Jimmy lyons Posted May 2, 2021 Share Posted May 2, 2021 I'm having problems with Mk4 2.0 HDCI Zetec 2009 Mondeo, I was getting fault code P2263 and going into limp mode especially when going uphill or under hard acceleration. I have replaced turbo boost solenoid, actuator sensor, MAP sensor, MAF sensor, Air intake temperature sensor and the ICP pressure sensor. I've also used Revive turbo cleaner, the limp mode seems to be fine now however I'm getting P003A fault code and the car is jerking in 1st and 2nd gear sometimes in 3rd. I'm needing help in identifying the cause and cure for my problem any help is appreciated jimmy Quote Link to comment Share on other sites More sharing options...
Gaskell71 Posted May 3, 2021 Share Posted May 3, 2021 https://www.dtcdecode.com/Ford/P2263 http://enginedtc.com/p003a-ford-mondeo I'd be tempted to clean your EGR, checking all your fluids for leeks and levels, reset all the codes and take for a good run keeping over 2k rpm for a good few miles. Good luck with your Mondeo, it's just what I found with Google. Quote Link to comment Share on other sites More sharing options...
Jimmy lyons Posted May 7, 2021 Author Share Posted May 7, 2021 Thanks Gaskell71, I started to clean egr valve but unable to get to the bottom bolt, I've have cleaned the egr to inlet manifold pipe and noticed a slight improvement. So I have now inserted a blanking plate on the same pipe and the car is acting brilliantly so far with no hesitation, I only want to use this as a temporary measure until I can get that bottom bolt off and give the egr a proper clean as that seems like the cause of my problem. I'm not sure what size the bolt is or how to gain access to it Quote Link to comment Share on other sites More sharing options...
Gaskell71 Posted May 7, 2021 Share Posted May 7, 2021 I think that bolt is a 5mm hex, if you've got a swivel bathroom mirror for shaving that fit below to spot the bolt. Once that bolt is removed throw it away, even Volvo don't bother fitting that underneath bolt. Dipetane is a good addative if your ever looking for one, Im trying a bottle now and cold engine performance has definitely improved with far less black engine oil from soot too.

Jimmy lyons Posted May 20, 2021 Author Share Posted May 20, 2021 thanks Gaskell 71 got egr off cleaned and have used eco max in the tank and the car is running great and quiter. Took your advice and tossed the 15mm hex away took me an hour to get it off.👌 Quote Link to comment Share on other sites More sharing options...
