Note On Intermittents
If ambient temperature drops to less than about -31°F (-35°C), this code should be ignored. If B110 is set with any of the following codes: B119, B120, B122, B132 or B440, the most likely cause is an intermittent open in circuit No. 736.
If an intermittent Code B110 is being set, check B110 snap data value for outside temperature BD26. If BD26 value is less than -29°F (-34°C), code was caused by an open circuit No. 735 or 736, or outside temperature sensor. If BD26 value is greater than 135°F (57°C), code was caused by a short to ground on circuit No. 735 or a shorted outside temperature sensor. Manipulate related wiring while observing BCM display BD26. If failure is induced, reading will jump from its normal value to a reading outside the range of -31°F (-35°C) to 137°F (58°C).
If value indicated by BD26 display is not reasonably close to actual temperature of air at sensor, check for poor terminal contact or replace sensor.
