Keep your anti-lock brake and traction control systems reading wheel rotation accurately with the Standard Ignition ABS Wheel Speed Sensor ALS1149. It installs as a direct-fit replacement in the rear left position on the 2002-2007 Mitsubishi Lancer, generating a wheel-speed signal and passing it to the ABS control module so the system can manage wheel lockup and slip.

  • Position: cataloged for the rear left wheel location on the listed application.
  • Function: senses rear-left wheel rotation and reports it to the ABS and traction control module.
  • Direct-fit: a direct-fit replacement for the listed Mitsubishi Lancer application.
  • Signs it may need replacing: an illuminated ABS or traction control warning light, or a stored wheel-speed fault code for that wheel — if the rear-left sensor is the cause, this replaces it.

ABS wheel speed sensors can fail from wiring damage, contamination, or an air gap issue, so diagnose the cause before replacing. Confirm fitment for your vehicle before ordering.

Why is my ABS light on — will this fix it?

An ABS or traction light can come from several causes, including wiring or another sensor. If the rear-left wheel speed sensor is the cause, replacing it with the ALS1149 addresses it; diagnose first.
