Intake Air Temperature Sensor
Remove intake air temperature sensor from dynamic chamber. See Figure or Figure . Using a heat lamp, ohmmeter and thermometer, measure and record resistance of sensor at various temperatures. Refer to the INTAKE AIR TEMPERATURE SENSOR RESISTANCE specification table. Replace sensor if not within specification.
