DTC P0750 SHIFT SOLENOID VALVE A
Diagnostic Procedure
ECS004S0
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 toAT-454,
"REMOVAL".
2. Check the following items:
–Shift solenoid valve A
Refer to “Component Inspection”,AT-197, "
Compo-
nent 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 Diagnostic Trouble Code (DTC) confirmation procedure,AT- 1 9 4 , "
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. Resistance : 20 - 30W

DTC P0755 SHIFT SOLENOID VALVE B
PFP:31940
DescriptionECS004S2
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.

DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCE-
DURE” has been previously conducted, always turn ignition
switch “OFF” and wait at least 5 seconds before conducting the
next test.
After the repair, perform the following procedure to confirm the mal-
function is eliminated.
With CONSULT-II
1. Turn ignition switch “ON” and select “DATA MONITOR” mode for
“ENGINE” with CONSULT-II.
2. Start engine.
3. Drive vehicle in D position and allow the transmission to shift 1
®2®3 (“GEAR”).
With GST
Follow the procedure “With CONSULT-II”.
