Transmission Fluid Temperature Sensor "A" Circuit Range/Performance (P071000)
DESCRIPTION The ATF temperature sensor converts the automatic transaxle fluid (ATF) 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 tempera
