ABS 30464 Wheel Speed Sensor

Overview of the ABS 30464 Wheel Speed Sensor

The ABS 30464 Wheel Speed Sensor is a critical component in modern vehicle safety systems, specifically designed to monitor wheel rotation speed and provide real-time data to the Anti‑Lock Braking System (ABS). By accurately measuring each wheel’s velocity, this sensor enables the ABS controller to modulate brake pressure, preventing wheel lockup during emergency braking and maintaining steering control.

Key Functionalities

• High Precision Speed Detection: Utilizes a magnetic or Hall‑effect principle to generate pulses proportional to wheel rotation speed.
• Robust Signal Output: Delivers a clean, low‑noise digital signal to the ABS module, ensuring reliable operation even under harsh driving conditions.
• Wide Temperature Range: Operates effectively from -40 °C to +120 °C, accommodating extreme climates and engine bay heat.
• Long‑Term Durability: Constructed with corrosion‑resistant housings and high‑grade materials to withstand vibration, moisture, and road debris.

Design & Construction

The sensor’s architecture is engineered for optimal performance in automotive environments. Key design elements include:

• Compact Housing: Fits seamlessly into the wheel hub assembly without compromising space or weight distribution.
• Sealed Electronics: Protects internal circuitry from dust, water, and oil ingress, meeting IP67 standards.
• Integrated Magnet or Hall Element: Depending on the variant, it may use a permanent magnet for inductive sensing or a Hall‑effect transistor for magnetic field detection.
• Standardized Connector: Features a 3‑pin or 4‑pin plug compatible with most ABS control units, simplifying installation and maintenance.

Compatibility & Vehicle Integration

The ABS 30464 Wheel Speed Sensor is specifically engineered for rear wheel applications on a range of Nissan models. Commonly matched vehicles include:

• Nissan Primera (5‑door, Traveller WP11)
• Nissan Maxima / Maxima QX IV A32 2.0 (103 kW, model year 2019)
• Nissan Cefiro II Stufenheck
• Other Nissan platforms requiring a rear‑right wheel speed sensor with the 30464 designation.

When selecting this sensor, verify that the vehicle’s ABS module and wiring harness are compatible. The sensor’s pinout and signal characteristics align with standard Nissan ABS architecture, ensuring seamless integration.

Installation Guidelines

1. Safety First: Disconnect the battery to prevent accidental electrical discharge during installation.
2. Remove Existing Sensor: Detach the wheel hub assembly and carefully unscrew the old sensor, noting its orientation and mounting position.
3. Prepare the New Sensor: Inspect for damage, clean the mounting surface, and apply a thin layer of anti‑seize compound if recommended by the manufacturer.
4. Mounting: Secure the ABS 30464 sensor in place using the supplied screws or bolts. Ensure torque specifications are met to avoid loosening over time.
5. Wiring Connection: Connect the sensor’s plug to the vehicle’s harness, matching pins accurately. Verify polarity and continuity with a multimeter.
6. Reassembly: Reinstall the wheel hub assembly, tighten all fasteners, and reinstall the wheel.
7. System Check: Reconnect the battery, start the engine, and use an OBD‑II scanner to confirm that the ABS module registers the new sensor’s signals without fault codes.
