Honda NXR160/BROS ESDD Oxygen Sensor 36531-KRE-K01 Direct Fit

When your Honda NXR160 or BROS ESDD shows idle instability, weak acceleration, abnormal fuel consumption, or the engine check light (codes like P0134, P0135) on the dashboard, this indicates the oxygen sensor may be aged or failed, unable to accurately monitor oxygen content in the exhaust. The sensor normally detects oxygen concentrations before and after the catalytic converter and feeds the signal back to the ECU to precisely control the air-fuel ratio, ensuring efficient combustion and emissions compliance. OEM number 36531-KRE-K01 (corresponding to 36531KREK01) precisely matches Honda NXR160/BROS ESDD models; direct replacement in the original position. Ensure sensor threads are clean and tighten to recommended torque with a dedicated tool (about 45-55 N·m); avoid over-tightening and prevent wiring touching high-temperature exhaust areas.
