Note On Intermittents

If an intermittent Code B112 is being set, manipulate the related wiring while observing BCM data BD28. If the failure is induced, the reading will jump from its normal value to a reading outside the range of -34°F (-29°C) to 209°F (85°C).

If the value displayed by BD28 is not reasonably close to the corresponding gauge pressure reading, check for poor terminal contact or replace sensor.
