pragmatix Posted May 8, 2016 Share Posted May 8, 2016 (edited) I've got an interesting one intermittent EML no loss of performance, fuel economy good 55ish, car does long runs shortest is 23 miles, I can't nail down the point the EML comes on it just pops up, It resets using Forscan and can stay of for 200 + miles or can come on in as little as 5. Can't find any physical faults, EGR is clean, hoses to sensors intact, done a static regen forscan screen image attached Edited May 10, 2016 by pragmatix Added missing image Quote Link to comment Share on other sites More sharing options...
pragmatix Posted May 10, 2016 Author Share Posted May 10, 2016 Any ideas, could it be an electrical fault, I've had a history of those. It's a 57 plate 2 ltr tdci with 165k on the clock Quote Link to comment Share on other sites More sharing options...
iantt Posted May 10, 2016 Share Posted May 10, 2016 have you checked the pressure sensor hoses for splits at the dpf end? Quote Link to comment Share on other sites More sharing options...
iantt Posted May 10, 2016 Share Posted May 10, 2016 could be a faulty pressure sensor, thats not uncommon Quote Link to comment Share on other sites More sharing options...
pragmatix Posted May 10, 2016 Author Share Posted May 10, 2016 Yep no splits in the hose, so it may be the sensor, kinda makes sense, if it was the hoses I would expect the fault all the time. Quote Link to comment Share on other sites More sharing options...
iantt Posted May 10, 2016 Share Posted May 10, 2016 check the part number stamped on the sensor, i might have a 2nd hand about somewhere you can try if its the same. Quote Link to comment Share on other sites More sharing options...

NPN Posted May 14, 2016 Share Posted May 14, 2016 Hi, could you tell me what voltage are present at the plug going to the dpf pressure sensor ? There are 3 wires : 1x 5V (or near), 1x 0V (Ground), and you must check the last. Very easy : the black probe of your Voltmeter in the middle terminal of the plug (Gound), then probe the 2 others. It takes 3min to do. Quote Link to comment Share on other sites More sharing options...

NPN Posted May 16, 2016 Share Posted May 16, 2016 It's under the hood, near the wipers. Quote Link to comment Share on other sites More sharing options...
pragmatix Posted May 16, 2016 Author Share Posted May 16, 2016 Ta have had a look but not sure what I'm looking for, not clear in the Haynes manual Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted June 7, 2016 Share Posted June 7, 2016 that seems more like the particulate filter needs a regen? Quote Link to comment Share on other sites More sharing options...
pragmatix Posted June 7, 2016 Author Share Posted June 7, 2016 I've done a static regen, according to Forscan the operation was completed, most of my miles are mway at mway speeds I.e. Not 70 Quote Link to comment Share on other sites More sharing options...
Tdci-Peter Posted June 7, 2016 Share Posted June 7, 2016 If that is the only error code, it sounds pretty specific that either the dpf is partially blocked, or the pressure sensor is reading high for some reason. Perhaps you could try disconnecting the hose(s) from the sensor, see if it then says the reading is too low. If so, it must be the dpf, or the hoses to the sensor. If it still reads high then it almost has to be the sensor. Quote Link to comment Share on other sites More sharing options...
pragmatix Posted June 8, 2016 Author Share Posted June 8, 2016 I tried to find the sensor but couldn't , not sure what I'm looking for, NPN said its near the wipers, that's the only clue I got. Quote Link to comment Share on other sites More sharing options...
Tdci-Peter Posted June 8, 2016 Share Posted June 8, 2016 I think the sensor looks like this. It should have two small hoses that find their way down to the DPF unit on the exhaust.

pragmatix Posted June 8, 2016 Author Share Posted June 8, 2016 (edited) Ta will take a look, had a look can't see anything like that on the bulkhead in the engine bay, Edited June 8, 2016 by pragmatix Now looked Quote Link to comment Share on other sites More sharing options...
Tdci-Peter Posted June 8, 2016 Share Posted June 8, 2016 It is looking to me as if the sensor is in the left hand front wheel arch, behind the wheel arch trim. The type & pictures in this manual are tiny, I can barely read it, but it still looks fairly clear. See: http://workshop-manuals.com/ford/mondeo_2007.5_02.2007/mechanical_repairs/3_powertrain/309_exhaust_system/309-00e_exhaust_system_2.0l_duratorq-tdci_(dw)_diesel/description_and_operation/removal_and_installation/diesel_particulate_filter_(dpf)_differential_pressure_sensor/ Also I have extracted two pics from it: Quote Link to comment Share on other sites More sharing options...
pragmatix Posted June 9, 2016 Author Share Posted June 9, 2016 Thank you, that kinda makes sense, will have to get a set of wheel arch trim clips before I look at that, from past experience they are a one shot use, or maybe they are just old on my car 1 Quote Link to comment Share on other sites More sharing options...

pragmatix Posted July 9, 2016 Author Share Posted July 9, 2016 No not had chance to look, been ill and have a new puppy so not had time, thanks for asking. Quote Link to comment Share on other sites More sharing options...
iantt Posted July 9, 2016 Share Posted July 9, 2016 why I ask is that it could be in 2 postions, either behind wheel arch liner as previously described or low down on bulk head like this one I found. to the left of battery hiding behind the scuttle panel drain hose, pushed drain hose back so you can see 1 Quote Link to comment Share on other sites More sharing options...
pragmatix Posted July 9, 2016 Author Share Posted July 9, 2016 Thanks that's very useful info, at least that's easy to look for. Quote Link to comment Share on other sites More sharing options...
pragmatix Posted July 12, 2016 Author Share Posted July 12, 2016 Sensor is not on the bulkhead, so must be behind wheel arch Quote Link to comment Share on other sites More sharing options...
iantt Posted July 12, 2016 Share Posted July 12, 2016 unlucky ford must have decided under arch liner was not such a good idea by 2009 Quote Link to comment Share on other sites More sharing options...
