Air Mass System Test For Diesel Engines: Notes

The air mass system consists of several component groups that ensure the optimum fresh air supply to the engine at every operating point. Malfunctions in these component groups cause a variety of disturbances in driving operation, for example lack of power, black smoke, etc.

The air mass system test runs an overall check of the air mass system and thus allows clear pinpointing of the cause of the fault to the defective component group(s).
