Standard Ignition ABS Wheel Speed Sensor P/N:ALS440

Keep your ABS and traction-control system reading wheel rotation accurately with the Standard Ignition ABS Wheel Speed Sensor ALS440. This is a rear-position wheel speed sensor that installs as a direct-fit replacement for the 1996-1999 BMW 318TI and the 1997-2002 BMW Z3, restoring the signal the ABS control module needs to monitor how fast the wheel is turning.

• Rear wheel speed sensor: monitors rotational speed at the rear and reports it to the ABS/traction-control module.
• Direct-fit replacement: a straightforward swap for the failed original on the listed BMW applications.
• Signal accuracy: designed to deliver a clean speed reading so the electronic control unit can manage anti-lock braking and traction control.

A wheel speed sensor is a common wear item, and signs it may need replacing include an illuminated ABS or traction-control warning light, or ABS/traction control that behaves erratically. Because those symptoms can also come from wiring, a damaged tone ring, or the control module, diagnose the cause before replacing. If the sensor is confirmed faulty, ALS440 replaces it.
