1. Many malfunctions in the electrical system are caused by poor harness and terminal condition. Faults can 

also be caused by interference from other electrical systems, and mechanical or chemical damage.  

2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, 

deterioration, or damage.  

3. Has a problem been found? 

YES  



Repair as necessary and then go to "VERIFICATION OF VEHICLE REPAIR" procedure.  

NO  



Go to "POWER SUPPLY CIRCUIT INSPECTION" procedure.  

POWER SUPPLY CIRCUIT INSPECTION 

1. Disconnect "A/T SOLENOID VALVE" connector.  

2. Measure voltage between terminal "6" of the sensor harness connector and chassis ground.  

3. Turn ignition switch OFF --> ON 

Specification: 12V is measured only for approx. 0.5 sec
