Tech A says that reed switches produce air-conditioning voltage. Tech B says that a magnetic VSS can be troubleshot by checking to see if the sensor is producing a DC voltage when the output shaft is turning. Who is correct?
A) Tech A
B) Tech B
C) Both A and B
D) Neither A nor B

Question

Quizplus · Accepted Answer

Reed switches do not produce air-conditioning voltage; they are used for sensing and switching applications. A magnetic Vehicle Speed Sensor (VSS) typically produces an AC voltage, not DC, when the output shaft is turning.
