Oxygen sensor 1, also known as the upstream sensor, is located before the catalytic converter and measures the oxygen levels in the exhaust gases to help the engine control module (ECM) adjust the air-fuel mixture for optimal combustion. Oxygen sensor 2, or the downstream sensor, is positioned after the catalytic converter and monitors its efficiency by comparing the oxygen levels in the exhaust before and after the converter, ensuring that it is effectively reducing emissions.
