$139.90
The VEMO OE quality ABS speed sensor is engineered to the exact specifications of the vehicle manufacturer to ensure the replacement sensor is the same in quality and function as the part installed as original equipment.

The rotational speed of the wheels is transmitted from the sensor to the control unit and from there to the transmission, engine, navigation and chassis control systems. This data is essential for ABS, ASR and ESP, to prevent blocking or wheel spin. Due to their versatile use, the sensors make a direct contribution to driving dynamics and safety. Moreover, driving comfort can be improved, fuel consumption reduced and emission levels decreased. Failure of the wheel speed sensors means an acute safety risk! The cause may be electrical or mechanical disruption, for example increased wheel bearing play, a broken wire or a corroded plug contact. With more than 670 different wheel speed sensors for vehicles of all the leading manufacturers, the quality brand VEMO offers a high-quality alternative.

Product Features:
  • OE quality direct fit application
  • Manufactured to meet or exceed OE requirements and testing
  • Fuel consumption reduced and emission levels decreased
