Where is the mass airflow sensor located?

Hello, this vehicle does not have a Mass Air Flow sensor, this is a speed density engine and uses a MAP sensor (Manifold Absolute Pressure sensor) to calculate engine load, as well as engine speed, throttle position, intake air temperature and coolant temperature. Most engines use one or the other, so a MAP sensor or a MAF sensor. There are a few that use both, but it is rare. Are you getting a check engine light and a specific code?
