ABS sensor A-Premium Front ABS Wheel Speed Sensor for Volvo ABS Speed Sensor 30748149

Product Description:

ABS Speed Sensor

OE numbers: 30748149

Applicable vehicle type: For Volvo

The automotive ABS wheel speed sensor is the 'eye' of the Anti-lock Braking System (ABS) and electronic stability program (ESP), traction control system (TCS), and other chassis electronic control systems. It is responsible for real-time monitoring of the rotational speed of each wheel, converting the rotational speed signals into electrical pulses and sending them to the ECU. These pulses are used to calculate slip rate and determine if the wheels are about to lock up, thereby enabling precise regulation of braking pressure.

Installation and Maintenance Key Points:

• Gap Check: Use a plastic feeler gauge, standard 0.5-1.2 mm; deviation will report 'signal loss'.
• Gear Ring/Magnet Ring Cleaning: Accumulation of iron filings and brake dust will reduce amplitude, leading to false triggering.
• Wiring Route: Keep away from high-voltage ignition wires and motor phase wires to avoid EMI overlap.
• Waterproofing of Connectors: Ensure the sealing ring is intact and there is no water ingress and crystallization after exposure to water.
