P2002 pressure sensor fault?

Featured Replies

Brand new here, hope someone can help me! 

I have a 2022 Focus ST 2.0 ecoblue, getting fault code P2002 coming up (no other codes) and think I have narrowed it down to the Dpf pressure sensor as car does plenty of long motorway runs, before i swap this out, pretty sure this will have come up before but is that a likely issue? Also is this picture the dpf pressure sensor? 

Appreciate any help with this 

 Cheers,

Welcome!

It should have (normally) 2 pipes BUT the sensor may well be giving you a message that the DPF is blocked/becoming blocked.

Suggest Forscan and lead (if you don't have a reader that can do it) to monitor the differential pressure and find the fault from that point.

You'll need to post the pressures at idle and 3000 rev/min and any other details.

Assume this 2022 doesn't have vaporiser plug so there must be another fault causing this issue (once you have looked more deeply and providing the sensor is reading correctly)

Thats my reading based on the current info...

Thanks for the reply, have been out this morning and looked at idle and 3000  rpm, is the picture below the right values I’m looking for? Open loop is sitting at 85% IMG_0266.thumb.jpeg.dabd40c6d90b2b64821881936d22aead.jpeg

1.72psi at 3k rpm stationary is high.  0.21psi at idle is acceptable.  To me that looks like the sensor is working and the DPF is genuinely quite full. 

I'd probably run a static regen to see how much the pressure drops afterwards, though I know many on here aren't keen on them.

Have just been on a 200 mile round trip, kept the car in high revs for some of it. 
 

values are now 0.12 at idle with around 1.1 at 3000rpm.

closed now says 25% and open 67% so looks to have come down.  

do we reckon this is just blocked and needs cleaning or static regen? 
 

thanks for any help here

Is the fault still present?  The 3k figure looks acceptable to me now. The DPF does slowly fill with ash over time so we're not looking for a perfect 'as new' figure on a 3 year old car.

A good italian tune up every now and again is no bad thing !
