DTC P0753 |
Shift solenoid A malfunction (electrical) |
---|---|
DETECTION CONDITION
|
• If TCM detects either of the following conditions, TCM determines that shift solenoid A circuit has a malfunction.
Diagnostic support note:
• This is a continuous monitor (CCM).
• The MIL illuminates if the TCM detects the above malfunction conditions during the first drive cycle.
• The PENDING CODE is available if the TCM detects the above malfunction condition during the first drive cycle.
• FREEZE FRAME DATA is available.
• The AT warning light illuminates.
• The DTC is stored in the TCM memory.
|
POSSIBLE CAUSE
|
• Shift solenoid A malfunction
• Short to ground in wiring harness between transaxle connector (primary) terminal A and TCM terminal AG
• Short to power supply in wiring harness between transaxle connector (primary) terminal A and TCM terminal AG
• Open circuit in wiring harness between shift solenoid A terminal B and transaxle connector (primary) terminal A
• Open circuit in wiring harness between transaxle connector (primary) terminal A and TCM terminal AG
• Open circuit in wiring harness between shift solenoid A terminal A and body ground
• Damaged connector between shift solenoid A and TCM
• TCM malfunction

STEP |
INSPECTION |
ACTION |
|
---|---|---|---|
1
|
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
• Has the FREEZE FRAME DATA been recorded?
|
Yes
|
Go to the next step.
|
No
|
Record the FREEZE FRAME DATA on the repair order, then go to the next step.
|

2
|
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
• Verify related Service Bulletins and/or on-line repair information availability.
• Is any related repair information available?
|
Yes
|
Perform repair or diagnosis according to the available repair information.
• If the vehicle is not repaired, go to the next step.
|
No
|
Go to the next step.
|
||
3
|
INSPECT TRANSAXLE CONNECTOR FOR POOR CONNECTION
• Turn the ignition switch to the LOCK position.
• Disconnect the transaxle connector (primary).
• Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
• Is the connection normal?
|
Yes
|
Go to the next step.
|
No
|
Repair or replace the connector and/or terminals, then go to Step 11.
|
||
4
|
INSPECT RESISTANCE
• Inspect the resistance between transaxle connector (primary) terminal A (transaxle case side) and body ground.
• Is the resistance within 1.0—4.2 ohms?
|
Yes
|
Go to Step 7.
|
No
|
Go to the next step.
|
||
5
|
INSPECT SHIFT SOLENOID A CONNECTOR FOR POOR CONNECTION
• Disconnect the shift solenoid A connector.
• Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
• Is the connection normal?
|
Yes
|
Go to the next step.
|
No
|
Repair or replace the connector and/or terminals, then go to Step 11.
|
||
6
|
INSPECT RESISTANCE
• Inspect the resistance between shift solenoid A terminals A and B (part-side).
• Is the resistance within 1.0—4.2 ohms?
|
Yes
|
Replace the solenoid wiring harness, then go to Step 11.
|
No
|
Verify shift solenoid A installation.
• If solenoid installed correctly, replace the solenoid, then go to Step 11.
|
||
7
|
INSPECT TCM CONNECTOR FOR POOR CONNECTION
• Disconnect the TCM connector.
• Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
• Is the connection normal?
|
Yes
|
Go to the next step.
|
No
|
Repair or replace the connector and/or terminals, then go to Step 11.
|
||
8
|
INSPECT TRANSAXLE CONNECTOR CIRCUIT FOR OPEN CIRCUIT
• Inspect for continuity between TCM terminal AG (wiring harness-side) and transaxle connector (primary) terminal A (wiring harness-side).
• Is there continuity between terminals?
|
Yes
|
Go to the next step.
|
No
|
Repair or replace the wiring harness, then go to Step 11.
|
||
9
|
INSPECT TRANSAXLE CONNECTOR CIRCUIT FOR SHORT TO POWER SUPPLY
• Turn the ignition switch to the ON position (engine off).
• Inspect the voltage at transaxle connector (primary) terminal A (wiring harness-side).
• Is the voltage 0 V?
|
Yes
|
Go to the next step.
|
No
|
Repair or replace the wiring harness, then go to Step 11.
|
||
10
|
INSPECT TCM CIRCUIT FOR SHORT TO GROUND
• Turn the ignition switch to the LOCK position.
• Inspect for continuity between TCM terminal AG (wiring harness-side) and body ground.
• Is there continuity?
|
Yes
|
Repair or replace the wiring harness, then go to Step 11.
|
No
|
Go to the next step.
|

|
VERIFY TROUBLESHOOTING OF DTC P0753 COMPLETED
• Make sure to reconnect all the disconnected connectors.
• Clear the DTC from the memory using the M-MDS.
• Drive the vehicle in D range and make sure that the gears shift smoothly from 1GR to 4GR.
• Are any DTCs present?
|
Yes
|
Replace the TCM, then go to the next step.
|
No
|
No concern is detected. Go to the next step.
|
||
12
|
VERIFY AFTER REPAIR PROCEDURE
• Perform the “After Repair Procedure”.
• Are any DTCs present?
|
Yes
|
Go to the applicable DTC inspection.
|
No
|
