Symptoms of Fiat error code P0351

The P0351 trouble code can be revealed by various symptoms. The most common is the lack of control of the ignition coil. This causes the engine to run irregularly or not on all cylinders.

The cause of the problem

This malfunction is usually caused by a defect in the Magneti Marelli IAW 59F / 59M / 5AF / 5AM ECU. In the Fiat Punto, for example, the ECU is mounted on the engine: a position that is of course not ideal in terms of heat and vibrations. This increases the chance of defects in the part.
