BMW Serie 5 - Video tutorial

Model: BMW Serie 5 E39 - Years 1995-2003
Part: Engine
Operation: Check the operating parameters of the air mass meter

The air mass meter provides the engine management control unit with information relating to the volume of air drawn in according to the position of the accelerator and according to which the control unit itself must adjust the volume of fuel to be injected to ensure correct power delivery; it is clear that incorrect information from this sensor will manage the fuel injection with inaccurate values at the expense of performance and consumption; if you want to check the correct functioning of the mass air sensor, you must be familiar with the use of the multimeter since you will have to measure the resistance values and the voltage output from the sensor according to the position of the throttle, feeding the sensor itself with a 9 volt battery.
