本田氧传感器36531-PGM-003空燃比监测精准耐用

Honda oxygen sensor 36531-PGM-003, directly replaces OEM 36531PGM003; ready to use after installation; stable compatibility. Core function is to monitor air–fuel ratio and feed ECU to precisely control injection, improving combustion efficiency. Fits most Honda models including Civic, Accord, CR-V; refer to compatibility list for years. Replacing resolves excessive fuel consumption, engine sluggishness, and high emissions; if idle rough, acceleration hesitation, or check engine light on, sensor aging is likely.
