Ford Kuga 2.0 2010 - DPF pressure sensor fault #

Posted by Neil Currie on October 3, 2015, 11:37 am

Year of Manufacture *: 2010
Engine Size and Code *: 2.0 DW
( Optional ) Scanner Used: IDS

Hi folks, This kuga has had a dpf issue for quite a while now and been looked at by other people before me.

As it sits with me looking at it, it has an new aftermarket DPF fitted and had 2 new genuine ford pressure sensor's tried aswell.

Every couple of months it will log an engine oil deterioration fault and oil will be above max on dipstick. If driven long enough it will log DPF faults aswell

Looking at numbers on IDS, the pressure sensor is reading high. Gauge on DPF i am getting under 1psi pressure from it so it is clean, Mityvac on pressure sensor it is reading 119psi in live data on IDS with 10psi applied so pressure sensor is over reading, but reads 0psi KOEO!

Wiring has been checked/load tested and all ok and vehicle is on latest version of software, monitoring signal output it reads ok no drop outs etc and goes up steadily with pressure increase.

I am thinking this vehicle has a software glitch and may need to contact Ford but just wondered if anyone on here had any tips? This vehicle has had a TSB carried out to move the sensor above the DPF onto rear prop carrier mounting plate as it is a 4wd version.

Thanks Neil

are you sure its reading 119 psi and not 119 kpa?

the 1 psi is this at idle or WOT

just a thought like , if you have them mixed up the tree you are barking up will no even be in the right park .

1 psi was WOT at front pipe of DPF and was under 1 really need a smaller gauge to get an accurate reading.

I am putting pressure into high pipe of pressure sensor and ref to atmosphere

IDS was set to psi if i change it to kpa it reads in the thousands, looking like a PCM problem, unsure how else i can prove it than replace/test it though!

not sure what else you can do ,however some times i create tests that are not even relevant , and then i lead my self astray.

so here is my thoughts on it, can you look at the dpf pressure sensor in say eobd and then graph it while you drive the vehicle,

you say its 1 psi at WOT( so this is 7 kpa) so in eobd it should display in kpa, drive the vehicle and see what the computer says in eobd, then do it again in the ford section , compare the two results, do they match, is eobd telling the truth and ford lying ?, are they both lying?

if the computer sees the correct readings move away from the pressure sensor, you have created a bad test, if the readings match your mitivac test i.e. 10 psi is seen as 119psi what more can you do?

Thanks for suggestion Andrew, never thought about using another scan tool as i am using the dealer tool. Will try another scan tool and see what i find.

Neil,

Had same issue about 6 weeks ago, Software update sussed it,

should see maximum 80-100mbar back pressure WOT in workshop.... (1.16psi - 1.45psi) for a clean DPF.

What fault codes do you have? if it has an aftermarket DPF is it possible it isnt getting hot enough / quick enough to carry out successful regen?

i never mess about with aftermarket DPF's.. we always obtain the original and regen before we proceed with diagnosing...

Hi Kris, DPF is clean (measured with gauge) but pressure sensor is reading so high, pcm thinks it is too high!

Can't remember codes now need to check tomorrow.

This car is on latest software aswell, tried another scan tool today and reads same as IDS so think next plan is send PCM for testing!
