Hello everyone,i have a problem with my doblo 1.9jtd 74kw,2002 .
Yesterday,when i want to start engine,glow plug and check engine is start to showup(
before that, everything was ok, without errors)


I was conected OBD,and i have several errors:
-P1612
-P0236
-P0638
-P0101
-P0380
And also my speedometar is not working(yesterday when chek engine is showup,speedometar is stop working.)

Hello,
Don't worry for your english, it is really good ! I am not english but I have been able to understand you
First of all, that is a good choice. I never found a better car than a Fiat Doblo

Disclaimer : I am not a mechanic and whould not pretend to replace one. I simply uses my basic knowledge as maintenance technician and my own experience on fiat Doblo

For your issue, as far as I see, all errors code came from the motor ECU
P1612 -> issue with key identification
P0236 -> issue with pressure sensor
P0638 -> issue with gaz actuator (not sure for the right therm, sorry)
P0101 -> issue with air flow sensor
P0380 -> issue with pre-heat circuit
All this codes came from the ECU, you can check for plugs that can have been unplugged from it. You can also check if power go to the ECU (you can technically found electric diagrams on fiat website but warning : all colors are in italian !)

If you have issue locating the ECU I can propose you to check on EPER as it can help to find location for parts (but is not really accurate for olders vehicules)

I suggest you fit a new thick cable from clean metal on engine or gearbox to clean metal on the vehicle body .
