Normally it's the sensor at the CAT that will cause this. But I agree with Basil, take it to a Ferrari guy and let him diagnose and repair it for you. Better spend a bit than try to be smart and end up witht a big bill.
Do you have an sports exhaust system , and therefor removed the catalycators?
If thats the case, you just remove the plugg from the (brain)on each box were the sensors from your exaust pipe are connected. Because this warning light is for protecting your catalysators.
If you have catalysators, check your sensors and their connection. You can try to take them out of the exaust pipe and rubb them with a fine sandpaper and put them back.
Thanks, I have a tubi stainless exhaust but left the cats in place. I pulled off the MAF sensors and reconnected as well as a couple of other easy disconnects and now it seems to be running fine. I'm not sure if it was a loose or bad connection or if it was just dumb luck.
