Why does the ABS light come on on a new wheel?

What’s happening is that the ABS computer is seeing a different in signal strength between the new and old wheel speed sensors. It determines that the weaker signal is indicating a wheel lockup, so it falsely activates the ABS on that wheel. Or, it determines that the weak signal indicates a bad sensor, so it lights up the ABS light.

How do you fix an ABS warning light?

How does a wheel speed sensor work in a car?

Wheel speed sensors are installed in your car to determine how fast each wheel is turning. They are responsible for sending data to the anti-lock brake system (ABS) module. The module uses that information to regulate ABS operation and (on most newer vehicles) traction control and stability control.

Why is my abs light on and Trac off?

Here’s why: Older ABS braking systems used a steel toothed ring and a magnetized wheel speed sensor. As rust accumulated on the tone ring it would throw debris onto the magnetic sensor and that debris would interfere with the signal, causing the ABS to activate prematurely. GM changed the wheel speed sensor and tone rings in these vehicles.

What causes ABS light?

An ABS light can be caused by a faulty wheel speed sensor, wheel speed sensor circuits, the ABS motor/pump or the ABS module itself. Most of the time the light is on because of a faulty wheel speed sensor.

What sensors make the ABS work?

Basically, the ABS speed sensor consists of a magnetic sensor which carries out the principal function. Upon the principle of induction, when the tone ring slots pass from within the magnetic lines of forces of the magnetic sensor present in the ABS sensor, a voltage will be induced. This voltage then generates a signal for the ABS control system.
