Vemo V38-72-0063 Speed Sensor

The Vemo V38-72-0063 is a high‑performance speed sensor designed for Nissan vehicles, including the Almera, Tiida, Sentra, Altima, and various hatchback models. It delivers precise wheel speed data to the vehicle’s engine control unit (ECU), enabling optimal fuel injection timing, ignition control, and transmission shifting.

Key Functionalities

• Accurate Wheel Speed Measurement: Utilizes a magnetic pickup coil that generates a square‑wave signal proportional to wheel rotation speed.
• High Signal Integrity: Features low noise and high immunity to electromagnetic interference, ensuring reliable operation in harsh automotive environments.
• Compact Design: Small form factor allows easy installation without requiring additional space or modifications.
• Durable Construction: Made from corrosion‑resistant materials that withstand temperature extremes and road debris.

Compatibility Overview

The sensor is engineered to fit a wide range of Nissan models, including but not limited to:

• Nissan Almera (II) Hatchback – 2000‑2002
• Nissan Tiida – 2001‑2006
• Nissan Sentra (Sunny) – 1999‑2004
• Nissan Altima – 1998‑2003
• Various LatiO and Hatchback variants with 1.8L or 2.0–2.4L engines.

Each model’s wheel hub and sensor mounting interface are matched to the Vemo V38-72-0063, ensuring a secure fit and optimal signal output.

Installation Guide

1. Remove the Old Sensor: Disconnect the battery, locate the wheel hub assembly, and unscrew the existing speed sensor using a socket set. Carefully detach the electrical connector.
2. Prepare the New Sensor: Verify that the Vemo V38-72-0063 matches the vehicle’s specifications. If necessary, clean the mounting surface to remove rust or debris.
3. Mount the Sensor: Align the sensor with the wheel hub’s magnetic pickup slot. Secure it using the supplied bolts and torque specifications.
4. Reconnect Wiring: Attach the electrical connector, ensuring a snug fit. Reconnect the battery.
5. Test Functionality: Start the engine and observe the ECU diagnostics or OBD‑II reader for correct wheel speed readings. Verify that there are no error codes related to the speed sensor.

Performance Benefits
