前氧传感器 36531-PPA 适配多款本田/通用车型 原厂编码

Front oxygen sensor (OEM number 36531-PPA) directly replaces the factory part and is compatible with 36531-PPA-G03 and many Honda and General Motors vehicles. It monitors exhaust oxygen content and feeds signals to the ECU to precisely control the air-fuel ratio, ensuring combustion efficiency. After installation, it can resolve high fuel consumption, weak acceleration, or constant engine warning lights, especially for high-mileage vehicles. Idle is unstable, exhaust emits black smoke, or annual inspection shows excessive emissions; aging front oxygen sensor is likely—replace to save fuel and protect the catalytic converter.
