Fiat P0352 fault code: the faults, the symptoms and the fix

Fiat P0352 fault code: What does it mean?

The troublesome P0352 fault code can present in multiple Fiat models and relates to the 1.2-litre 8-valve petrol engine, that has been in use since the late 1990s. The fault is described as “Ignition coil B primary/secondary, interruption/short circuit of cylinder 2”

This engine can be found in many models, including but not limited to:

    What symptoms does the P0352 fault code cause?

    Once the fault code is stored in the engine ECU, in most cases the engine management light will be illuminated. The driver could also notice rough running, or an irregular idle, potentially even an engine that is not running on all four cylinders. This could be caused by a missing coil control signal.

    What to do if your Fiat has a P0352 fault code stored?

    Unfortunately, if you’re experiencing some of the symptoms mentioned above and your car has the P0352 fault code stored, there is a high possibility that your ECU has failed. Typically, we see this failure occurring with he Magneti Marelli IAW 59F.

    Each ECU has two ignition drivers, with each driver controlling a coil that provides the ignition for 2-cylinders (DIS ignition). In some cases, this error code is found alongside the P0351 fault code. The mounted directly to the engine, for example in the Fiat Punto, in these cases the additional heat and vibrations can cause faults, whereas in the Seicento the unit is mounted on the chassis leg.
