Rear Wheel Speed Sensor

Why You Need This Part

This essential sensor measures your vehicle's rear wheel rotation speed. It sends real-time info to your car's anti-skid or ABS system, helping prevent wheel lock during hard braking. Safety systems rely on accurate input from this sensor to function effectively, especially on wet or slippery roads.

How It Works

Situated on the rear axle, it detects the speed of the wheel and transmits signals to your vehicle’s control unit. This data aids in regulating brake pressure, ensuring your tires retain grip under heavy or emergency braking situations.

Risks of a Faulty Sensor

• ABS warning light will illuminate.
• Traction and stability control functions may be disabled.
• Increased risk of skidding during sudden stops.
• Unusual braking response or noises.
