Explanation:
this answer is taken directly from the book
One method of determining engine load is through the use of a manifold absolute pressure (MAP) sensor. The MAP sensor can be either directly bolted to the intake manifold or connected through a vacuum hose.
Most modern MAP sensors use a type of flexible silicon chip within a sealed chamber; the chip changes resistance when manifold pressure flexes the chip.
