Keep your anti-lock braking system reading wheel speed accurately with the Standard Ignition ABS Wheel Speed Sensor ALS636, a direct-fit replacement for the rear-left position on the 2005-2023 and 2025 Nissan Frontier. It monitors how fast the wheel is turning and sends that signal to the ABS control module, which the system uses to manage anti-lock braking and related stability functions.

What it does:

  • Rear-left wheel speed sensing: cataloged for the rear-left position on the listed Frontier applications.
  • Signal to the ABS module: reports wheel rotation speed so the module can modulate braking during an ABS event.
  • Direct-fit replacement: designed to install in place of the original sensor on the listed applications.

A failing wheel speed sensor can trigger the ABS or traction-control warning light or cause the system to drop out. If a faulty rear-left sensor is the cause on your Frontier, this replaces it — diagnose the fault before replacing, as wiring, tone rings, and the module can produce similar signs.

Interchange: Manufacturer part number ALS636.

Frequently Asked Questions

Which vehicles does the ALS636 fit?

What position is this sensor for?

The catalog lists it for the rear-left wheel position on the applicable Nissan Frontier applications.

What does an ABS wheel speed sensor do?

It measures how fast the wheel is turning and sends that signal to the ABS control module, which uses the data to manage anti-lock braking and related functions.

What are signs this sensor may need replacing?

An illuminated ABS or traction-control light, or the system dropping out, can be signs. Diagnose the cause first, since wiring, the tone ring, or the module can produce similar symptoms.

Does it fit a 2024 Frontier?

The listed applications are 2005-2023 and 2025 Nissan Frontier. The 2024 year is not among the listed applications, so verify fitment for your vehicle.
