HVAC 90 F. OUTSIDE AIR TEMPERATURE SENSOR FUNCTION: 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: The sensor is located on the lower hood latch brack- et on the top radiator tie member. CONNECTOR DETAILS PINOUT DETAILS PIN NO DESCRIPTION 1 Sensor Analog supply 2 Gnd REMOVAL 1. Open the bonnet. 2. Carefully pull out the ambient temperature sen- sor from its mounting bracket. 3. Disconnect the electrical connection. 4. Take out the sensor. INSPECTION: Measure the resistance between the sensor termi- nals under at least two temperatures. The resistance values should meet the values shown.
