Outside Air Temperature Sensor Test
WARNING: This page is about a different car, the 2009 Acura MDX, 2008 Acura MDX, and 2007 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.
- Remove the outside air temperature sensor (see OUTSIDE AIR TEMPERATURE SENSOR REPLACEMENT ).
- Dip the sensor in ice water, and measure the resistance. Then pour warm water on the sensor, and check for a change in resistance.
- Compare the resistance reading between the No. 1 and No. 2 terminals of the outside air temperature sensor with the specifications shown in the graph; the resistance should be within the specifications.
- If the resistance is not as specified, replace the outside air temperature sensor (see OUTSIDE AIR TEMPERATURE SENSOR REPLACEMENT ).
