路虎揽胜氧传感器LR062826 0258030155 FPLA-9G444-BA，精确空燃比控制

Land Rover oxygen sensor replacement options (LR062826 / 0258030155 / FPLA-9G444-BA) for L322, L405 and other models with 3.0L or 5.0L engines. Wide-range sensor accurately measures lambda value, informs ECU of lean or rich mixture to optimize fuel economy. Check exhaust pipe threads for corrosion before installation; use thread-tapping if needed. If MIL flashes, power response is slow, or emissions exceed limits during inspection, replace to restore proper air-fuel control.
