Differential Pressure Sensor 994 mbar

[shafty]

Hi all
was messing about with the motor today trying to sort the fap out, turns out that the differential pressure sensor reading is 994 mbar, when i unplugged it it still read 117 mbar, surely not correct. Also I was planning to reflash the ecu but I couldnt get galletto or kwp to even see the ecu (edc15).

Car is citroen c8 2.2 hdi, thought id ask here as this place seems more informative than any cit forums.

Thanks

117mbar is the fail safe if the sensor stops working it will still regen , did you check dpf parameters to see what load was?

Thanks for that info, so i guess a new sensor is needed then, cant remember the load but it has all been reset to 0.

TBH its doing my nut. The fap has been removed and cleaned, the eloys tank is quite full (removed and actually had a look), I think perhaps the eloys pump may also be shot. Any idea on the ecu flash problem?

Its coming close to being attacked with a hammer.

Save up and treat yourself to a proper remap

Might not be a new sensor, one of the sensor pipes might be blocked, causing a high diff pressure

the differential pressure sensor does give quite a bit of bother on them

hey shafty, just curious, could you post the pic or something of the location where the pressure sensor is located. i wanted to check mine too, but for the life of me i couldnt find it.

Sorry I would post a pic but its removed from the car for the moment, to find it simply follow the 2 rubber hoses that conect to the metal pipes on your cat and dpf, the little plastic unit they connect to is your sensor.
