Note On Intermittents
If Code B111 is set with Code B112, check for an intermittent open in circuit No. 736 between splice "S1" and "S2". If an intermittent Code B111 is being set, check Code B111 snap data value for high side temperature, BD27 display. If BD27 display value is less than -33°C, code was caused by an open in circuit No. 732, circuit No. 736 or high side temperature sensor. If BD27 display is greater than 209°C, code resulted from a short to ground on circuit No. 732 or a shorted high side temperature sensor. Manipulate related wiring while observing BD27 display. If failure is induced, reading will jump from its normal value to a reading outside the range of -24°F (-33°C) to 409°F (209°C).
If value displayed by BD27 display is not reasonably close to corresponding gauge pressure reading, check for poor terminal contact or replace sensor.
