Note On Intermittents

If an intermittent Code B112 is being set, manipulate related wiring while observing BD28 display. If failure is induced, reading will jump from its normal value to a reading outside the range of -34°F (-29°C) to 201°F (94°C).

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