MONDEO TXS 2.2 Posted January 9, 2016 Share Posted January 9, 2016 Could be a dodgy M.A.F. sensor - try removing & clean carefully with electrical contact cleaner, or replace it What condition is the air filter in ? Quote Link to comment Share on other sites More sharing options...
steve48 Posted January 9, 2016 Author Share Posted January 9, 2016 I was think the same thing. i replaced the maf sensor a couple of months ago witha cheap one because i thought my original one was shot but it wasnt, so i kept that original, i will put that back in hopefully that may help. would the egr blank cause this issue.

MONDEO TXS 2.2 Posted January 9, 2016 Share Posted January 9, 2016 Yes it would, I'd put the original M.A.F. back in. Unfortunately blanking the EGRV often illuminates the E.M.L. - but it's a small price to pay against the benefits of a blanked EGRV Quote Link to comment Share on other sites More sharing options...

iantt Posted January 9, 2016 Share Posted January 9, 2016 you need to check the intake shutter valve, that code relates to that. as your having running problems it sounds like theres and issue with the valve staying open when engine running, unplug the connector and check for corrosion. 1 Quote Link to comment Share on other sites More sharing options...

iantt Posted January 9, 2016 Share Posted January 9, 2016 At the bottom of the intake manifold, it will have a sensor or 2 fitted on to it, its right in front of you as you look at engine , there will be a connector to with wires for actuation. And position sensing. Pcm needs to know its open when running and shut with ign off. 1 Quote Link to comment Share on other sites More sharing options...
