Product Overview

Standard Ignition ALS3330 is built for vehicles that rely on accurate wheel speed input to support ABS operation. The sensor mounts at the wheel and uses a bolt-on design with a rectangular dual-connector layout and a 41.75-inch harness, making it a direct replacement style part for the specified Mazda 6 rear right location. If your Mazda 6 shows ABS-related warning lights or wheel speed signal faults, this sensor addresses the rear right wheel input path used by the braking system.

Common Issues This Sensor Can Address

• ABS warning light triggered by a rear wheel speed signal fault
• Loss of wheel speed data from the rear right sensor location
• Brake system fault codes related to wheel speed monitoring
• Traction control or stability system warnings tied to ABS input
• Intermittent braking system communication caused by a damaged sensor or harness

Installation Notes

Verify connector style, harness routing, and bolt-hole alignment before installation. Inspect the wheel-end tone ring, wiring path, and connector terminals for corrosion, debris, or physical damage before replacing the sensor. On 2018-2021 Mazda 6 rear right applications, confirm the sensor seats fully at the wheel mounting point and that the harness is routed away from moving suspension components.
