ABS Sensors

ABS is an assistance system that helps the driver to drive more calmly by eliminating the effect of wheel locking during hard braking. It is part of a suite of vehicle electronic systems that use wheel speed sensors to determine wheel speed and act accordingly. The ABS sensor is one of your vehicle's sensors. It is part of the ABS that prevents your wheels from locking during hard braking. There is one ABS sensor for each wheel. The sensor then sends the information to the ECU, which releases the wheel.

They are usually located near the wheels, near the hubs. Each wheel has its own ABS sensor.

Step 1: Remove the wheel

Step 2: Remove the arch liner clip

Step 3: Disconnect the ABS sensor

Step 4: Remove the mounting rubbers

Step 5: Unbolt the ABS sensor from the wheel knuckle

Step 6: Install the new ABS sensor and secure it.

Step 7: Reconnect the ABS sensor wiring connector

Step 8: Install the wheel

Step 1 Preparation: Ensure the vehicle is turned off and the ABS disengages.

Step 2 Disconnect: Disconnect the electrical connector of the ABS sensor.

Step 3 Set the multimeter: Set the multimeter to the ohmmeter function.

Step 4 Measure resistance: Connect the multimeter probes to the pins on the ABS sensor connector. Make sure the probes make good contact with the connector pins. The ABS sensor should have two pins.

Step 5 Resistance Reading: Read the resistance value displayed on the multimeter.  If the resistance reading is outside this range, it may indicate a sensor malfunction.

Step 1 Raise the vehicle: Jack up the vehicle so you have a few inches under the wheel and place it on jack stands.

Step 2 Locate the sensor: Locate the ABS sensors.

Step 3 Remove the sensor: Use a suitable wrench to unscrew the bolts and carefully remove the sensor. Use lubricant if necessary.

Step 4 Clean ABS sensor: Gently wipe the sensor surface with a clean cloth, preferably microfiber.

Step 5 Brake cleaner or degreaser: If the sensor is very dirty or greasy, you can spray or gently apply the cleaner to a clean cloth and gently rub the sensor surface.

Step 6 Reinstall: Carefully reinstall the sensor, making sure it's properly positioned and securely fastened.

Step 7 Once the cleaning is complete, start the engine and see if the ABS warning light goes out.

Step 8 Test Drive: Perform a test drive at low speed to verify that the ABS warning light remains off and that the braking system is operating properly.
