Wheel Speed Sensor Resistance

Plug the wheel speed sensor bore in order to prevent debris from falling into the hub during service. 1112009 If the reading is less than 350 ACmVs remove the wheel speed sensor.

928 Tech Tips

But if that series resistor were mounted in the module to 5 volts and where it exits the module with a tap on it for the signal only two wires would be needed for the actual sensor.

Wheel speed sensor resistance. Use a Volt-Ohm meter to measure resistance across the connector pins. Just had the car on a reader and didnt have any ABS codes but daughter took it back to school yesterday and this morning she tells me the ABS light came on. Confirm that chocks are in place on the vehicle.

OK - between 1200 and 2700 ohms. Symptoms of ABS sensor related faults. The sensor produces a square wave signal with a high signal of 193 volts and a low signal of 064 volts.

If the resistance or voltage output. So you can say that it works like a tachometer. 572016 If mounted in the sensor three wires are required ground voltage 5V typical and the junction between the Hall Effect and series resistor for the signal output.

Today we will learn about how to test wheel speed sensor when you think it malfunctions so that the smooth driving doesnt stop. To 220C the sensor resistance can vary from 1100 to 3400 ohms. Wheel speed sensor circuits and connectors are also prone to the atmosphere and possible electrical failures such as open or short circuits or high circuit resistances.

Symptoms of ABS sensor related faults. If not OK replace the sensor. To avoid possible connector seal damage it is recommended to first check sensor resistance or AC voltage output at the ECU connections.

The typical reading for a passive wheel speed sensor is between 1000 and 2500 ohms. Active wheel speed sensors are susceptible to damage from incorrect testing methods. In particular the application of resistance testing.

Wheel speed sensor circuits and connectors are also prone to the atmosphere and possible electrical failures such as open or short circuits or high circuit resistances. 1112010 Anyone know the the resistance specs for the wheel speed sensors on a 93. Ive got the electronics manual for the car but it doesnt have the specs on the sensors.

The specification for active sensors is between 1000 and 2500 ohms. Raise the wheel off the ground to test the suspect wheel speed sensor. Take note of the readings on the multimeters screen With the probes contact to the pins ask the assistance to turn the wheel hub as fast as he can.

The sensor reads the total number of wheel rotation and informs the driver about the same. 100 and 4500 Ohms and the sensor resistance that is measured is within 10 Ohms with the meter If the sensor is damaged replace the damaged probes in either position. 1082019 A wheel speed sensor as the name senses the speed of a wheel.

10112012 for a passive wheel speed sensor is between 1000 and 2500 ohms. The typical reading for a passive wheel speed sensor is between 1000 and 2500 ohms. The high signal must cross 129V and the low signal must cross 097V to low.

862015 The wheel speed sensors normally function from 12 to 24 VDC power supply where the reverse polarity protection is standard and the sensor has built in protection against pulsed transients to -60V -40V. Release the parking brakes. A magneto resistive wheel speed sensor power input can range from 12V-5V from the ABS controller.

10112012 The sensor andor harness should be disconnected from the circuit so you are not measuring resistance in the ABS unit. If the sensor circuit has too much resistance reads open or is shorted little or no resistance measure the resistance across the sensor itself. 4202013 The sensor andor harness should be disconnected from the circuit so you are not measuring resistance in the ABS unit.

Some vehicles even compare the wheel speed sensor readings against the vehicle speed sensor VSS to make sure all of these sensors are accurate and working correctlyAdvertisementClick Here to Read. 292020 Having confirmed that you can now go ahead and test wheel speed sensor resistance by attaching the red and the black probes to the pins of the speed sensor. A good wheel speed sensor and circuit will typically have a resistance of 800 to 1400 ohms specs vary so refer to a manual for the exact numbers.

Clean the wheel speed sensor mounting surface using a wire. Refer to the applicable Wheel Speed Sensor Replacement procedure in the ABS sub-section of the Service Manual. 1012008 With magnetic WSS sensors you can check the integrity of the sensor by connecting an ohmmeter across its terminals.

The resistance specs will vary depending on the application but most sensors should read 450 to 2200 ohms always look up the exact specifications because they can vary a great deal from one vehicle application to another. Not OK - less than 1200 or more than 2700 ohms. Wheel speed sensors WSS provide essential wheel speed information not only for anti-lock brake systems ABS but also for traction control and stability control systems.

This is a normal range for all passive sensors.
