ABS wheel speed sensor 30773743 ABS sensor for Volv o Rear axle wheel speed sensor​

Product Description:

 
ABS sensor
OE NO.: 30773743

Applicable vehicle type: For VO LVO

The automotive ABS sensor (Anti-lock Braking System Sensor), also known as the wheel speed sensor, serves as the core sensing component of the vehicle's anti-lock braking system (ABS). It is responsible for continuously capturing wheel speed signals and transmitting them to the ABS electronic control unit (ECU). This provides precise data support for the system to determine wheel lock-up conditions and adjust braking pressure, making it a critical component for ensuring stable braking performance and driving safety.

Key Routine Maintenance Points

• Regular Cleaning: Clean the sensor head and gear ring surfaces of iron filings and silt every 20,000 kilometres or six months (particularly after driving on muddy or dusty roads).
• Wiring Harness Inspection: Every 10,000 kilometres, inspect the wiring harness for damage or ageing, and check connectors for looseness or oxidation. Replace any faulty components promptly.
• Toothed Ring Maintenance: Inspect the toothed ring for wear on the teeth profile. Should any teeth be missing or the ring be deformed, replace both the toothed ring and sensor simultaneously.
• Avoid Modification Impact: When replacing wheels or tyres, ensure the toothed ring remains in its original mounting position to prevent misalignment between the sensor and toothed ring.
