This module introduces the student to the fundamentals of EV sensors and actuators. In addition to pressure and temperature sensors, the operating principles of ultrasonic sensors and the purpose of digital cameras in driver assist systems is also covered. The student will also learn the main types of actuators on the body of EVs and be able to describe the operation of solenoid valves and motor position sensors. In addition, the steps required for troubleshooting sensors and actuators is also discussed.
