Note On Intermittents
WARNING: This page is about a different car, the 1990 Cadillac Seville and 1990 Cadillac Eldorado. However, it is still accessible from the selected car via links, so may be relevant.
If intermittent Code B113 is being set, manipulate related wiring while observing BCM parameter BD25. If failure is induced, reading will jump from its normal value to a reading outside range of -34°C to 96°C. If value displayed by BD25 is not reasonably close to actual temperature of air at sensor, check for poor terminal connections or replace sensor.
