Replacing Engine Mass Airflow Sensor

Model: BMW Serie 5 E39 - Years 1995-2003
Part: Air filter

Lift the hood and turn on the ignition of your vehicle. Use a multimeter to test the connectors of the mass airflow sensor. Next, remove the clamps securing the inlet and outlet hoses of the sensor. After disconnecting the connectors, compare the old sensor with the new one. Once you confirm they are the same part, install the new sensor in the same orientation as the old one, which is also indicated on the part itself. Finally, reconnect all the connectors.
