There is a sensor on the air intake called the mass air flow sensor. This sensor calculates how much air to mix with the fuel.You can bypass the MAF sensor, and allow the O2 sensor to calculate how much air is needed.

  • What happens if the mass airflow sensor is bad?

  • That is because if the sensor is bad or giving a wrong reading, then the cars guess might be closer to the actual amount of air that the engine is getting giving you a more accurate fuel mixture. Why disconnect the mass airflow sensor? So, why might you want to disconnect the mass airflow sensor and drive around like that?

  • Why does my car die when I Disconnect the mass airflow?

  • If the car dies when you disconnect the mass airflow sensor, then that means it was working right and that your computer has issues. It isn鈥檛 able to use the tables programmed in it to guess the amount of fuel needed.
