Transmission Fluid Temperature Sensor "A" Circuit Short to Battery or Open (P071015)
DESCRIPTION The ATF temperature sensor converts the automatic transaxle fluid (ATF) temperature into a resistance value for use by the ECM.
The ECM applies voltage to the temperature sensor through terminal THO1 of the ECM.
The sensor resistance changes with the ATF temperature. As the temperatu
