In addition to providing voltage to the computer's internal circuits, what is the purpose of the reference voltage regulator within a modern PCM?
A) To provide 5 volts to the sensors on the input side of the PCM
B) To provide 5 volts to the actuators on the output side of the PCM
C) To provide 12 volts to the sensors on the input side of the PCM
D) To provide 12 volts to the actuators on the output side of the PCM

Question

Quizplus · Accepted Answer

The reference voltage regulator within a modern PCM (Powertrain Control Module) primarily provides a stable 5 volts to the sensors on the input side. This reference voltage is crucial for the sensors to function correctly and provide accurate readings to the PCM.
