The manifold absolute pressure sensor reads the amount of pressure or vacuum (also called “engine load”) in the intake manifold, where outside air is divvied up in proper amounts and ...

One such part is the manifold absolute pressure or MAP sensor. The MAP sensor is responsible for monitoring the air entering the engine through the intake manifold. That's important because ...

A bad oxygen sensor, mass air flow sensor, manifold pressure sensor, throttle position sensor, a stuck-open exhaust gas recirculation (EGR) valve or an engine vacuum leak can cause a lean running ...
