Standard Ignition ALS844 rear left ABS wheel speed sensor for the 1993-2001 Subaru Impreza and other vehicles reports wheel speed to the anti-lock brake system. If the old sensor or its wiring has failed, this one replaces it.
A lit ABS or traction control warning light can mean a wheel speed sensor has failed. Those signs alone do not prove this part is the problem, since a damaged wire elsewhere in the circuit is another common cause.
It fits the 1990-1999 Subaru Legacy as well. The 1993-2001 Subaru Impreza takes one sensor at this position; this listing is the rear left, and the rear right is ordered separately.
