Question

Technician A says a typical Manifold Absolute Pressure (MAP) sensor can be connected directly to the intake manifold or connected through a vacuum hose. Technician B says most modern MAP sensors do not use a flexible silicon chip within a chamber anymore. Who is correct

Answer 1

the correct answer is: technician A

Step-by-step 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.
