Keep your anti-lock braking, traction, and stability systems reading wheel rotation accurately with the Standard Ignition ABS Wheel Speed Sensor ALS471. It installs as a direct-fit replacement for the listed applications: the 2003-2006 Porsche Cayenne [All], 2008-2010 Porsche Cayenne [All], 2016 Audi TT [All], and 2018 Audi Q2 Quattro [All].
An ABS wheel speed sensor measures how fast a wheel is turning and sends that signal to the ABS/traction control module, which uses it to modulate braking and manage wheel slip. When a sensor fails or its signal drops out, the system can no longer trust that wheel's reading.
- Direct-fit replacement: fits the listed applications.
- Restores the wheel-speed signal: supplies the module with an accurate rotational-speed reading.
- Supports ABS/traction functions: the signal this sensor provides feeds anti-lock braking and traction/stability control.
Signs this sensor may need replacing include an illuminated ABS or traction control warning light and related stored fault codes. Diagnose the cause before replacing, as wiring, the tone/reluctor ring, or the module can produce similar signs. If a faulty wheel speed sensor is the cause, this replaces it.
Interchange: Manufacturer part number ALS471.
