Standard Ignition ABS Wheel Speed Sensor P/N:ALS417

Keep your anti-lock braking and traction-control systems reading wheel speed accurately with the Standard Ignition ABS Wheel Speed Sensor ALS417. It installs as a front wheel speed sensor for the 1999 Audi A6 [All] and 1999 Audi A6 Quattro [All], both of which use two of these sensors per vehicle.

• Front position: cataloged as a front ABS wheel speed sensor for the listed applications.
• Core function: monitors how fast the wheel is turning and sends that signal to the ABS/traction-control module.
• Direct-fit replacement: a direct-fit replacement for the listed 1999 Audi A6 and A6 Quattro applications.

The wheel speed sensor generates a signal the ABS control module uses to detect wheel lock-up and modulate braking. Signs this part may need replacing include an illuminated ABS or traction-control warning light, or ABS/traction-control features dropping out. Because those symptoms can have other causes, diagnose the fault before replacing. If a failed front wheel speed sensor is the cause, this replaces it. These applications use two sensors, so order two for a complete front-axle set.
