  3. Check for proper connection to transmission fluid temperature sensor at terminal "E92-11" and "E92-12".
  4. If OK, check continuity between terminal "E92-11" and "E92-12" of disconnected harness side TCM connector.

Is continuity indicated? 		 Go to Step 3. Transmission fluid temperature sensor signal or ground, circuit is open circuit. If circuit is OK, go to Step 4.
3  Check transmission fluid temperature sensor circuit for IG 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 signal circuit shorted to power supply circuit. If circuit is OK, go to Step 4. Intermittent trouble or faulty TCM. Check for intermittent trouble by referring to INTERMITTENT AND POOR CONNECTION INSPECTION . If OK, substitute a known-good TCM and recheck.
4  Inspection transmission fluid temperature sensor 
  1. Inspection transmission fluid temperature sensor by referring toTRANSMISSION FLUID TEMPERATURE SENSOR REMOVAL AND INSTALLATION .

Is check result satisfactory? 		 Intermittent trouble or faulty TCM. Check for intermittent trouble by referring to INTERMITTENT AND POOR CONNECTION INSPECTION . If OK, substitute a known-good TCM and recheck. Replace valve body harness including transmission fluid temperature sensor by referring to TRANSMISSION FLUID TEMPERATURE SENSOR REMOVAL AND INSTALLATION
