: trouble code Q for Wayne
03-14-2006, 12:58 PM
Wayne, my CEL light came on the other day. i took the car to a local shop. they said it threw the following codes:
I only got a FS CAI installed. I'm not sure what these mean but i unplugged the battery for 15 minutes or so. CEL light didn't come on again but i haven't driven the car yet. i wish i had an Xcal.
thanks in advance for your help
Ford Focus Engine / Error Code P2274
P2274 = O2 Sensor Signal Stuck Lean - Bank 1, Sensor 3

This DTC may be caused by :
Manifold vacuum leak.
Disconnected or Damaged vacuum hose.
Restricted or Damaged fuel injector.

Do you need to know what they mean?

thanks for the link.
but i can't seem to find P2274 and P1111 codes in there.
should i look for p0227 or something like that?
03-15-2006, 12:12 AM
did you pull those codes using the instrument panel trick? I don't know what the p2274 is off hand, but the p1111 is insignificant...
all that P1111 code means is all parameters hadn't been self-tested during that drivecycle when you pulled the codes... you can ignore it, it doesn't throw a CEL and won't cause any driveability problems.

googling the words "p2274" and "obd" netted a pdf document for the 2003 PZEV from motorcraft... here's an exerpt
Sounds like you need a rear 02 sensor, or you are REALLY running lean!

Scott_SVT thank you very much for the info. I'll replace the rear O2 sensors. I got one more Q tho. Since the rear O2 sensors are for long term fuel efficiency, what happens if the O2 sensor is not replaced? worse fuel consumption?
once again thanks for the help.

p1000 is the duty cycle test, not p1111 which is "Intake Air Temperature (IAT) sensor intermittent high voltage" which may be the cause of the o2 sensor issues, also pointed to by p0114 which is "Intake Air Temperature Circuit Intermittent". Looks like you need to look at the IAT sensor and see if it is ok.

doesnt waynes tune disable the rear o2 sensor ?
03-15-2006, 07:54 PM
He does that on all new tunes, but he didn't on some of the early early ones.
03-15-2006, 08:59 PM
doh!! Daeron is right... I was thinking about the p1000 code, and didn't even look to make sure... sorry about that...
Yeah, definately go with checking the IAT first, then dealing with the rear (only one) 02 sensor if the fixing the fault on the IAT circuit doesn't also fix the 02 code

guys cel came on yesterday once again and it threw the same exact codes. p114, p2274 and p1111. i got the IAT and rear O2 sensors checked and they are okay. i wanna believe it's just a fluke but i'm not sure. what do you say?
05-31-2006, 11:39 AM
what mods do you have? everything plugged in all the way? might be something that simple...from there, i'd start lookin if one of your mods could be causing it
05-31-2006, 04:29 PM
Daeron the only mod i have is the FS CAI
as far as i could see everything was plugged in okay. i'll check again just in case.

Do you notice anything wierd happening with the car right before the CEL comes on?
06-01-2006, 01:30 PM
no i haven't felt anything out of the ordinary. i was driving normally before cel came on in both cases.
other than that i sometimes feel like the engine stalls for maybe a millisecond or so when a/c is turned on and i'm driving on the highway at 80mph on cruise control. haven't felt this in daily commute though. but it had nothing to do with cel as far as the timing is concerned. i always attributed this to a/c kicking in and sucking power from the engine.
i took the car to ford service, b/c it's still under warranty and i had a few small things like fuel gauge malfunction etc., and they took a look at the car and how it drives and found nothing wrong.
06-01-2006, 03:33 PM
so they did nothing about it? that was nice of them...
06-01-2006, 03:38 PM
they did nothing about what? cel? they cleared it and checked the IAT and rear O2 sensors.
i didn't mention stalling to them b/c as i said i assumed it was normal as it's been unusually hot around here and a/c was working all the time.
06-01-2006, 05:56 PM
i'd say take it back to them if those codes have shown up again...
06-28-2006, 11:03 PM
okay cel came on once again... but this time i noticed something that may help solve the mystery: cel comes on as i start the engine from cold start. in hind sight, previous cel's came on after cold start also.
as far as i know IAT sensor is used to detect a cold start. do you think persistent CEL after cold start definitely implies IAT is malfunctioning?
isn't IAT located in the MAF sensor? if i need to change IAT, does this mean i have to change MAF sensor?
if i take my car to ford dealer - still under warranty - they'll certainly try not to replace MAF under warranty because of FS CAI. altho i don't think FS CAI has nething to do with it. considering all this, i thought maybe before taking car to service, disassembling FS CAI and cleaning hoses and filters might help the situation? i'm going to have to clean filter sometime soon anyhow...
06-28-2006, 11:05 PM
Very possible...clean the MAF (pretty easy to do...do a search for the instructions) and see if that helps any.
06-28-2006, 11:24 PM
Daeron thanks for quick reply. i appreciate all your help.
i got one last question, somewhat unrelated. last time i was cleaning CAI filter i noticed something weird. at least one end of FS CAI hose - the end that hooks up to the filter - was bent somewhat obviously because of tightening the clamps too much. but when i was installing i couldn't have tightened clamps that much to bent a steel hose. do you think this would affect integrity of FS CAI? (not referring to IAT issue)
once again thanks very much
06-28-2006, 11:29 PM
Daeron sorry this last question was totally unrelated to hyp. ill. forum
on another note, i'm convinced at this point to buy xcal 2 with wayne's tunes. not only i'll gain performance but i can look at these codes myself w/o going to dealer or something.
06-29-2006, 08:57 AM
It shouldn't affect anything...not much goes through that hose but air, and not much of that either.
You'll be happy with Wayne's tunes on your car :)
07-12-2006, 09:43 AM
Daeron after cleaning filter of FS CAI and MAF sensor, CEL comes on again.
i'm buying an xcal2 these days so i'll check the codes but i'm sure it's the same codes again. i'm puzzled n confused as to what i should do. any ideas, suggestions?
i can take the car to dealer and have them check maf sensor but i doubt they'll come up with a solution. they'll say it's okay and it might be because of the filter.
maybe rear o2 sensor is malfunctioning but i dont think that would throw CEL, would it?
thanks for your help.
07-12-2006, 03:36 PM
CEL turned off on its own after less than 24 hrs. i have no idea whats going on here [???:)]
