Electrical ASE prep Test

Two technicians are discussing an analog transmission range sensor on a late model vehicle. Technician A says that since these sensors use resistance to indicate gear selection, they can be tested with an ohmmeter. Technician B says to start the car and make sure the circuit is powered before using the meter. Who is correct?

• Technician A

• Technician B

• Both

• Neither
