DTC P0750 SHIFT SOLENOID VALVE A

Description

INFOID:0000000001694356

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 ECM (throttle opening). Gears will then be shifted to the optimum position.

CONSULT-III Reference Value in Data Monitor Mode

INFOID:0000000001694357

Remarks: Specification data are reference values.

On Board Diagnosis Logic

INFOID:0000000001694358

• This is an OBD self-diagnostic item.
• Diagnostic trouble code “P0750 SHIFT SOLENOID/V A” with CONSULT-III or 4th judgement flicker without

CONSULT-III is detected when TCM detects an improper voltage drop when it tries to operate the solenoid
valve.

Possible Cause

INFOID:0000000001694359

• Harness or connector

(The solenoid circuit is open or shorted.)

• Shift solenoid valve A

DTC Confirmation Procedure

INFOID:0000000001694360

CAUTION:

• Always drive vehicle at a safe speed.
• If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait at

least 10 seconds before continuing.

After the repair, perform the following procedure to confirm the malfunction is eliminated.

 WITH CONSULT-III

1.

Turn ignition switch ON and select “DATA MONITOR” mode for “A/T” with CONSULT-III.

2.

Touch “START”.

3.

Start engine.

4.

Drive vehicle in “D” position and allow the transaxle to shift 1 

→

 2 (“GEAR”).

5.

If the check result is NG, go to 

TM-85, "Diagnosis Procedure"

.

 WITH GST

Follow the procedure “WITH CONSULT-III”.

 WITHOUT CONSULT-III

1.

Start engine.

2.

Drive vehicle in D

1

→

 D

2

 position.

3.

Perform self-diagnosis. Refer to 

TM-38, "Diagnosis Procedure without CONSULT-III"

.

4.

If the check result is NG, go to 

TM-85, "Diagnosis Procedure"

.
