Fig. 008 - Chart C-1D Map and Baro Output Check
NOTE: MAP and BARO sensors are essentially the same device--one--MAP--measures the difference between pressure in the manifold and
atmospheric pressure, and the other--BARO--measures atmospheric pressure.
1. Check that sensor voltage is highest when manifold pressure is highest--output normally is in the middle range for specific altitudes.

Low voltage increases spark advance.
