    How does P1303 differ from P0303?

    Just depends how the scan tool and protocol interprets the fault..they are the same fault.

    Hey did you get anywhere with the P1303 code on your vehicle, the same code just came up on my 19 488. Any input would be appreciated.

    Mine ended up being a fouled spark plug likely from old gas. I switched plugs between cylinders 3 and 4 and the misfire moved. I replaced all the plugs and haven’t had a problem since.

    How difficult were the plugs to replace?

    The 4 towards the rear were easy. The front 4 were very difficult.

    P1303 came up on my 458 as well - I scanned it with a Bosch OBD2 reader.

    First I swapped coil packs and then spark plugs between cylinders 3 & 4, the code always comes back as P1303. There could be a vacuum leak, or a stuck fuel injector, or even a knock sensor faulty, but I'd like to know if P1303 is indeed a misfire in cylinder 3 or perhaps an altogether different fault? I don't have access to a Ferrari scan tool, so I'm relying on my off-the shelf Bosch reader that's why I'm not positive of the meaning of the fault...

    Does anybody have a list of CEL fault codes for the 458?

    Thanks!

    Do you have access to a Launch tool? Where are you located?
