Genuine 47900-4BF0A ABS Wheel Speed Sensor - Rear

The Genuine 47900-4BF0A is an OEM ABS wheel speed sensor designed for rear wheel position applications. This factory-spec sensor plays a critical role in your vehicle's anti-lock braking system by continuously monitoring and transmitting wheel speed data to the ABS control module.

Key Features:

• Genuine OEM quality sensor manufactured to Nissan factory specifications
• Rear position sensor (fits left rear or right rear)
• 2-pin electrical connector design
• Direct replacement for original equipment
• Sold individually (vehicles typically require 2 rear sensors)

Function:

The ABS wheel speed sensor calculates wheel rotation speed and transmits this data to your vehicle's anti-lock braking system computer. This information allows the ABS system to modulate brake pressure and prevent wheel lockup during hard braking, maintaining vehicle stability and steering control. A failed wheel speed sensor will typically trigger the ABS warning light and may disable anti-lock functionality.
