unofix Posted December 20, 2022 Share Posted December 20, 2022 Hi Guys, just after a bit of confirmation of the following problem on my daughters Kuga with 50120 miles. Has just come up tonight with the red warning triangle "Engine Malfunction" the car is still driving fine and is not in limp mode. P2456:92-2F P2452:12-27 P2452-P U1900-20 FORScan diagnostics below. Do you think I'm right to assume that this is going to be just a faulty Particulate Pressure Sensor ? Quote Link to comment Share on other sites More sharing options...
Tizer Posted December 20, 2022 Share Posted December 20, 2022 That does seem likely, either that or the wiring to the Sensor. I would bring up the Differential Pressure in Live Data and see what it says before starting and running and take things from there, and give the wiring a good wiggle to see if that kick starts things or makes them worse. 1 Quote Link to comment Share on other sites More sharing options...
unofix Posted December 20, 2022 Author Share Posted December 20, 2022 Thanks for the reply @Tizer I'll check out live data in the morning. This is the link to Kuga exhaust system. https://ford.7zap.com/en/car/56/code.ar,1.19571,2.42772,4.28899,6.42250,7.6034,10.16271,12.37222,13.32959,15.37658/26/1562/15611/68185/#5H209B Am I right to suspect that the sensor is ident (5H209B) Ford part 1786775 ?

That seems to be the correct part and they are not very expensive. I don't have a wiring diagram for that car but at a guess and following convention, the middle pin is probably the Signal wire if you feel like checking the wiring out after you look at what the Live Data says. 1 Quote Link to comment Share on other sites More sharing options...
Frembrit Posted December 21, 2022 Share Posted December 21, 2022 Looks like pressure sensor to me. I changed the pressure sensor on my friends 2010 Kuga a few years ago, although it also knocked out the Haldex unit due to multiple failed regens. I just happened ot have a spare used sensor as I replaced it on my Mondeo when I was troubleshooting dpf problems. Same part and it's mounted on the side of the battery box on the Kuga, which made it easy. 1 Quote Link to comment Share on other sites More sharing options...
unofix Posted December 30, 2022 Author Share Posted December 30, 2022 Well good news (I think). Finally got the new DPF sensor today and fitted it, which took only about 20 minutes. I cleared the DTC's and reset the DPF learnt values. Then off for a half hour drive on the motorway at between 60 and 70mph. Took a couple of photos of the live data (ones a bit out of focus 😧). The car seems happy 🎉 and no EML or warning bing-bongs. 3 Quote Link to comment Share on other sites More sharing options...

I don't know how high the Differential Pressure went when driving at the end of the journey but I would say that she needs to do a bit more driving to get the DPF cleaned out a bit more, 0.4 at Idle is ok but a bit on the high side and the Implied Soot and Ash levels are a little high as well. You could probably do a Static Regeneration but it would be better to just let it happen naturally while driving. 1 Quote Link to comment Share on other sites More sharing options...
