Wheel Speed Sensor (WSS) Quiz

What is the typical voltage output range of a passive Wheel Speed Sensor (WSS) when tested with an AC voltage meter?

• 0.5 to 1 volt

• 1 to 2 volts

• 2 to 3 volts

• 3 to 4 volts

What is the normal resistance range for passive sensors as specified in the article?

• 100 to 500 ohms

• 500 to 1,000 ohms

• 1,000 to 2,500 ohms

• 2,500 to 5,000 ohms

According to the article, what should be done when testing a passive WSS to ensure accurate readings?

• Connect the positive lead to the signal wire and the negative to the ground

• Disconnect the sensor from the circuit

• Test only at high speeds

• Use a digital multimeter set to resistance mode

How can a Wheel Speed Sensor (WSS) be identified as passive or active based on the article?

• By the color of the sensor wires

• By the location of the sensor on the vehicle

• By the type of voltage it outputs when tested

• By the resistance measurement

What is the typical voltage range directly from the ABS module in a passive Wheel Speed Sensor (WSS) system?

• 0.5 to 1.0 volts

• 1.5 to 5 volts

• 1.5 to 3 volts

• 1.5 to 2.5 volts

What can cause unwanted ABS activations in passive WSS?

• Corrosion and misalignment of the tone ring

• Overheating of the sensor

• Low battery voltage

• Faulty wiring in the dashboard

How do active Wheel Speed Sensors (WSS) differ from passive ones in terms of signal output?

• Active WSS output an analog signal

• Active WSS output a DC square wave signal

• Active WSS output a sine wave signal

• There is no difference in signal output

What is a recommended method to detect the magnetic teeth on the tone wheel of an active WSS?

• Using a multimeter

• Passing a ferrous metal component by the rings

• Applying thermal imaging

• Visual inspection only

Where is the sensor tip of an active WSS typically located?

• Inside the vehicle's dashboard

• Mounted next to a tone ring inside a hub or knuckle

• On the outer surface of the tire

• Attached to the vehicle's transmission

What is the voltage of the power supply wire to the active wheel speed sensor when the vehicle is off?

• 11.30 volts

• 12.07 volts

• 13.69 volts

• 0.30 volts
