ABS 30316 Wheel Speed Sensor

ABS 30316 Wheel Speed Sensor

The ABS 30316 Wheel Speed Sensor is a high‑performance component designed to monitor the rotational speed of each wheel in modern vehicles equipped with an Anti‑Lock Braking System (ABS). By providing precise data to the vehicle’s electronic control unit, it ensures optimal braking performance and enhances overall safety.

Core Functionality

This sensor operates on the principle of a Hall Effect transducer. As the wheel turns, a magnetic field generated by a permanent magnet passes through the Hall element, producing an electrical signal proportional to the wheel’s rotational speed. The sensor then sends this signal to the ABS module, which processes it in real time.

For precise fitment, consult the vehicle’s service manual or a certified technician.

Installation Guide

1. Safety First: Disconnect the battery and lift the vehicle using jack stands.
2. Remove Old Sensor: Detach the wheel, then unscrew the existing sensor from the hub or ABS module bracket. Note the orientation of the magnetic pole.
3. Prepare New Sensor: Align the Hall element with the magnet’s field; ensure no debris interferes with contact points.
4. Mount Sensor: Secure the sensor using the supplied mounting hardware, tightening to manufacturer torque specifications.
5. Reconnect Wiring: Plug the 4‑pin connector into the vehicle’s harness. Verify polarity and continuity.
6. Test Functionality: Reconnect the battery, start the engine, and observe the ABS module diagnostics for proper sensor operation.

Performance Highlights

• High Accuracy: Delivers precise wheel speed data even at high RPMs.
• Robust Construction: Resistant to vibration, moisture, and temperature extremes.
• Low Power Consumption: Optimized for efficient ABS operation.
• Long‑Term Reliability: Designed to maintain performance over thousands of miles.

Maintenance Tips

Regular inspection is recommended, especially after events that could damage the sensor (e.g., pothole impact). Clean the sensor housing with a soft brush and check for corrosion on connectors. Replace immediately if any irregularities are detected.
