fault dtc pressure sensor fap

[michell]

has anyone ever removed this type of error pressure sensor fap..su a freelander 2.2td4 150hp 2007???
I'm attaching the file, and the errorei ...,,I'm depappando and I would not conprere sensor failure...thanks

hello,these are a bit nasty and you have to follow procedures before with a forced regeneration and erase DTC errors etc..before that processes the file ori if you can also replace the fap,you have these errors x, which of course you have the filter clogged and the sensor records a lot of pressure, to delete the dtc you have to detach the pipes under the differential sensor go in the diagnosis and gates of all,you need to check the hoses if they are free, if ok, colleagues all, of course, you have to drill holes in the Fap!!

thank you for your answer,,,,I have done this procedure ....I did the replacement of the fap in the diagnosis then I looked at that I was carrying particles 0
and I tried to delete the errors .....not me, told them to take off....but I have uploaded the same file already defappato,,,,and everything is ok...now I'm driving to try it
and ? everything is ok...of course I also made the holes......what do you think I'll have problems?????

at the moment you will not see the need to do a bit of km, the safety you'll only be doing the km,the particles to 0 you have checked only the minimum you need to check the max accel...this procedure is done before reading the file, you did the forced regeneration??need diagnosis of the mother house to make the RIG. Forced.. I repeat to eliminate the errors of the differential sensor you have to disconnect the hoses, then go to erase the dtc in the diagnosis clean the pipes and hang up all,if' no', then follow the procedure to the letter cancels them ever,I'm sorry, but as you did the work ? done at the met?!!

that ecu mounts? with which tool you made?

with f.g. official if you want to get the data downloaded in the zip file......anyway edc16cp39

ragazzio I on these engines, I switch to another system, in addition to the file svappato and the regenerations to lower the ****llo clogging in the outlet of the sensor for differential pressure and aplico a resistance of about 35 ohms in the mode that diagnosis to bring me a pressure differential is close to zero, with this change, no one has nessuana failure.. hello

The sensor in an original take, or the resistance is put in series ?

interesting you think you can apply on other engines as jtdm?

if you get the chance do the test and post the results,the beautiful and' share i.e., the user Backgroop has shared his method you have acquired a new figure and you can apply it on a different drive,then put the result here and hoping it is positive, we all have a new data to put in our technical knowledge.

I ask why? in some ways it would seem the principle of "emulator" of the lambda probe, which are used in some cases on cars and petrol.
I thought that the sensor of the FAP/DPF to be something more? sophisticated...

[Backgroop]

The sensor differential pressure should be left... the resistance should be connected between the negative and signal wire.. the operation of the sensor as a variable resistor to vary the pressure, the cio? pressure and resistance sn directly proportional.. the principle and one of the emulators, but only that in this case, the pressure differential will be forced to zero.
