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 A 
signal” circuit 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 A
1) Inspection transmission fluid temperature sensor A 

referring to “Transmission Fluid Temperature Sensor 
Removal and Installation”.

Is check result satisfactory?

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.

sensor signal or ground 
circuit is malfunction.

Go to Step 4.

4

Check visually input shaft speed sensor and clutch 
drum using mirror for following
• No damage
• No foreign material attached
• Correct installation

Are they in good condition?
