Note On Intermittents:

If an intermittent Code B113 is being set, manipulate the related wiring while observing BCM data BD25. If the failure is induced, the reading will jump from its normal value to a reading outside the range of -34° to 209°F.

If the value displayed by BD25 is not reasonably close to the actual temperature of the air at the sensor, check for poor terminal contact or replace sensor.
