Rear Right Wheel Speed Sensor for Toyota

This rear-right speed pickup is a key input for the ABS, traction control, and stability systems. It tells the ECU how fast the wheel is turning in real time, helping the car brake straight, keep grip, and avoid wheel lock on slippery roads 🚙⚙️.

Why this part is needed

Modern Toyota brake and safety modules must “see” each wheel speed separately. The rear-right signal is used to balance brake pressure, improve stopping distance, and support hill/road control functions.

How it works

The sensor reads a rotating tone ring/encoder on the hub or axle. As the wheel turns, it generates an electrical pulse signal. The ABS module compares all four wheels and reacts instantly when one slows too fast during braking.

What happens if it’s broken

Common results are ABS light on, traction/stability warnings, no ABS operation, longer stops on wet roads, and occasional ABS pump noise or incorrect activation. In some cases the speedometer/assist features may act odd, especially under load 🛠️.
