What is a four-sensor ABS?

Four-sensor ABS: One sensor is located at each wheel and monitored separately. This is the most common configuration with modern vehicles. The ABS wheel speed sensor can also be called an ABS brake sensor or, more plainly, an ABS sensor. Whatever it is called, it is a critical part of the ABS.

What is an ABS tachometer?

An ABS (Anti-lock Braking System) is an enhanced braking system which is commonly found in newer automobiles. An anti-lock brake sensor or ABS sensor is a type of tachometer that measures the rotational speed of a wheel and passes it to the car's Engine Control Module (ECM). The ABS sensor is also called the wheel speed sensor or ABS brake sensor.

Where is the ABS sensor located?

The ABS sensor is typically located in each wheel hub/rotor on a four channel ABS system. Some rear wheel drive applications have the sensor mounted in the rear differential. Will a malfunctioning ABS sensor illuminate the check engine light or affect vehicle operation?

How much does an ABS wheel speed sensor cost?

You can expect to pay about $100 to $150 for the wheel speed sensor and another $100 to $300 for the labor. ABS wheel speed sensors on luxury vehicles can often cost more, plus some models can be harder to work on, which increases the labor cost.
