Temperature Display

The driver information display applies voltage to the ambient air temperature sensor. The ambient air temperature sensor is a thermistor (the temperature and the resistance vary inversely):
^ As the resistance of the ambient air temperature sensor increases, the driver information display senses a larger voltage drop across the ambient air temperature sensor, indicating a lower temperature.
^ As the resistance of the ambient air temperature sensor decrease, the driver information display senses a smaller voltage drop across the ambient air temperature sensor, indicating a higher temperature.

If the temperature is below 3°C (38°F) the temperature digits will toggle between displaying the following items for 2 minutes:
^ The outside temperature
^ The word ICE

This condition will occur once per ignition cycle.

The driver information display uses the vehicle speed signal from the Powertrain Control Module (PCM) in order to determine when to update the temperature display with a new outside air temperature reading. The vehicle must be driven over 16 km/h (10 mph) before the temperature display will be updated.
