Note On Intermittents
If an intermittent Code B111 is being set, manipulate the related wiring while observing BCM data BD27. If the failure is induced, the reading will jump from its normal value to a reading outside the range of -24°F (-33°C) to 409°F (209°C).
If the value displayed by BD27 is not reasonably close to the corresponding gauge pressure reading, check for poor terminal contact or replace sensor.
