Standard Ignition ABS Wheel Speed Sensor P/N:ALS3168
Standard Motor Products
Standard Ignition ALS2509 rear right ABS wheel speed sensor for the 2011-2016 Subaru Impreza and other vehicles senses wheel speed and sends it to the ABS. It is an OE replacement made for Subaru vehicles.
A lit ABS warning light can mean this sensor is worn or failing, though a damaged tone ring or a chafed wire can be behind it too.
This sensor fits the 2011-2016 Subaru Impreza and the 2013-2016 and 2018 Subaru XV, and it was tested on vehicles for proper fit. This listing is one sensor for the rear right wheel, and the rear left sensor on that axle is a separate part. The rear right of the 2011-2016 Subaru Impreza takes one sensor.
