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.
A Code B110 will be stored in memory whenever the ambient temperature drops to less than -29°F (-34°C). This code should be ignored if this cause is suspected. If intermittent Code B110 is being set, manipulate related wiring while observing BCM parameter BD26. If failure is induced, reading will jump from its normal value to a reading outside range of -34°C to 87°C. If value displayed by BD26 is not reasonably close to actual temperature of air at sensor, check for poor terminal connections or replace sensor.
