Luke4efc Posted May 17, 2020 Share Posted May 17, 2020 Dash codes are useless, you need the ones from the code reader. Are your journeys mostly around town with stop/start traffic? Or do you spend a lot of the time on the motorway? Quote Link to comment Share on other sites More sharing options...
ozzy610 Posted May 17, 2020 Author Share Posted May 17, 2020 Mostly stop start but do about 250 miles a week like that. Quote Link to comment Share on other sites More sharing options...
Frembrit Posted May 17, 2020 Share Posted May 17, 2020 Blocked Fuel Vaporiser is the most likely cause...that's why it won't do a static regen as it cannot spray extra fuel in to the exhaust to get the temperature up to 600 - 650 Celsius Quote Link to comment Share on other sites More sharing options...
ozzy610 Posted May 17, 2020 Author Share Posted May 17, 2020 How do I clean the vaporiser.is the liquid solution or is it a strip out. Quote Link to comment Share on other sites More sharing options...
Frembrit Posted May 18, 2020 Share Posted May 18, 2020 If it's blocked then the easiest thing to do is to replace it; they're about £250 for the part only from Ford or about £120 on eBay...https://www.ebay.co.uk/itm/GENUINE-FORD-DPF-FUEL-VAPOURISER-VALVE-FITS-FORD-FOR-FOCUS-C-MAX-MONDEO-2-0-2-2/202271441339?hash=item2f185141bb:g:xeEAAOSwUVFcWq6W whoever replaces it needs to plug in to the car and reset the DPF Learned Values and other Error codes, then take it for a drive on a free flowing road (A road / dual carriageway) and it should start to perform regen after a few miles. It blocks up due to the build up of carbon inside the vaporiser unit, and to clean it would involve removing it from the exhaust pipe and spending time trying to scrape it clean internally through a tiny hole (which won't work) or by removing the glow plug which is possible and this is what I did when I tried to clean mine, however it didn't work. It's also possible that the glow plug could be on it's way out too. Changed mine 3 years ago and it's been fine since, though I regularly use premium diesel now.

ozzy610 Posted May 19, 2020 Author Share Posted May 19, 2020 Car went in to mate garage again.this is what the scan said.now the scan cant clear the codes.just keep coming back.the car has no loss of power. Quote Link to comment Share on other sites More sharing options...
Frembrit Posted May 19, 2020 Share Posted May 19, 2020 The "catalyst temperature too low..." basically means it can't get up to 600+ degrees celsius required for the regen, which means the vaporiser is not working (probably as I described above), this is a common problem and happens on the Transits too (exact same vaporiser). If it was an electrical fault then it might say something like "Exhaust aftertreatment glow plug open circuit..." meaning disconnected or glow plug failure (in the vaporiser). You can't clear them because it wants to (needs to) do a regen, so even if you did manage to, they will come back within a few miles of driving, meanwhile the dpf is getting more clogged (ref: Soot accumulation error). If his snap-on machine is capable, try and reset the "dpf learned values" and then try to clear the errors, but once it's re-calibrated itself again you will get the same errors when it tried to regen again. You might be lucky and it might regen (did this on my car a few times before eventually it wouldn't and went in to constant limp mode), but this would be temporary until it blocks completely.

ozzy610 Posted May 19, 2020 Author Share Posted May 19, 2020 Ok so garage is gonna strip exhaust and see if the vaporiser is working and if not get a new one as it is impossible to clean.he gonna use forscan and make it inject fuel in to check..is that correct thank.

Frembrit Posted May 19, 2020 Share Posted May 19, 2020 No need to strip exhaust, just remove the vaporiser, it will be obvious if it's blocked, the hole will be bunged up and you won't be able to blow through it from the fuel feed pipe.

Gusti Posted May 16, 2022 Share Posted May 16, 2022 Hello, I'm not opening new topic... I have problems with Exhaust gas temperature sensor. P0544, P0546 I changed sensor 1 and sensor 2 and I'm still having yellow warning light. Any ideas? Thanks Quote Link to comment Share on other sites More sharing options...
