• Robust Housing: Stainless steel construction protects against moisture, dust, and mechanical impact, extending service life.
• Low Power Consumption: Optimized for automotive power budgets, reducing strain on the vehicle’s electrical system.
• High Signal Fidelity: Maintains accurate wheel speed data even at high rotational speeds, critical for ABS and traction control performance.
• Easy Integration: Standard connector types and pinouts match OEM specifications, simplifying installation and diagnostics.

Installation Guidelines

1. Safety First: Disconnect the vehicle’s battery to prevent electrical shock or unintended system activation.
2. Remove Existing Sensor: Use a suitable socket set to detach the old sensor. Note any wiring harness connectors and their orientation.
3. Prepare the Mounting Surface: Clean the wheel hub area of debris, rust, or adhesive residue to ensure proper adhesion.
4. Position the New Sensor: Align the sensor’s magnetic pole with the wheel’s toothed ring. Secure it using the supplied mounting bracket and torque specifications.
5. Reconnect Wiring: Attach the harness connector, ensuring correct polarity and secure contact.
6. Test Functionality: Reconnect the battery and start the vehicle. Use an OBD‑II scanner to verify that wheel speed data is being transmitted correctly.

Troubleshooting Common Issues

Maintenance and Longevity Tips

• Regular Inspection: Periodically check the sensor’s mounting bolts for tightness, especially after heavy driving conditions.
• Clean Surroundings: Keep the area around the sensor free from oil, grease, and road salt to prevent corrosion.
• Avoid Physical Impact: The sensor is sensitive to shock; use protective covers if the vehicle operates in rough terrain.
