Installation Guide

1. Preparation: Disconnect the vehicle’s battery to prevent electrical hazards. Verify that the vehicle is on a flat surface and secured with jack stands.
2. Remove Old Sensor: Locate the front wheel speed sensor housing. Unscrew the mounting bolts, gently detach the sensor from the axle shaft, and note the orientation for reinstallation.
3. Clean Mounting Surface: Use a clean rag to remove any debris or old gasket material from the mounting area.
4. Install New Sensor: Place the Vemo V38-72-0026 into the housing, aligning it with the axle shaft. Secure with bolts and apply the rubber gasket to ensure vibration isolation.
5. Reconnect Wiring: Attach the sensor’s electrical connector to the vehicle’s harness, ensuring a snug fit. Verify polarity if applicable.
6. Test Functionality: Reconnect the battery, start the engine, and observe the ABS/ESP modules for proper wheel speed readings. Use diagnostic tools to confirm signal integrity.

Maintenance & Troubleshooting

While the Vemo sensor is designed for long‑term reliability, routine checks can preempt failures:

• Visual Inspection: Periodically inspect the connector and wiring for corrosion or damage.
• Signal Verification: Use a scan tool to monitor wheel speed pulses; irregularities may indicate sensor wear.
• Cleaning: Gently clean the sensor housing with non‑abrasive wipes if dirt accumulates.

If the vehicle’s ABS warning light illuminates or traction control fails, consider the following diagnostic steps:

1. Check for blown fuses related to wheel speed input.
2. Inspect the sensor connector for loose pins or corrosion.
3. Verify that the sensor is correctly aligned with the axle shaft; misalignment can cause signal loss.
4. If issues persist, replace the sensor with a new Vemo V38-72-0026 unit.
