German ROMELECTRA sensor ROMELECTRA model ROMELECTRA price

ROMELECTRA sensor is a sensor that measures the air flow drawn into the engine. In electronically controlled gasoline injection engines, to achieve the optimal mixture concentration under various operating conditions, it is essential to accurately measure the amount of air drawn into the engine at every instant, using this as the primary basis for the ECU to calculate (control) the fuel injection quantity. If the air flow sensor or its wiring fails, the ECU will not receive the correct intake air signal, preventing normal control of fuel injection, which will cause the mixture to be too rich or too lean, resulting in abnormal engine operation.
