Transmission Fluid Temperature Sensor "B" Circuit Low Input (P2742,P2743)
DESCRIPTION The No. 2 ATF temperature sensor is installed in the transmission valve body assembly. If the ECM detects an abnormally high ATF temperature near this sensor, it illuminates the warning indicator. HINT: The temperature of ATF easily rises when towing, climbing hills, in ...

Transmission Fluid Temperature Sensor "A" Circuit Short To Ground (P071011)
DESCRIPTION The No. 1 ATF temperature sensor converts the fluid temperature into a resistance value for use by the ECM. The ECM applies a voltage to the temperature sensor through terminal THO1 of the ECM. The sensor resistance changes with the ATF temperature. As the temperature becomes hi ...
