What are the symptoms of a faulty Audi mass airflow sensor?
1 Answers
Audi mass airflow sensor failure symptoms and the function of the mass airflow sensor are as follows: Audi mass airflow sensor failure symptoms: Inaccurate mass airflow signal, interrupted mass airflow signal, excessive fuel injection, poor fuel pump operation; difficulty starting the engine, unstable idle speed; drop in mass airflow signal voltage, leading to reduced fuel supply, no mass airflow signal output; unstable engine operation, decreased power, poor acceleration. Function of the mass airflow sensor: The mass airflow sensor, also known as the mass airflow meter, detects the amount of air entering the engine and converts this information into an electrical signal through circuit connections, which is then input to the ECU for determining fuel injection quantity and ignition timing.
