To ensure the reduction of harmful emissions produced by the internal combustion engine, the lambda or oxygen sensor has become an important piece of technology. Optimal combustion is required in order to ensure an ideal conversion rate of the catalytic converter. The lambda sensor principle is based on an oxygen comparison measurement. This means that the remaining oxygen content of the exhaust emission is compared with the oxygen content of the ambient air.
