SIE-Sensorik switch A switch that measures the air flow drawn into the engine. For electronically controlled gasoline injection engines, in order to obtain the optimal mixture concentration under various operating conditions, it is necessary to accurately measure the amount of air drawn into the engine at every instant, using this as the main basis for the ECU calculation (control) of fuel injection quantity. If the air flow switch or wiring fails, the ECU will not receive the correct intake air signal, preventing normal control of fuel injection quantity, which will cause the mixture to be too rich or too lean, resulting in abnormal engine operation.
