CEL came on

Was driving home and all of a sudden the CEL came on. I think it may be the infamous loose cap since I had put gas in it prior to driving and I remembered I "clicked" it only once to close the gas cap. Question is how long do I have to drive in order for the CEL to turn off itself? Any fellow F430 owners have had experienced the same issue?

I'm not sure how long it would take to clear itself, but I would just tighten the cap properly, then find a friend with a code reader. Read the code to make sure it says something along the lines of an EVAP leak in the system, then clear it with the tool.
If you don't have a friend with the tool, you can buy one (they are not that much money, and good to have...especially with a Ferrari). You can also bring the car to an Autozone store, and borrow the tool for free. If you don't want to do any of the above, and you are in a rush, you can always turn the main battery switch in the front trunk, off. The only problem with that method is that the car has to go through the whole relearn cycle for the engine management systems, and you will have to punch in your radio code to get the radio working again. Plus, you will never know for sure that it was the gas cap causing the C/E light.
I would recommend just buying the reader for ~$80 (they have them from ~$20 - ~$150) so you can have it in the future. The readers that cost a little more can tell you in plain english what the fault was, without you having to look up the code, plus they do some other additional things. Accutron makes some nice units. Good luck, let us know what it wound up being.

Thanks for the information. That was the only issue that prevented me from using the main battery switch was the whole relearning process.

I am going to be purchasing a reader. Which model would you recommend. In the meantime I am going to be driving the car through a few cycles to see if it will go off on its own. Hopefully that does the job. The car is driving and sounding normal. Nothing out of the ordinary. I will keep you posted.

I would go with one of the Actron models. You really can't go wrong with them:
ActronŽ
I'm not sure about the newer models, but if you read through the specs and their capabilities, then price them (Amazon is usually a good place for that). Then pick the one that fits your price point and needs. Usually it's better to get a more expensive unit, but sometimes it will be a waste because it will have features that you may never use. If you have trouble deciding, let me know and I will try to help analyze the differences to help you out. For the purpose that you currently need it for, any model would work fine, but the better ones that are approaching maybe $100 will have a nicer display and be easier to read and use.
Let me know if you need further help. Also let us know what it winds up being at the end.

So the other night I went to fill her up with gas and this time I made sure I tighter the gas cap. After starting her up again, the CEL light was gone! So the gas cap was the issue the entire time. Now the CEL is not showing up anymore at the moment.

I still want a code scanner for any future issues. I will go with Actron as you recommend. I just need a model that is easy to read and has all the functions I need. I see they have 5 models on their website. Which one would be best? Thanks for the help up4speed.

I would check that it can read the Ferrari codes properly.

Good news just an idea but make sure the inner gas cap gasket is not damaged. That's enough to loose fuel pressure even if the fuel cap is tightened right.

hmmm...

How do these devices connect to the F430? is this the OBD interface plug that i've been reading about? if so, i thought only the SD3 or Leonardo systems could give reliable info about the F430 system? However, if 100 bucks could give some insight i'm in....well...as soon as i pick up an F430...

Cheng- By law, all the OBDII connectors under the dash must provide information on emissions related problems. True for Ferraris and all other US cars since Jan 1996 so emission checks can be performed. Ferrari tried to bypass this requirement and got their pee-pees whacked by the EPA, so they fixed the connector.

Here is a list of all the required codes.

OBD-II Check Engine Light Trouble Codes

Present: 575M 135171
Past: Dino 246 GT 02984, 365 GTB/4 14009, 308 GTS 25125

Every day I look around, and if nobody is shooting at me, it is a pretty good day.

OK, so the dreaded CEL came on again. This time I would assume it is not a loose gas cap. Decided to take it over to a local Ferrari specialist indy shop and get the codes read. Here are the following codes: P0139, P2188, and P1136. Also, he told me my exhaust manifold is blown and that it is covered under the 8 year emission warranty, is that correct? Please chime in, thanks!

So I will be taking the car to the dealership to get the manifolds replace. I was told that when replacing with manifolds, it should "solve" those three codes?

Replacing your exhaust headers is a good start to resolve your problems as a leaking header is a critical issue Consider upgrading the exhaust brackets with the Capristo suspended spring brackets to avoid them to crack again.

All the emissions codes are the same. It uses the OBD2 connector. These readers will check codes for EVAP leaks, misfiring, bad o2 sensor, etc. But be aware that it does not do Ferrari specific codes, for instance, TCU codes.
It would probably be best to call the manufacturer of the reader and have them explain the differences in their units to help you decide.

Good advice, I had the same issue with my car when I purchased it.

Yes, it only takes a few seconds to hook it up to the connector under the steering wheel. Every car after 1996 has that connector. I've used it on all my cars and friends cars and it is definitely a nice tool to have. The Sd3 can do way more, and it can also program different things on the car, but don't forget, you are comparing $100 to ~$20,000.

That's definitely a smart starting point since you have to do the manifolds either way.

I was totally unaware of the manifolds going bad but when I took it to a local Ferrari specialist, he said he can hear that the manifolds are bad because the engine noise sounded "rough". F430 manifolds are prone to go bad eventually sooner or later I guess. Read somewhere that the one fitted now are not that strong. The replacement manifolds should be much better or so I read.

Just dropped it off at Ferrari of Washington to get the manifolds replaced and the other codes checked out. Will update once I get a call.

Did you get a word from the dealer yet?
By the way, I was at Advance auto today, and Actron had an advertisement board to display their products. It explains the different functions of each unit that they had for sale. I attached the photo of the display, so it can hopefully help you choose. I would personally get the 9550 or the 9575, depending if I wanted to spend $90 or $130. If money is no object, the 9580a is real nice for $209. It does ABS codes and also gives the common fixes for each code! Of course that info would most likely be available on line, but it should make it easier.

I find it interesting that the first thing they always tell you to do when the CEL is on is to check the gas cap. When I bought my car, it came with NO cap. That's right, someone stole it somewhere while the car was in transit. I drove it for almost a month without a cap at all until I could get a replacement, and the CEL never came on.

Your ECU has been reflashed to disable the CEL With no or loose gas cap, a CEL will come up 100% for sure.

That's very strange. On any other car I've ever owned, the light would not come on. I used to even fill up the tank with the engine running!
With the Ferrari, as soon as the cap started to loosen, the CEL triggered. I was shocked that the light triggered that easily in the Ferrari.

I have no heard a word from the dealer yet, I will going to be contacting them soon. I wasn't aware that Advanced Auto sell the reader. I will probably be picking up the 9580a.

Asked the dealer about the fuel bars and he stated that above half, the sensor or unit for the fuel bars tend to act up, below half it will display a more accurate read.
