German CARPRESSE sensor CARPRESSE model CARPRESSE price

CARPRESSE sensor is a sensor that measures the air flow rate drawn into the engine. For electronic control gasoline injection engines, 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 to calculate (control) the fuel injection quantity. If the air flow sensor or wiring fails, the ECU will not receive the correct intake air signal, preventing normal control of the fuel injection quantity, which will cause the mixture to be too rich or too lean, resulting in abnormal engine operation.
