P0712 Transaxle Fluid Temperature Sensor Circuit Low Circuit

Auto Repair and Component Location Study Guide and General Description The automatic transmission 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 transmission 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. Study Guide and DTC Detecting Condition Item Study Guide and Detecting Condition Auto Repair and Possible Cause DTC Strategy ● Check for Voltage range ● Sensor signal circuit is short to ground. ● Faulty PCM Enable Conditions ● Always Threshold Value ● Voltage < 0.05V Diagnostic Time ● More than 1 sec Fail Safe ● Learning control and Intelligent shift are inhibited. ● Fluid temperature is regarded as 80°C Study Guide and Specification TEMP.(°C) RESISTANCE(kΩ) TEMP.(°C) RESISTANCE(kΩ) -40(-40°F) 139.5 80(176°F) 1.08 -20(-4°F) 47.7 100(212°F) 0.63 0(32°F) 18.6 120(248°F) 0.38 20(68°F) 8.1 140(284°F) 0.25 40(104°F) 3.8 160(320°F) 0.16 60(140°F) 1.98  Auto Repair , Study Guide , Auto Repair , Study Guide , Auto Repair more trouble and Study Guide
