power supply short
1) Cool down A/T fluid temperature under ambient 

temperature.

2) Connect TCM connectors to TCM with ignition switch 

OFF.

3) Turn ignition switch ON.
4) Measure voltage between terminal “E92-11” of TCM 

connector and ground.

Is it 4.89 V or more?

Transmission fluid 
temperature sensor 
circuit is shorted to 
power supply circuit. If 
circuit is OK, go to Step 
4.

Intermittent trouble or 
faulty TCM. Check for 
intermittent trouble 
referring to “Intermittent 
and Poor Connection 
Inspection in Section 
00”. If OK, substitute a 
known-good TCM and 
recheck.

4

Inspection transmission fluid temperature sensor
1) Inspection transmission fluid temperature sensor 

referring to “Transmission Fluid Temperature Sensor 
Inspection”.

Is result satisfactory?

Intermittent trouble or 
faulty TCM. Check for 
intermittent trouble 
referring to “Intermittent
