Mixed-Air Temperature Sensor
WARNING: This page is about a different car, the 2001 Saab 9-3 and 2000 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.
Mixed-air temperature sensor is supplied with 5.0 volts through a 10,000 ohm resistor in ACC control module from 39-pin connector terminal No. 19 (Violet wire). Mixed-air temperature sensor ground is supplied from ACC control module 39-pin connector terminal No. 38 (Blue/Red wire on 2000 models; Red/Blue wire on 2001 models). As temperature decreases sensor resistance increases. See MIXED-AIR TEMPERATURE SENSOR RESISTANCE table.
