P0750 SHIFT SOLENOID A
DescriptionINFOID:0000000005928186
Shift solenoid valves A and B are turned ON or OFF by the TCM in response to signals sent from the transmis-
sion range switch, vehicle speed and ECM (throttle opening) . Gears will then be shifted to the optimum posi-
tion.

• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0750 SHIFT SOLENOID A” wi th 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 CauseINFOID:0000000005928189

DTC Confirmation ProcedureINFOID:0000000005928190
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 proc edure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON and select “DATA MONI TOR” mode for “TRANSMISSION” 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 AT-140, "
Diagnosis Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-III”.
WITHOUT CONSULT-III
1. Start engine.
2. Drive vehicle in D
1→ D2 position.
3. Perform self-diagnosis. Refer to AT-82, "
Diagnosis Procedure without CONSULT-III" .
4. If the check result is NG, go to AT-140, "
