Detailed Description

Standard Ignition ALS2509 is engineered as a direct OE-style replacement ABS wheel speed sensor for the rear right side on select Subaru models. It uses a rectangular single-connector layout, bolt-mount installation, and a spindle mounting location to match the original sensor configuration. The 1120 mm harness length provides the needed routing for the vehicle-side connection, while the 2-terminal blade design supports proper electrical interface.

Use this Subaru ABS wheel speed sensor when servicing the rear right wheel speed signal on 2011-2016 Impreza, 2013-2016 XV, 2014-2016 Forester, and 2018 Forester and XV applications. Standard Ignition ALS2509 is a practical replacement for restoring ABS sensor input on these vehicles.

Common Issues This Part Addresses

• ABS warning light caused by a failed rear wheel speed sensor
• Intermittent wheel speed signal loss at the rear right wheel
• Fault codes related to ABS sensor circuit performance
• Erratic ABS operation from damaged sensor wiring or connector wear
• Loss of accurate wheel speed data to the brake control system

Installation Notes and Tips

Install at the rear right spindle location and verify connector shape, terminal style, and harness routing before final assembly. Inspect the mounting point and surrounding wiring for corrosion, abrasion, or debris that could affect sensor performance. Confirm vehicle application by year, make, model, and position before installation.

Quality Assurance

Standard Ignition ALS2509 is an OE replacement part built to match the original sensor form and connection style for the listed Subaru applications. It is designed for direct replacement use on the specified rear right fitments.
