Frequently Asked Questions

What does the ALS549 do?

It is an ABS wheel speed sensor that monitors the rotational speed of a wheel and sends that signal to the ABS control module, which uses it to modulate braking and help prevent wheel lockup.

What are signs this sensor may need replacing?

Common signs include an illuminated ABS warning light and ABS-related trouble codes. Diagnose the cause first, since these symptoms can have other sources such as wiring or the control module.

Which vehicles does it fit?

It is a direct-fit replacement for listed 1991-1997 GM applications, including the Chevrolet S10 and Blazer, GMC Jimmy, Sonoma, Syclone and Typhoon, and Oldsmobile Bravada. See the Buyer's Guide tab for the full list.

How many sensors do I need?

The listed applications use one per vehicle, and this listing is for a single sensor.

Will replacing this turn off my ABS light?

If a failed wheel speed sensor is the cause, replacing it with the ALS549 addresses that. Have the system scanned first to confirm the sensor, not the wiring or module, is at fault.
