Note On Intermittents

If intermittent Code B112 is being set, manipulate related wiring while observing BCM parameter BD28. If failure is induced, reading will jump from its normal value to a reading outside range of -34°C to 87°C. If value displayed by data parameter BD28 is not reasonably close to corresponding pressure gauge reading, check for poor terminal connections or replace sensor.
