Honda Civic Front Oxygen Sensor 36531-RNA-A01 Air-Fuel Ratio Precise Monitoring

Honda Civic 1.8L (2006-2011) and some CR-V models use front oxygen sensor with OEM number 36531-RNA-A01 (compatible with 234-9126 and other replacements). Uses engine-level zirconia ceramic element and high-temperature alloy housing; materials and welding methods are consistent with OEM; measured response speed and signal stability meet OEM standards. Installation should avoid thread damage; monitors exhaust oxygen content in real time and provides feedback to ECU to adjust air-fuel ratio, ensuring combustion efficiency and emissions compliance.
