✔What does an ABS Sensor do?

The anti-lock braking system uses an ABS or wheel speed sensor to monitor the speed of the wheel, which then sends this information to the ABS computer. In the event of an emergency stop, the ABS computer will use this information to prevent the brakes from locking. If the wheel speeds are not equal, the computer will regulate the anti-lock feature until the speeds are the same

✔Where are ABS sensors located?

The ABS sensor is usually located in each wheel hub or rotor on a four channel ABS system. The ABS sensor may also be mounted in the rear differential in some rear wheel drive vehicles.

✔What are the indications of a malfunctioning ABS sensor?

An ABS sensor and wiring can be visually inspected for exposed wires or broken connections. The sensor may also be tested for OE-specified resistance with an ohmmeterh then sends this information to the ABS computer. In the event of an emergency stop, the ABS computer will use this information to prevent the brakes from locking. If the wheel speeds are not equal, the computer will regulate the anti-lock feature until the speeds are the same

✔ABS Fault light is on

One of the most common indications of a faulty ABS sensor would include the lighting up of the ABS light or the traction control light in the dashboard of the vehicle. If both your ABS Light and brake system light come on, this is an emergency and you need to stop driving right away and check your entire brake system.
