Standard Ignition ABS Wheel Speed Sensor P/N:ALS3230
Keep your anti-lock braking system reading wheel rotation accurately with the Standard Ignition ABS Wheel Speed Sensor ALS830. This front-left sensor installs as a direct-fit replacement for the 1993-1999 Subaru Impreza and 1990-1997 Subaru Legacy, restoring the signal your ABS control module relies on.
An ABS wheel speed sensor measures how fast the wheel is turning and reports that data to the ABS control module. When the original sensor fails, the module can lose or misread that input, which is why a faulty unit is a common reason for an illuminated ABS warning light.
Interchange: Manufacturer part number ALS830.
