OBD-II Check Engine Light Trouble Codes
Ford OBD-II Trouble Codes
It'll be the p codes (powertrain ones which you're interested in.

The slightly confusing thing is that no sites seem to list any codes which have the hex characters in them, but as the first three numbers indicate the component and the last one indicates the particular fault then at least you have a general indication of the problem. Also, not all the codes indicate a fault as such, merely a parameter, such as putting the car into a safe mode which obviously blunts the turbo's performance

Po1-a0 (indicates issue with air metering, so MAP or MAF)
P0248 Turbocharger Wastegate Solenoid B Range/Performance (to due with the turbo, I imagine this is it being put in safe mode)
Po5-05 [COLOR=#194e85]P0505 Idle Control System Malfunction[/COLOR] (I would imagine the MAF would cause this)
P11-01 Mass Air Flow Sensor out of Self-Test Range
P13-3c - can't find an exact code but the closest is P1309 which is Misfire Detection Monitor not enabled (I would guess this is a parameter set by the ECU whilst it's in safe mode)
P16-30 - can't really find anything for this either
P19-41 - Indicates something in the tranmission
P20-3a - Reductant Level Sensor A Circuit (no idea)

Points towards a MAF which a garage could clean if it's merely dirty. I imagine the codes are merely shot out in numerical order so there's no real way to see what happened first so to speak.

Makes a little sense with the turbo being put into safe mode as that's exactly what it felt like while I was driving it.

Been ok today too.

Personally I'd get it seen to, you don't want that to to happen when you pull into the fast lane and an Audi is steaming up behind at a million miles an hour. If it's the MAF sensor it's not the sort of thing that will sort itself out and it's likely to reoccur. Find a trustworthy local garage and they'll sort it for you for sod all.

All capitalisation is mine (well my phones)

You have an OBD2 reader in your phone?

The Ford will display its OBD2 codes on its multifunction screen.

I wish my POS was similarly equipped. It would put my mechanic out of business... .

It may well be. It's not something you find in the owners manual.

Most cars don't display codes on a multifunction screen. The 500 for instance doesn't show codes. Pretty much all post 96 cars do have OBD2 ports though.

As far as I can tell they cost about $100 around here. Not cheap, but considering my mechanic charges about $50.00 for a "diagnostic", and I've had this done at least twice in the last couple of months, perhaps I should consider the purchase.

It also helps if your car is equipped with a multifunction screen in the first place .

I'm definitely thinking about getting one or buying some Fiat software and perhaps a really cheap netbook and an OBD2 cable.

Some cheap stuff to be had from South of the border where all the hosers live No idea where to get one from in Canada eh

Mine has a multifunction screen but AFAIK it don't show codes on it

Thanks, I didn't realise you could get them that cheap (yes, most hosers south of the border will ship to Canada with minimal shipping costs, although I sometimes have a bugger of a time explaining to them that I have a postal, not a zip code ).

Dumb question: If I were to purchase a reader, where would I find the explanation of codes themselves? Are these vehicle-specific?

I managed to keep it going but at reduced speed but could still maintain 60mph but it felt like there was no power. Closer to home it accelerated away from standing starts fine but as soon as it got above 2k revs there was nothing there. Felt very much like the turbo charger just wasn't working at all.

However, I parked up for no more than 10 minutes and then went out again and the car drove perfectly well, power exactly where I would expect it and I could feel the turbo working.

What's going on?!

What age is the car - I have a 1.8TDCi SMax, and had something similar which turned out to be clogged fuel filter. Other possible causes are splits in the turbo air pipes - is there lots of black smoke when this happens (more than normal with a disiesal I mean!)

Mine bahaved very intermittently at first - some days it was woeful, others it felt normal. I was coming up for the 3 year major service anyway, so held out for that which does include the filter.

If you have a laptop you can also buy an ODBII cable with a serial port at the other end. A cable may cost as much as the reader, and of course you need to hunt down a copy of the software, which actually isn't too hard as there are a lot of free versions out there.

ODBII is federally mandated as a standard reporting code for all cars sold in the US (and I'd think it would generally apply in Canada as well) since 1996. While each maker may have their own diagnostic reporting the cars is also required to put out all the OBDII codes. There is a set of EODB codes for Europe as well, but I don't know how they're mandated or organized.

Because it's a standard, most code readers are preloaded with a small database that will list the code by name. If you only have the codes you can also look them up online. You would probably get an even better explanation of the code and its likely cause.

Big Box auto repair stores will often scan your car for free, as well. I don't know how it's handled in Canada, though.

I found the codes for Marks car just by googling. There are some manufacturer specific ones, but usually you can find them on the interwebs. Most of the codes Mark had were general ones

I think you get what you pay for though. The 30 dollar one will tell you the codes whereas the ones over 150 dollars might give you an explanation of what they mean. That said, you could just write them down and check on your PC
