Which of the following sensors can be used by the Powertrain Control Module (PCM) to judge engine load?
A) Manifold absolute pressure (MAP)
B) Accelerator Pedal Position Sensor (APPS)
C) Mass airflow (MAF)
D) Both A and C

Question

Quizplus · Accepted Answer

The PCM uses both the Manifold Absolute Pressure (MAP) sensor and the Mass Airflow (MAF) sensor to determine engine load. The MAP sensor measures the pressure inside the intake manifold, while the MAF sensor measures the amount of air entering the engine. Both provide critical data for calculating engine load.
