Note On Intermittents

If intermittent Code B111 is being set, manipulate related wiring while observing BCM parameter BD27. If failure is induced, reading will jump from its normal value to a reading outside range of -34°C to 209°C. If value of sensor displayed by BD27 is not reasonably close to pressure gauge reading, check poor terminal connections or replace sensor.
