German PROSE MESSTECHNIK sensor PROSE MESSTECHNIK model PROSE MESSTECHNIK price

PROSE MESSTECHNIK sensor is a sensor that measures the air flow into the engine. In electronically controlled 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 fuel injection, which will cause the mixture to be too rich or too lean, causing the engine to
