O2 sensors, task	Records the residual oxygen in the exhaust gas and sends a signal to the engine control unit. O ₂ -sensors upstream of the catalytic converter: The O₂ -sensor signal is needed for Lambda control Self adaptation of the mixture formation Function chain tests. O ₂ -sensors downstream of the catalytic converter: The O₂ -sensor signal is needed for Two-sensor control and EURO3/4 Monitoring catalytic converter efficiency
