Front Right Wheel Speed Sensor (ABS)

This front-right wheel speed pickup is a key input for the ABS and stability systems. It constantly reads how fast the wheel is turning and sends a clean signal to the control unit. That data helps the truck brake straight, keep traction on wet roads, and prevent wheel lock during hard stops ⚙️.

Why this part is needed

Modern Toyota braking relies on accurate wheel speed feedback. When one wheel starts to slow faster than the others, the system knows it’s about to lock and reacts instantly.

How it works

The sensor “counts” the teeth or magnetic pattern on the tone ring/hub as it rotates. It creates an electrical pulse that matches wheel speed, allowing ABS, traction control, and stability control to modulate brake pressure precisely.

What happens if it fails

A broken or dirty sensor may trigger ABS/traction warning lights, cause erratic ABS activation, disable stability control, and increase stopping distance on slippery surfaces. You may also notice a dead speed-related signal for one corner and stored fault codes ⚠️.
