

Go to "SIGNAL CIRCUIT INSPECTION" procedure.  

NO  



Check for Short in harness. Repair as necessary and Go to "VERIFICATION OF VEHICLE 
REPAIR" procedure.  

SIGNAL CIRCUIT INSPECTION 

1. Ignition "OFF".  

2. Disconnect "TRANSAXLE RANGE SWITCH" and "TCM (PCM)" connector.  

3. Measure resistance between each terminals of the sensor harness to check for Short.

DTC P0712 FLUID (OIL) TEMPERATURE SENSOR CIRCUIT - LOW

COMPONENT LOCATION

GENERAL DESCRIPTION 

The automatic TRANSAXLE fluid (ATF) temperature sensor is installed in the Valve Body. This sensor uses a 
thermistor whose resistance changes according to the temperature changes. The TCM supplies a 5V reference 
voltage to the sensor, and the output voltage of the sensor changes when the ATF temperature varies. The 
automatic TRANSAXLE fluid (ATF) temperature provides very important data for the TCM's control of the 
Torque Converter Clutch, and is also used for many other purposes. 

DTC DESCRIPTION 

This DTC code is set when the ATF temperature output voltage is lower than a value generated by thermistor 
resistance, in a normal operating range, for approximately 1 second or longer. The TCM regards the ATF 
temperature as fixed at a value of 80°C (176°F).
