Rear ABS Sensor Rotor for Nissan

This rear anti-skid rotor is a key part of the ABS/traction control system . It provides a precise speed signal reference for the wheel sensor, helping the control unit detect wheel slip and keep braking stable on wet, gravel, or emergency stops.

Why this part is needed

Every time the wheel turns, the rotor’s toothed/magnetic pattern creates a readable pulse for the ABS sensor. The system uses that pulse to prevent wheel lock and to support safer steering control during braking.

How it works

The rotor spins with the rear hub/axle. As its pattern passes the sensor tip, the sensor generates a changing signal. The ABS module compares wheel speeds and rapidly adjusts brake pressure when it sees a skid starting.

What happens if it’s broken

If cracked, rust-swollen, bent, or missing teeth, the signal becomes weak or erratic. You may get ABS/SLIP warning lights, pulsation at low speed, longer stopping distance, or ABS that cuts in incorrectly. In some cases, traction control may be disabled until fixed ⚠️.
