Product Description:

 
Anti-lock Braking System Sensor

OE NO.:  30748149  32373146

Applicable vehicle type: For Volvo

The full name of the car ABS sensor is the Anti-lock Braking System Sensor, which is the core sensing component of the ABS system. It is installed on the bracket or hub of each vehicle wheel. By cooperating with a gear ring that rotates synchronously with the wheel, it real-time collects wheel speed signals and transmits them to the ABS electronic control unit (ECU). This enables anti-lock control during braking. Additionally, it can provide data support for systems such as the Vehicle Stability Control System (ESP), ensuring vehicle braking safety.

Fault Symptoms and Maintenance keys:

• Fault Warning Signals: The ABS fault light remaining on the dashboard is the most intuitive indication; vehicle drift or vibration during braking, or signs of tire lock-up during emergency braking may indicate sensor signal distortion; some vehicle models will trigger relevant fault codes due to sensor failure, which simultaneously affects the normal operation of associated systems such as ESP.
• Maintenance Specifications: Regularly check the gap between the sensor and the gear ring (typically requiring maintenance around 0.5mm), and clean impurities such as mud and iron filings in the gap; when replacing, prioritize original equipment manufacturer (OEM) parts or compliant brand parts for the adapted vehicle model to avoid signal mismatch; during installation, ensure secure fixation to prevent positional offset caused by vehicle vibration, which could affect measurement accuracy.
