Keep your BMW's anti-lock braking system reading wheel speed accurately with the Standard Ignition ABS Wheel Speed Sensor ALS432. This front wheel speed sensor is a direct-fit replacement for the listed applications, including the 1992-1998 BMW 318I, 1991-1999 BMW 318IS, 1995-1999 BMW 318TI, 1987-1995 BMW 325IS, 1995-1999 BMW M3, and 1996-2002 BMW Z3 — see the Buyer's Guide tab for the full list.

  • Front position: mounts at the front wheel to monitor how fast that wheel is turning.
  • Signals the ABS control module: sends the wheel-speed reading the system uses for anti-lock braking and related functions.
  • Direct-fit replacement: installs on the listed BMW applications without modification.

An ABS wheel speed sensor measures the rotational speed of the wheel and reports it to the ABS control module. When a sensor stops sending a reliable signal, the system typically stores a fault and can disable anti-lock braking. If a failed front wheel speed sensor is the cause of an illuminated ABS warning light or a dropped wheel-speed signal, this ALS432 replaces it. Diagnose the cause before replacing.

Interchange: Manufacturer part number ALS432.
