A simple voltage divider?

Hi my old friend...
I was probe but is not good.
I must replace sensor on some car witch give precise 1.00V when conditions of some DPFE filter is ok...
Voltage divider work fine but is not temperature enought stabile.
ADin on car ECU measure in 0.01 V steps...
When I have 1.00V that is 0.2KPSA precise and car work fine..
If I have 0.999V that is not good ! or 1.02V is bad too ...
Sorry for bad English...

Sorry for bad English...Serb. laws must be somewhat more relaxed than EU & US regarding emission controls . . . Why not use a factory replacement part ? Just curious.

First this is not talk for these FORUM - if I know good ?....


Here peoples do not have 3700 EURO to replace particular filter on mini truck!
Maybe there have ?!
And for info new mini truck cost 15000 EUR , if you need to replace
particular filter you need to give 3700 EURO + SERVICE COST then where
is calculation ???
Mini truck is by GMC-ISUZU....... ;-)
RERGARD'S to you.

3700 euro is a big ticket item! People here do not have it either. What is the part you need ? Is there shipping restrictions to your country? Can you get it drop shipped to you from here or Japan? I cannot think of a part for a GMC ISUZU that is worth that much money. Is there a wrecking yard option? I understand about wanting to keep the criminal enterprise AKA government out from under your hood! The situation you face is why I prefer pre 1975 vehicles, no computers, no sensors, no Gestapo ordered smog checks.

Everything is ok my dear friend , I am not mad to nobody...

This thing's standing:
Truck have particular filter - Diesel Particular Filter ( DPF ) and there is
one sensor DPS diferencial pressure sensor wich give 1.00V DC on output
when filter is clean - OK.After some time maybe 2 year or little more time
dependent how you use truck self cleaning sequence of filter is dead!
Now you must replace filter becouse sensor give info tu ECU to pressure is
bad.....
Truck lose power to iddle !
If you remove filter you need to thel ECU to filter is still there ;-) haha
And truck will work fine with false data of sensor ( your false reference 1.00V).That is my full story with happyend becouse I success make false reference!
Regards to you and all.

Computer hackers, iPhone hackers...
Now we have truck hackers..... :eek:
That's funny :D

Glad it worked for you, FYI I checked FEDEX, a 1kg package valued at $100 US ships for $125 to $165 to Kosovo depending on what day it is shipped.

GM had the same problem in the 90s with their hot wire MAFS burnoff cycle, piece of junk always problems and then the car would run in open loop "limp mode" Terriable !
