Thermometer Test

THERMOMETER TEST
The thermometer function is supported by an Ambient Temperature Sensor, a wiring circuit, and a portion of the Overhead Console Trip Computer, Compass, and Thermometer Display Module display. The sensor is mounted outside the passenger compartment near the front and center of the vehicle.

If any portion of the Ambient Temperature Sensor circuit fails, the thermometer display will self-diagnose the circuit. An "SC"(short circuit) will appear in the display in place of the temperature, when the sensor is exposed to temperatures above 55 °C (131 °F), or if the sensor circuit is shorted. An "OC" (open circuit) will appear in the display in place of the temperature, when the sensor is exposed to temperatures below -40 °C (-40 °F), or if the sensor circuit is open.

The Ambient Temperature Sensor circuit can also be diagnosed using the following Sensor Test, and Sensor circuit Test. If the temperature sensor and circuit are confirmed to be OK, but the temperature display is inoperative or incorrect, see the Trip Computer, Compass, and Thermometer Display Module diagnosis.
