Test H - Map/BP Sensor
WARNING: This page is about a different car, the 1987 Mercury Topaz and 1987 Ford Tempo. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Barometric pressure sensor output is digital and must be measured with MAP/BP tester.
To prevent replacement of good components, be aware that the following non-EEC related areas may be at fault: unusually high/low atmospheric barometer reading, kinked or blocked vacuum lines, engine condition (valves, vacuum leaks, valve timing, EGR valve, etc.).
