Standard Ignition ABS Wheel Speed Sensor P/N:ALS802
Standard Ignition ALS636 rear left ABS wheel speed sensor for the 2005-2023 Nissan Frontier reports wheel speed to the ABS module. It is engineered specifically for Nissan vehicles.
A failing sensor can show up as a lit ABS or traction control warning light. A damaged tone ring, a worn wheel bearing or harness damage can be behind these signs too, so find the cause before buying. This listing is one sensor for the rear left wheel, and the rear right takes its own. The 2005-2023 Nissan Frontier takes one on this side.
This sensor fits the 2005-2023 Nissan Frontier and the 2025 Frontier.
