demikai Posted December 17, 2013 Share Posted December 17, 2013 Hi all new to sight so just going to put my problem out there and hope for the best I have a engine management light on 2007 transit code relates to mass air flow sensor also rough idle I believe it's called hunting judders occasionally on low revs but no limp mode still drives fine I have cleaned the sensor and removed egr valve to clean that I noticed the egr valve has been blanked of any ideas would be appreciated Quote Link to comment Share on other sites More sharing options...
wase16ll Posted December 17, 2013 Share Posted December 17, 2013 have you checked condition of air filter Quote Link to comment Share on other sites More sharing options...
demikai Posted December 17, 2013 Author Share Posted December 17, 2013 Yes it's not old and quite clean definitly not the way it looks when it's time to service but I am giving it a full service tomorrow anyway putting egr back in also new gaskets Quote Link to comment Share on other sites More sharing options...
wase16ll Posted December 17, 2013 Share Posted December 17, 2013 check fuse 28 in engine bay fuse box, this feeds the mass air flow sensor and the intake air temp sensor...should be a 15a fuse. just to confirm its a 2.2 tdci....might be a different set up otherwise Quote Link to comment Share on other sites More sharing options...
demikai Posted December 17, 2013 Author Share Posted December 17, 2013 Hi yes it is thanks ok I will have a look now at update shortly Quote Link to comment Share on other sites More sharing options...
demikai Posted December 17, 2013 Author Share Posted December 17, 2013 Hi yes fuse 28 is ok although it is 5 amp not 15 amp it has a triangle with a ! In and a book type symbol for that fuse Quote Link to comment Share on other sites More sharing options...
wase16ll Posted December 17, 2013 Share Posted December 17, 2013 sorry, yes it should be a 5a, 15a is for petrol version for 02 sensors. i'll see if i can dig out some tests for mass sensor can you remember the exact code you got Quote Link to comment Share on other sites More sharing options...
wase16ll Posted December 17, 2013 Share Posted December 17, 2013 is the sensor a 4 wire or 6 wire sensor got a feeling it will be a 4wire, in which case i dont have any info on it to test Quote Link to comment Share on other sites More sharing options...
demikai Posted December 17, 2013 Author Share Posted December 17, 2013 No not exact code but I found out that blanking the egr on mk7 brings eml on And apparently gives maf fault so I'm hoping that will solve that but just can't understand the ruff idle Quote Link to comment Share on other sites More sharing options...
mick85 Posted December 17, 2013 Share Posted December 17, 2013 Maf sensor an egr on closed loop circuit I think egr fault always throws maf sensor fault at same time Quote Link to comment Share on other sites More sharing options...
wase16ll Posted December 17, 2013 Share Posted December 17, 2013 if the code for mass comes back after putting the egr back as it should (if your still going to do that) then check for air leaks after the mass as that would be unregulated air and give rough idle Quote Link to comment Share on other sites More sharing options...
demikai Posted December 17, 2013 Author Share Posted December 17, 2013 Sorry have the code it's p1103 Quote Link to comment Share on other sites More sharing options...
wase16ll Posted December 17, 2013 Share Posted December 17, 2013 thats mass, range higher than expected have never blanked a euro4 egr, so not sure if thats a code that flags when you do do remember though that there was a common fault with the fuel pressure sensor on the end of the rail....think they needed an update or something like that, but symptoms were rough idle and hunting...pretty sure this was specific to 2.2...not saying its your fault but might be worth looking into Quote Link to comment Share on other sites More sharing options...
demikai Posted December 17, 2013 Author Share Posted December 17, 2013 Yes going to put the egr back on do full service and clear codes and then if I still have ruff idle I will go from there I noticed it looked like the egr was swapping from were the blank plate had been fitted looked like oil leak but was coming from between gasket and blank plate don't no if that makes any diffrence Quote Link to comment Share on other sites More sharing options...
demikai Posted December 17, 2013 Author Share Posted December 17, 2013 Should I replace gaskets they look ok Quote Link to comment Share on other sites More sharing options...
mick85 Posted December 17, 2013 Share Posted December 17, 2013 Yeah I would agree with wase egr prob throw in on that fault an if u remove sensor an check it they come apart ford recommend replace that an imv valve at same time an that fuel rail sensor don't always throw on code or eml but when u replace this u need get pump learned again an u will be prob wanna check for PCM update aswell Quote Link to comment Share on other sites More sharing options...
wase16ll Posted December 17, 2013 Share Posted December 17, 2013 its possible as where the oil is leaking it could also suck in air. think they were metal gaskets so should be able to see if there is a problem...going by the oil leak, you might need to clean all the pipes out too as chances are they will be clogged before the blanking plate.

wase16ll Posted December 17, 2013 Share Posted December 17, 2013 that rings a bell, mick take out the pressure sensor it falls apart, and even if it doesnt they suggest new sensor and update....sure that was the 2.2 Quote Link to comment Share on other sites More sharing options...
demikai Posted December 17, 2013 Author Share Posted December 17, 2013 Sorry last bit of that message confused me a bit when you say replace sensor do you mean maf and somtware update Makes sense but what do you mean learn pump Quote Link to comment Share on other sites More sharing options...
demikai Posted December 17, 2013 Author Share Posted December 17, 2013 Yes mine is 2.2 Quote Link to comment Share on other sites More sharing options...
mick85 Posted December 17, 2013 Share Posted December 17, 2013 To be honest can't which member engine size just had that on transit no faults rough idle took out rail sensor broke up replaced with suction control valve(imv valve) on back of injection pump ford recommend but I have often just replaced rail sensor an PCM update Quote Link to comment Share on other sites More sharing options...
demikai Posted December 17, 2013 Author Share Posted December 17, 2013 Were will this pressure sensor be located thanks for all help Quote Link to comment Share on other sites More sharing options...
demikai Posted December 17, 2013 Author Share Posted December 17, 2013 Would there not be a code if the Imv had failed (broken up Quote Link to comment Share on other sites More sharing options...
wase16ll Posted December 17, 2013 Share Posted December 17, 2013 sensor is on end of fuel rail, take off the air filter casing and you will see it Quote Link to comment Share on other sites More sharing options...
