Saintgeorge234 Posted April 28 Share Posted April 28 Hello, i have a 2018 3.2 Ranger which is in limp mode and is showing a full Dpf, with codes of P246c and p2463 , i only have 30 miles before it wont start any more. The Dpf has been cleaned by a mechanic friend, but i fear he is stuck for the next move as the codes wont clear. It starts on the button and sounds sweet , we have also replaced the Adblue pump which was broken. Can anyone give me any clues as what to do next i can do most things mechanical so was thinking of removing the Vapouriser first and cleaning that. Thank you.

Saintgeorge234 Posted April 30 Author Share Posted April 30 Hi Unofix' thanks for the reply, we have first tried a Dpf fluid cleaner down the pipe that connects the pressure sensor, . Quote Link to comment Share on other sites More sharing options...

TomsFocus Posted April 30 Share Posted April 30 Is the 30 miles to no-start for the DPF fault? I thought that was only for AdBlue faults? Has the DPF pressure differential been measured on diags? If so, what sort of figure is it showing? 2 Quote Link to comment Share on other sites More sharing options...
Saintgeorge234 Posted April 30 Author Share Posted April 30 hi Tomsfocus, i,m learning as i go, still waiting for mechanic to pressure test it, but dashboard warnings say Adblue system service required to start engine,Reduced engine power, See manual, and Adblue warning sign.It did say DPF filter blocked , but that has now gone.!

It seems like the system needs reset. If you check the AdBlue level on the instrument cluster does it show the tank is full ? 2 Quote Link to comment Share on other sites More sharing options...
Saintgeorge234 Posted May 1 Author Share Posted May 1 Can you tell me how to do that or can i find it in the handbook, thank you. Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted May 1 Share Posted May 1 This is the handbook page for Adblue. It looks like the light can't be reset by the driver, though I have no personal experience with Rangers. Fuel and Refueling - Selective Catalytic Reduction System (fordservicecontent.com) You can try one 'bodge' - switch the ignition on (but leave engine off) and then grab the truck bed and give the truck a shake side to side to activate the level sensor in the tank. As you've had a new pump fitted, that may need to be primed using Ford diagnostic software before the 'service' light will go out. If it was mine, I might be tempted to drive it a short distance, say 5 miles, to see if it resets itself. I have seen Adblue range counters that take a few miles to reset, but as yours had a fault as well, I can't say for sure that it would work in this case. 1 Quote Link to comment Share on other sites More sharing options...
Saintgeorge234 Posted May 1 Author Share Posted May 1 Tomsfocus, thanks for trying mate i will give it a go, it seems like these whole systems are a real minefield of vaying possibilities,even doing research on Youtube shows you that people have no real clue how these systems work. Even the smallest link in the chain to fail will send the car into potential shutdown but you end up chasing your tail changing parts that dont need it.

iantt Posted May 1 Share Posted May 1 How did you come to the conclusion the adblue pump was broken? That would have brought up another dtc for adblue low pressure? Ford diagnostics should pinpoint the issue easily enough. With the diagnostics you can reset the miles to shutdown so that a proper road-test can be carried out after component replacements. Allows the dpf to get a proper regen if the fault has been fixed. 1 1 Quote Link to comment Share on other sites More sharing options...
Saintgeorge234 Posted May 1 Author Share Posted May 1 The little nozzle that exits the pump was snapped off, and its an obvious weak point as it has wiring and pipe work connecting to it that seems to have been clipped up too tightly at the factory. Also i am a diy fixer and am trying to remedy the issue without being striped up at a main dealers or anywhere else. I have always tried to fix things myself.

Saintgeorge234 Posted May 8 Author Share Posted May 8 Further to advice, i took the ranger for a drive and after about six miles a dashboard message read { Filter cleaning } so according to the handbook thats exactly what it is doing of its own accord. Next day i cleared the codes with a basic OBD11 codereader and went to put more diesel in, and it came out of limp mode and the EML and Adblue warning lights dissappeared. Carried on driving for about 30 minutes Ranger now on full power and at present all seems back to normal. I realise this may be temporary so i will post again if something occurs. Thanks for all the advice up to now. 1 Quote Link to comment Share on other sites More sharing options...
Saintgeorge234 Posted June 9 Author Share Posted June 9 One month later and all seems well apart from one code keeps being thrown up, P204F, which could be a few things so might be hard to pin down. Eg, Adblue tank heater - Wire problem - Reductant pressure sensor, ! Any help would be aprecciated , Thank you. Quote Link to comment Share on other sites More sharing options...
