Mr Pink Posted April 9, 2015 Share Posted April 9, 2015 Hi I'm hoping that someone can help me out with an issue that I'm having with my Focus Zetec 1.6 Diesel (2009), was having an issue with the car losing power and having no grunt. after awhile the engine management light came on and after looking at the error code (P042F) EGR Valve stuck closed, the EGR Valve was replaced. but a few weeks later I am having the same issue, at times I have no good acceleration just seams heavy, then last week the engine management error reappeared but it is a new EGR valve that has been installed. can anyone help with what the issue could be? thank in advance Quote Link to comment Share on other sites More sharing options...

iantt Posted April 9, 2015 Share Posted April 9, 2015 That needs doing after fitting new valve the closed position needs configuring to the pcm ,cooler should have been checked for blockages also Quote Link to comment Share on other sites More sharing options...

martyntdci Posted April 15, 2015 Share Posted April 15, 2015 block it off. egr valves are more trouble than good....... Quote Link to comment Share on other sites More sharing options...
Mr Pink Posted April 17, 2015 Author Share Posted April 17, 2015 Hi After driving the car yesterday noticed that the issue is still there, partly through my journey (I do 43 miles to work) I have no acceleration and even can slow while going up hill, this is with my foot fully down on the pedal. the EGR error has only appeared twice in 3 months (once since it has been replaced), so is it possible that the error caused from a different issue? thank you Quote Link to comment Share on other sites More sharing options...
martyntdci Posted April 17, 2015 Share Posted April 17, 2015 blank it anyway lol Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted April 21, 2015 Share Posted April 21, 2015 Blank it off for a start but do you get black smoke on heavy acceleration? Quote Link to comment Share on other sites More sharing options...
Mr Pink Posted April 21, 2015 Author Share Posted April 21, 2015 Hi no i'm not getting smoke Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted April 21, 2015 Share Posted April 21, 2015 In which case it's not likely to be a split hose. I suspect though the egr was replaced I suspect it could be related to the cooler Quote Link to comment Share on other sites More sharing options...
Mr Pink Posted April 30, 2015 Author Share Posted April 30, 2015 Hi sorry for not responding been away for work, thank you for info, is all of that cheap and easy to look at and deal with (i dont have much spare cash and im not much of a macanic) Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted April 30, 2015 Share Posted April 30, 2015 To be honest get a decent blanking plate on there and you will notice an improvement. When was the car last serviced? My cmax I had the egr blank installed, then took it for a service after I replaced the intercooler pipe, my mpg almost doubled and the power the same. It's worth doing it though. If you don't have much cash, check the pipe isn't split, then bung an egr blank in place and do a basic service. Take the vat to kwik fit for an oil and filter change if you can't do it yourself, then replace the air filter. Do it yourself and the cost could be around 30 all in, take it to kwik fit and it would cost about 70 all in, but I believe these combinations would help you. 1 Quote Link to comment Share on other sites More sharing options...
Mr Pink Posted April 30, 2015 Author Share Posted April 30, 2015 Thank you service was last year about august. In February the egr value was replaced and the cambelt and pump where replaced. I will look into blanking plate ago. Starting to hate all these senors in cars, keep getting p042f pending error (purchased a diagnostic machine) and i have to keep resetting the error to get out of limp mode. It was that error that made me get the egr value replaced, and now looks like it wasnt an issue. Quote Link to comment Share on other sites More sharing options...
TONTODAVIS Posted November 30, 2019 Share Posted November 30, 2019 Hi Lads Tonto Here I am working on a 2010 focus right now I have just replaced the egr valve as the car was cutting out , and the same as you guys I have cleared the faults and drove on . The car is now not cutting out and will drive but the light came back on and the code P042F , I made a call and another mechanic had similar fault and upon further tests . He reckons he discovered the Air flow meter was wanked and sending the{ EGR THE WRONG DATA }{COULD THIS BE THE CASE ? } . I have no black smoke so rulling out intercooler or split in intercooler pipes . power seems to be slowly increasing {so is it learning ?} or does this hep just need a good hard drive on the open road for the EGR TO LEARN . { OR WILL IT HAVE TO BE PROGRAMMED BY FORD ??? } Kind Regards TONTO Quote Link to comment Share on other sites More sharing options...
