ABS 30755 Wheel Speed Sensor

ABS 30755 Wheel Speed Sensor

The ABS 30755 Wheel Speed Sensor is a critical component in modern vehicle safety systems, providing precise wheel rotation data to the Anti‑Lock Braking System (ABS) and Electronic Stability Control (ESC). Designed for high reliability and durability, this sensor ensures that braking performance remains optimal under all driving conditions.

Key Functionalities

• High Accuracy Wheel Speed Detection: The sensor converts the rotational speed of each wheel into an electrical signal with minimal error margin, enabling the ABS controller to modulate brake pressure accurately.
• Passive Magnetic Design: Utilizing a passive magnetic sensor architecture eliminates the need for external power sources, reducing complexity and enhancing fault tolerance.
• Wide Operating Temperature Range: Engineered to function reliably from -40 °C to +120 °C, it withstands extreme climates without performance degradation.
• Low Power Consumption: The sensor’s low current draw conserves vehicle battery life and reduces heat generation within the brake assembly.

Compatibility and Application Scope

The ABS 30755 is specifically calibrated for a range of Mitsubishi models, including but not limited to the Space Star and Carisma series. Its design accommodates both front‑wheel and rear‑wheel installations, with variants available for left‑hand drive (LHD) and right‑hand drive (RHD) configurations.

Installation Guidelines

1. Preparation: Disconnect the vehicle’s battery to prevent accidental electrical discharge. Remove any protective covers or brackets that may obstruct sensor access.
2. Removal of Old Sensor: Carefully detach the existing wheel speed sensor by loosening its mounting screws and gently pulling it away from the wheel hub, taking care not to damage the wiring harness.
3. Mounting the ABS 30755: Align the new sensor with the hub’s magnetic field. Secure it using the supplied mounting hardware, ensuring a snug fit that maintains proper alignment for accurate signal transmission.
4. Wiring Connection: Connect the sensor’s wiring harness to the vehicle’s diagnostic port or dedicated ABS connector, following the manufacturer’s pinout diagram. Verify all connections are tight and insulated.
5. Testing: Reconnect the battery and start the engine. Use a scan tool to confirm that wheel speed data is being transmitted correctly and that no fault codes appear related to the sensor.

Maintenance Tips

• Inspect the sensor’s wiring for signs of wear, corrosion, or fraying during routine brake system checks.
• Clean the sensor housing with a soft brush and mild solvent to remove debris that could interfere with magnetic coupling.
• Avoid using high‑pressure water jets directly on the sensor, as this can dislodge internal components.

Troubleshooting Common Issues
