCM
in response to signals sent from the PNP switch, vehicle speed and
throttle position sensors. Gears will then be shifted to the optimum
position.
