Note On INTERMITTENTS
If ambient temperature drops to less than about -36°F (-38°C), this code should be ignored. If Code B110 is set with Code B119, B120, B122, B132 or B440, an intermittent open in circuit No. 736 is most likely cause.
If an intermittent Code B110 is being set, check Code B110 snap data value for outside temperature (BD26). If BD26 value is less than -35°F (-37°C), code was caused by an open in circuit No. 735 or 736 or outside temperature sensor. If BD26 value is greater than 129°F (54°C), code was caused by a short to ground on circuit No. 735 or a shorted outside temperature sensor. Manipulate related wiring while observing BD26 display. If failure is induced, reading will jump from its normal value to a reading outside range of -36°F to 131°F (-38°C to 55°C).
If BD26 display value is not reasonably close to actual temperature of air at sensor, check for poor terminal contact or replace sensor.
