The cause of the problem

Although the error code description directs you directly to an error in the engine computer, other parts in the Fiat can also cause this malfunction. This malfunction can also be caused by a defective fuse, a broken cable, a weak battery or a defective injector. If the specialist's diagnosis shows that these components are good, then this P0606 malfunction is probably caused by a defect in the Magneti Marelli IAW 5NF ECU. This ECU is mounted on the engine. The vibrations and heat that the ECU has to process make it extra sensitive to malfunctions.
