Good evening, I have a problem with a Fiat ulysses 2.0 jtd; sometimes not, and when only hot will turn off....diagnosis there are no errors, but it describes me, the customer appears in the monitor framework "code key "....
The thing makes me think immediately of the immo (the error with both keys), but the strange thing is that the off to hot what do you think ? and already happened to someone?
thanks in advance
monitors the engine if it sees them hot!!!
What is a hare? A rabbit Abarth
once that is in motion, the key code does not control it more, I would check the sensor.

Maybe the Ulysses....in a lot of it doesn't work.Originally Written by ugoboss
In any case, the fact that the signals from the immo does not, and the immo the sensor.
Hello. could you take a picture of the connectors of the ecu the motor disconnected??
If and what I think then I'll explain what it depends on.
It should be edc15c2 am curious about the problem that indicates mustanggt
of course mine may not be the solution as the result of an experience, like all of us, identical.
Most of the connectors : Renault, Fiat, VW, as we know, the connector on the ECU and a mascio.
That type of connectors used, the female, the inside have a layer of silicone that prevents the formation of imidità and corrosion.
In the long run, this silicone layer loses its effectiveness, it crystallizes and breaks down into small pieces.
Cold initially do not involve problems, but hot scalding mix with contacts and create defects that suggest the ecu went crazy.
THE problemea can only get worse in the end will not put in motion even more cold.
Of course, does not happen to all contacts but in some parts.
I initially proveriei with a flux dry, not too aggressive on the female connectors, if it holds up and warm it does not the connector must be disassembled to clean well.
This problem is solved on the renault clio II the first time, a point in the second and a pole in the third.
never returned with defects strange.
With regard to the control of the immo, I don't know the ulysses, but in many control and constant....now, I will not explain all the funzioamento and long and boring and very technical.
The renault, in particular, suffers from particularly.
In general, on the megane and clio II, and III occurs at 130-150.000 km.
Another defect of the absurd that made me lose the head just because I had no DTC.
The sensor of turns can not cause you to hot this problem, it would be a case really exceptional.
This, and that, according to experience that you may have.
I'm not a teacher MUSTANGGT, but I have many years of experience on his shoulders , and I can guarantee you that the speed sensors do just that defect, cold-work very well and when they heat up they stop to read and the machine stops and it is absolutely not a case exceptional, in any case, do as you want my recommendation.

we would not doubt it, and I commit myself to the experience.
in fact, I expressed for the symptoms in my.
now I would like to ragionassimo together, if it was the sensor of revolutions a bearing can be with the fact that you accennda the spy key code??
you have to understand how to work, and the sensor turns?!!??, what kind of sesnore and? the magnetoresistive? hall?.
in any case, you can control its state of operation with an oscilloscope, with the one not run!.
I repeat, I have expressed my opinion, based on experience, are here I also to learn and if someone explains to me what is the relevance of ec between the sensor and the key code I am shut up, and listen
That is the defect or not, the problem of the speed sensors, cold working, and heat damage problems are cases well known and established...in the old jtd was a defect in the order of the day. I agree with ugoboss about it.Let us know how it goes
