B OAT (Outside Ambient Temperature)
The ambient temperature sensor is an encapsulated thermistor that provides the ECU with an input of
external air temperature. Ambient sensor is a thermistor that decreases its resistance when temperature
increases and increases when temperature decreases.
Location
Outside Ambient Temperature (OAT) sensor located under the front grill / front bumper.
Inspection:
Measure the resistance between terminals of the sensor at minimum two temperatures. The resistance value
should match with stated values of resistance in table below
