HONDA CIVIC 2017-2021 Oxygen Sensor 36531-5AF-H01

HONDA CIVIC 2017-2021 Oxygen Sensor 36531-5AF-H01 are used in the feedback control system of electronic fuel injection devices to detect the oxygen concentration and air-fuel ratio in the exhaust, monitor theoretical air-fuel combustion in the engine, and transmit feedback signals to the computer. The working principle of an oxygen sensor is similar to that of a battery, and the zirconia element in the sensor acts like an electrolyte.
