Abstract
The present invention is one in which an off board Mass Air Flow (MAF) sensor is used to diagnose the internal combustion engine. The MAF sensor is connected to the air induction system of the engine. The sensor is then powered from the vehicles battery. The MAF sensor is designed for lower air flow rates produced from the engine such as; crank, idle, and light load. The sensor creates an output voltage that is proportional to the volumetric air flow of each cylinder entering the engine. This MAF voltage output signal is then used to diagnose engine pumping issues.
