Transmission Fluid Temperature Sensor "A" Circuit Low Input (P0712,P0713)
DESCRIPTION
The Automatic Transmission Fluid (ATF) temperature sensor converts the fluid
temperature into a resistance value for use by the TCM.
The TCM applies a voltage to the temperature sensor through terminal THO1 of
the TCM.
