DTC P0750 SHIFT SOLENOID VALVE A
Diagnostic Procedure
ECS007ND
1.
CHECK GROUND CIRCUIT
1.
Turn ignition switch to OFF position.
2.
Disconnect terminal cord assembly connector in engine compartment.
3.
Check resistance between terminal cord assembly connector
E72 terminal 2 and ground.
Is resistance approx. 20 - 40
Ω?
Yes
>> GO TO 2.
No
>> 1. Remove control valve assembly.
Refer to
.
2. Check the following items:
–
Shift solenoid valve A
Refer to
AT-315, "SHIFT SOLENOID VALVE A"
–
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 resistance between terminal cord assembly connector E72 terminal 2 and TCM harness connector
M77 terminal 11. Refer to wiring diagram.
If OK, check harness for short to ground and short to power.
Is resistance approx. 0
Ω?
Yes
>> GO TO 3.
No
>> 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. Refer to
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.

Description
ECS007NF
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.

Remarks: Specification data are reference values.
ON BOARD DIAGNOSIS LOGIC
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.
