ABS Speed Sensor – WHT 003 858 (Service Tech)

Description

The ABS Speed Sensor WHT003858 by Service Tech is an OE-style wheel speed sensor designed as a direct replacement for select Volkswagen and Audi models. Mounted at the wheel hub, it continuously monitors individual wheel rotation and delivers a precise signal to the ABS/ESP control unit. As a result, safety systems such as anti-lock braking, traction control, and electronic stability control operate correctly under all driving conditions.

Over time, original sensors degrade due to internal electrical faults, moisture intrusion, or physical damage to the wiring and connector. Consequently, you may experience ABS/ESP warning lights, disabled traction control, or intermittent cruise-control operation. Replacing the worn unit with this Service Tech ABS Speed Sensor WHT003858 restores accurate wheel-speed feedback and normal braking and stability system performance — at a cost-effective price.
