Outside Air Temperature Sensor Testing
WARNING: This page is about a different car, the 1998 Acura 3.5RL. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
To avoid damage to sensor, use an ohmmeter with a measuring current of one milliamp or less.
Unplug connector from outside air temperature sensor, located behind center of front bumper. Measure resistance across sensor terminals. See OUTSIDE AIR TEMPERATURE SENSOR RESISTANCE table. If resistance is not as specified, replace sensor.
