FIAT Doblò 1600 16v

[Tinturia]

Good morning.
I have found in a Fiat Dobl? 1600 16v with lpg system, the following error codes:

u1602 error CAN line
p0571 cruise control
p0460 sensor ****llo fuel
u1600 electronic key
p1687 motorised butterfly (stop learning)
p0171 system lean critical

What do you think ? the problem? I think there is to change the ecu.
The car has an ecu MArelli IAW 5nf hw103. If I wanted to try to mount a Marelli 5nf hw102 would be compatible?

[Tinturia]

As to the accuracy of the control unit mounted on the car Marelli IAW 5nf T2, the other ? a Marelli IAW 5nf T1 that was mounted on a Stilo 1600 16V.

plant and stock or mounted after

mounted after

you can try to put the file ori on what changed then the t1, it becomes t2 if you need I can do

I'm glad you can do it but I don't think you're the only one on this forum to know how to clone a unit...I wanted a hand to understand if the two hw are compatible (I don't want to take a control unit which then I can use), and if the error codes are derived from the unit is not working or some other fault.

[redline]

be to check the error codes from what arise depends only and exclusively with the professionalism that each of us has

p0171 ? induced by the ill-fuel mixture gas (with little knowledge of how to adjust the gas or little desire, generally the sum of the two)
p0460 I assume that this is triggered by wrong sensor ****llo is installed on the ****llo fuel benza which serves to avoid that the needle drops when you go to the gas
p0571 may be induced by an ill-adjustment of the gas

the other may simply be a failure to verify.

the transmission ecu does not solve your problems unless you are real, and I don't think they are.

[Tinturia]

You are rightly free to believe us? that you want. I have only transcribed the errors seen in the diagnosis. This machine is sometimes not part, if the part turns off after a little or not salt is good laps. I knew that in these engines, the throttle body sometimes does not work well, and it happens that the units will fail (information give me a plumber, gas plants). I put the post why? maybe to someone ? gi? happened something similar and could give me some right direction.

u1600 electronic key there is' always in the fiat, u1602 error CAN line ? the relative de l first , p0171 system lean critical due to gas certainly, I don't think is to replace the ecu but the failures are cancellabbili you still have the machine

[jolidj]

if you turn off, or if nn takes l-accelerator or error in the can , no if you delete from the diagnosis to the ecu, and repair.
you can mount the-other ecu , and the same thing, decide to make a scodifica but the eeprom in the ecu and to the internal and nn if you have a tool that reads the eeprom without open then do the scodifica , if no ricodifichi the keys and gone with the wind.

[Tinturia]

The errors in the ecu clears but as soon as power back up, the car rolls a little and repeat. Gi? at a minimum goes wrong, there seems to be the drawn air, c'? an excess of air with respect to the fuel (both petrol and gas) so I think that there is the throttle body that doesn't work well. The instruments for making the scodifica I have it... I try and I'll know. Thanks for the constructive feedback made, to help and not to criticize or question the professionalism? or another.

if I understand it, the car part bad in my opinion first of all would check the injectors in short, I think there is something that goes in the loss of gas, try to disconnect the gas pipe that feeds the injectors test the day after to put in motion the day after and hear how it goes:)

[Tinturia]

Hello all, after several tests, verifications, etc., solved the problems by changing the ecu, throttle body, and review with the injection system. The machine ? around 15 days and has no problem.

but the gpl and of the series or ? installed after if ? was installed by a plumber, let us mount a variable valve timing electronic and foul place to 12 degrees to the gpl, and when it goes abenzina returns automatically to its place and have it fitted with spark plugs more cold as wr7dc , mountains wr6dc with a small gap of 200 microns.
