Automotive glossary: What is an Oxygen Sensor or Lambda Probe? (Abbr.: OXS)

Definition of Oxygen Sensor: In order to obtain an optimum efficiency and life span of the exhaust gas catalytic converter, it is necessary to permanently control the gasoline air composition accordingly. In order to gauge the rest oxygen assay in the waste gas, there are one or more lambda probes installed in the exhaust gas system. These relay their measurement result as an electric signal to the engine control, so that via adaption of the fuel injection amount or the air intake quantity, an optimum exhaust gas composition for the catalytic converter function is achieved.
