本田雅阁氧传感器 36531-RAC 适配211200-2330

When your Honda Accord has idle instability, noticeably higher fuel consumption, or the Check Engine light on, it usually indicates oxygen sensor aging or failure, unable to accurately monitor oxygen content in exhaust. This sensor, when functioning, provides real-time feedback of air-fuel ratio to the ECU to help maintain optimal combustion efficiency, reducing emissions and improving power response. OEM number 36531-RAC; fits 211200-2330 and various Honda Accord models. Install when cold to avoid burns; use a dedicated socket for tightening to prevent thread damage or seal leaks.
