An oxygen sensor, also known as a lambda sensor, continually detects the oxygen content in the exhaust gases of an engine. The oxygen sensor output signal informs the vehicle's ECU (Electronic Control Unit) whether the AFR (Air-Fuel Ratio) is lean or rich. Based on this, the ECU adjusts the amount of fuel injected into the engine to achieve an optimal AFR.
