Description And Operation

There are four temperature sensors on the Heating, Ventilation, and Air Conditioning (HVAC) housing output. Two are on the lower part and the others are on the upper part.

These sensors are Negative Temperature Coefficient (NTC) type. This means that their resistance decreases when temperature increases.

The sensor resistance is about 10 kilohms at 25°C (77°F) and 32, 650 kilohms at 0°C (32°F).

The air duct temperature sensors are diagnosed using a scan tool. Refer to DIAGNOSIS AND TESTING .

The air duct temperature sensors cannot be adjusted or repaired and must be replaced if inoperative or damaged.
