Standard Ignition ABS Wheel Speed Sensor P/N:ALS3051
Standard Motor Products
Standard Ignition ALS924 rear left ABS wheel speed sensor for the 1985-1991 Mazda RX-7 senses wheel speed for the anti-lock brake system. This Standard Ignition ABS wheel speed sensor is engineered specifically for Mazda vehicles.
A lit ABS warning light, or an ABS that stops working, can come from a failing wheel speed sensor. A damaged harness, a damaged tone ring or a faulty ABS control module can be behind the same signs, so find the cause before buying. This listing is one sensor for the rear left wheel; the rear right is a separate part.
It is a direct-fit replacement for the 1985-1991 Mazda RX-7 at the rear left wheel.
