The ambient temperature sensor is an encapsulated
thermistor that provides the ECU with an input of
external air temperature. Ambient sensor is a ther-
mistor that decreases its resistance when
temperature increases and increases when tempera-
ture decreases.
LOCATION
Outside Ambient Temperature (OAT) sensor located
on cross member behind the front bumper.
