An oxygen sensor (or lambda sensor, where lambda refers to air–fuel equivalence ratio, usually denoted by λ) or probe or sond, is an electronic device that measures the proportion of oxygen (O 2) in the gas or liquid being analyzed.
An oxygen sensor is an electronic device that measures the proportion of oxygen in the exhaust gasses exiting an engine. Located in the exhaust system, it provides real-time data to the vehicle’s Engine Control Unit (ECU), which uses this information to adjust the air-fuel mixture for optimal combustion.
How does an O2 sensor work? Most cars have at least two oxygen sensors located throughout the exhaust system; at least one in front of the catalytic converter and one or more downstream from the catalytic converter. The “pre-cat sensor” regulates fuel supply, while the downstream sensor measures the efficiency of the catalytic converter.
