How to: Mk6 Fiesta Throttle body & MAF sensor

2005 Ford Fiesta non starter FIXED!

[@geoffdecorator307]

I have the exact same Fiesta with the 1.4 duratec engine and heres a tip for you guys ,get yourself a spare air box maybe from a breakers yard or keep the one off the car you may of scrapped earlier .Store it away somewhere and the night before you can change the filter at your leisure and simply switch over air boxes ,in my case i have a K and N filter in the car but keep a normal filter as a spare .

[@Nyle95]

Thanks, I gave the throttle body and MAF sensor a good clean today. My car does start but sometimes takes a second attempt or requires pressing the accelerator to get it to start, will see if this has helped. Which tool do I need to remove/reconnect the hose clips? I was able to get them off but wasn't able to reconnect the clips so have taken them off and fitted standard jubilee clips until I can find the correct tool. Thanks.

EDIT: I think I've found what I need; Clic R pliers

Hi should the butterfly valve completely close when u it detached. There is a 2mm gap on mine but closes more if I push it then it Springs back

[@valleysman1234]

GJDiary cleaned both sensor and they were really dirty still have the same problem is there a maf sensor around the air box thanks.

[@BugRacer1955]

As far as I know just the one maf sensor

[@florin-danieltomulescu]

Hello, i dus exactly the same as you did and now the idle is staying on 3k rpm. Do you know how I can reset it? It will work only with forscan?

[@BugRacer1955]

I think if your idle is revving that high you might have an air leak…?

[@KaOS3542]

How did you reset the car after unplugging the sensor

[@warriorsofwarmth]

Wat do u think the issue was in the end? Idle? Dirt or air filter?

[@BugRacer1955]

Not 100% but I think there is an air leak somewhere as the engine is over-fuelling

[@oOadziOo]

How did you reset the car after unplugging the sensor etc?

[@KaOS3542]

I do have a Eac Fail on my 2004 mk6, and i saw on the internet that it may be the throttle body. Any advices?

[@BugRacer1955]

Hi mate sorry just see your message, is it the 8v engine as that’s the only one with idle control valve? My advice take your time clean everything thoroughly with carb cleaner and use new gasket for the ICV

[@EdderzX1]

Need to do throttle body relearn after doing anything touching the throttle body at all, even just moving the butterfly valve. Search Ford Throttle Body Relearn

[@bencolley9627]

On the reset car will only run if I’m keeping the revs on will not idle itself just stalls. Like yours did in the video. What was your exact reset procedure please while everything’s on and your holding revs turn off ? And how long hold please

[@noahfreeman5377]

i have the same problem how did you fix?

[@jsmithkoko]

suppose if you keep wire connected and just sprayed and wiped senors,then put bolts back,wouldnt have to do that reset bit..just saying ,cos im just about to do mine at wkend

[@BugRacer1955]

Yes absolutely, see how it goes I found it easier to remove them

[@leeroylongshanks7221]

Just about to do mine at the weekend.. reset worries me a bit.. was thinkin the same leave it connected.. was it really awkward left connected?

[@mikesully110]

My 2005 MK6 fester is idling at 1500 RPM, going up to 2000 if I drive it around for a bit, going to try the throttle body / MAF sensor see if it sorts it. Haven't cleaned it or done anything other than change the oil in 2 years

[@BugRacer1955]

I would definitely try cleaning them can’t do any harm 👍🏻

[@ranjitzzz100]

Mine is the exactly same issue. Did your issue resolved by doing this? Please let me know.

[@mikesully110]

@@ranjitzzz100 cleaned the throttle body, didn';t fix it :( haven't checked the MAF sensor will give it a quick check tomorrow. otherwise someone said it might be the lambda sensor

[@ranjitzzz100]

@@mikesully110 I also cleaned throttle body but didn't resolved the issue. Ford service center guy said that the throttle body need to replaced. I have ordered it. Will receive it within 2 day. I will replace and update you if it fixed the problem.

[@eetherington]

Actually I don't think what you call the MAF sensor is a MAF sensor, it looks like an air temperature sensor so it can run rich when it's cold to warm the engine faster, like an old choke used to be. And if the TPS is the big bulky type maybe the maf sensor is combined with the tps

[@xxraffoxx3849]

its actually a MAP sensor

[@Emreofflover]

solved the problem i connect foscan software and reset pcm fiesta now running perfectly

[@BugRacer1955]

I’m going to download the for Forscan software soon, maybe show it in a video

[@Emreofflover]

@@BugRacer1955 do you have a elm327 odb adapter ?

[@BugRacer1955]

I don’t but I’ve just ordered one which should be here in a week or so

[@Emreofflover]

@@BugRacer1955 reset pcm is simple operation. First connect forscan and car. go to in the left menu (service functions). select (pcm reset all adaptations). press "run service procedure button" in the sub menu (like a play button) and follow instructions. process completed. The engine may run unstable in the first few rides after the reset procedure. because ecu in relearning loop Do you still have idling problem? on your fiesta ?

Hi, what did you use to clean the sensor?

[@BugRacer1955]

Hello Ash I think I used carb cleaner for the intake and white spirit for the sensor

[@Ashleyerriah]

@@BugRacer1955 okay. Thanks

[@bencolley9627]

Nvm kept my foot on the brake whilst accelerating got her into gear and went for a 20min drive then cranked heating and lights. After it cycled the gears a few times it remembered how to hold idle

[@jamieoff3]

Hi, I have the same problem on my mkv but mine does start but it is the rpm which is unstable and the car turns off after a few seconds if I don't help it by accelerating, do you have a idea what it may be? I have already cleaned the MAF but nothing

[@BugRacer1955]

Hi Jamie can you smell petrol? do you think it’s overfueling? Without seeing it I would start looking for possible air leak, start spray some water over your hoses see if you can see any bubbles...looking for a possible split hose. Go really carefully don’t let water get in your electrics.

[@jamieoff3]

@@BugRacer1955 Exactly I can smell gasoline! Where would I start to see? What do you think are the parts to check? Thank you for your reply

[@jamieoff3]

Which hoses exactly ?

[@BugRacer1955]

When you remove the air filter that pipe which goes into the throttle body I would have a look at for starters

[@jamieoff3]

@@BugRacer1955 I'll take a look tomorrow morning, I'll let you know if there's any news, thank you

[@BugRacer1955]

I think that the breather pipe your referring to, connect into the air filter box

[@john1559]

@@BugRacer1955 yes ,but what is it's purpose?

[@BILLCHRISTOY]

it takes the oil fumes of the top of the engine (camshaft and valve stems) by the airfilter back to the engine for burning.Thats why you see i a bit oily.

[@MrMaster2262]

🤣💦 the subtitles doesn't match what your saying, watched with no sound made it bit confusing.

[@Nyle95]

So I've found out that the petrol Fiesta doesn't have a MAF sensor, but had a MAP sensor instead.

[@BugRacer1955]

Hi Nyle depends which engine you have the MAP sensor (manifold absolute pressure) was only fitted to the 1.6

[@Nyle95]

@@BugRacer1955 Mines a 1.4 and has a MAP sensor and the one in the video is a MAP sensor too not sure which size engine you have

Thanks Finlay 👍🏻

Hi i have this problem. I clean map sensor and throttle body, but dont change idle problem. can you tell me how i am reset idle ? (sorry for bad english ;) )

[@johnsharkey1980]

If you DISCONNECT your battery leads and touch them together or bridge them for 2 mins (minimum) your car will empty all the residual power from its electrical system and perform a hard reset as soon as the battery is reconnected….the leads MUST be off the car and they MUST be touching each other
