Product Introduction 1000020170 ABS Sensor is the wheel speed detection component of HFCN721 light truck anti-lock braking system. It captures real-time wheel rotational speed signals and transmits data to ABS ECU, enabling the controller to adjust brake pressure to prevent wheel lockup during emergency braking or slippery road conditions. This aftermarket replacement sensor fixes ABS warning light on dashboard, loss of anti-lock function and inaccurate speed reading caused by broken internal wire, damaged magnetic induction head and corroded connector pins of original sensors, improving vehicle braking stability and avoiding skidding risks for urban logistics light cargo vehicles.

Product Advantages High-sensitivity induction head delivers stable and precise wheel speed signal under vibration and temperature variation. Reinforced outer cable has excellent wear resistance and waterproof performance to resist mud and moisture. OEM matching plug ensures seamless connection with vehicle wiring harness. Each sensor undergoes signal output testing before shipment, reliable detection performance and reduces hidden safety hazards during rainy or slippery road braking.

Applicable Models Designed for JAC HFCN721 light truck series, matches original wheel ABS assembly for short-distance delivery and urban logistics cargo vehicles.

FAQ

Q1: What warning appears when ABS sensor fails?
A1: ABS warning lamp lights up on instrument panel, anti-lock function is disabled during hard braking.
Q2: What can damage the ABS sensor signal head?
A2: Stone impact, mud buildup and excessive clearance between sensor and signal ring will weaken signal.
Q3: Should I check the tone ring while replacing ABS sensor?
A3: Yes, inspect the tone gear for cracks, rust and missing teeth which will also affect signal reading.
Q4: Can the truck still drive if ABS sensor is broken?
A4: Basic hydraulic brake still works, but anti-lock protection fails, drive cautiously especially on wet slippery roads.
