Note On Intermittents

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

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