Honda Accord Front Oxygen Sensor 36531-P0A Replaceable with 36531-PGM

Honda Accord: if engine warning light, noticeably higher fuel consumption, acceleration weakness, or idle instability appear, this often indicates aging of the upstream oxygen sensor, which cannot accurately monitor exhaust oxygen content. In normal operation, this sensor feeds ECU fuel mixture data to help maintain optimal combustion efficiency, reducing emissions and boosting power. OEM number 36531-P0A; interchangeable with 36531-PGM; fits numerous Honda Accord models (e.g., 2003-2007 2.4L/3.0L). Ensure sensor threads are clean and apply anti-seize; operate with cold engine to avoid burns.
