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 ...

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 ...

While this sounds simple enough, the MAF also has to contend with changes in outside air temperature, air pressure ... in the intake tube. Unplug the electrical connector from the sensor, then ...
