2002 GMC Envoy Ambient Temp Sensor

GMC Envoy On the 2002 GMC Envoy, when the outside temp display is not working, this is most commonly due to a problem with the Ambient Air Temp sensor. The air temperature sensors are a 2 wire negative temperature co-efficient thermistor. As the air temperature surrounding the sensor increases, the sensor resistance decreases. The sensor signal voltage decreases as the resistance decreases. The sensor operates within a temperature range between -40°C (-40°F) to 101°C (215°F) . You can find the sensor under the hood mounted to the radiator fan shroud….
