Good evening all, I have my hands on a alfa 147 1.9 jtd 150cv year 2006 strattona and it does not take speed in diagnosis I have the' error p0203 injector circuit 3 open.
At a minimum, the machine runs well when you requires you gas it rips and doesn't take the turns I tried to detach and reattach the plug but it all seems ok could it be the wiring ? there is already happened to you ?
thanks in advance
As fix as we put in the diagnosis?Originally Written by Supercharger
Unlikely to be the wiring maybe the plug and happened..
Check if they have opened the ECU and not sealed as god commands, and possible presence of water inside..
Otherwise because of the simplicity of the assembly and portals from the pompista of confidence will be the coil of the injector..

thanks a lot then:
correction cyl 1 -0,60 mm3/inj
correction cyl 2 -0.26 mm3/inj
correction cyl 3 0.00 mm3/inj
fix cyl 4 0.79 mm3/inj
check the ecu and then if it doesn't I revise the injector
thanks again as soon as I fix it I'll know
a polo 1.2 petrol has made me this defect, but it was not a 4-perfect, it was lame, swapped the injectors, but there was always the 3 that didn't.
connectors are perfect, to the control signal, however, was unstable, continuity, however, was ok.....sprayed just flux, re-start, deleted the DTC the engine, never seen.....
the fact that the contacts are ok there and the said ce signal arrives perfect, just a little.....a splash of flux will not hurt the ago.
Before bringing them to revise invert the "defective" with another cylinder and see if the fault moves..
Marked 1-2-3-4 otherwise you have to recode the codes ima..

Hello in the workshop it happened to me 3 times on the 150-hp always on the third injector connector new, and always worked after! Good day to all
but I what I write to do!......what are grandfather that shoots c....you!....what I just wrote!.....
the fact that it happened on a polo shirt instead of on the alpha always of the connectors it is!......
have you discovered the hot water!......
maybe so, and more clear of what you wrote savior
......the usual story....you mechanics know everything....now you are programmatri, cyber,biochemical, pompisti and engineers because you learn from an image to connect 1 programmer and press three buttons.
then I know what they are, a mechanic, because I am done distribuziona alone therefore from now I can do the work to customers and snub the suggestions by repeating them in a parrot?....
The reference and purely direct......
give up.
check faston third cylinder which is not labile,
thanks to all problem solved...I went from total collapse, I took a plug already wired cut and soldered the wires, and the machine goes that is a viola....after having observed it carefully, you could see the socket burnt to the interior thanks again to all
