The lambda sensor is the main sensor in catalytic exhaust gas purification. It measures the residual oxygen content in the exhaust gas so that the ratio of fuel and intake combustion air can be optimally adjusted.

Lambda sensors constantly detect chemical parameters in the exhaust gas and convert them into electronic signals. This information is transmitted to the engine control unit, which adjusts the mixture formation in the combustion chamber according to the evaluated results. As a result, the emission of pollutants such as nitrogen oxides, hydrocarbons, and soot is significantly reduced.
