In 1 ocation it was ECU and I clearly remember that I had no codes of breakdown, but nevertheless the check's light was permanently on ... I hope it serves him. Safe.

Let's see if I understood, these cars the failure was that the ECU did not receive the sensor signal (or by short circuit or internal failure) and therefore presented this symptoms

Hello everyone, FloresGarcia, what I meant is approx 20 cars with that symptom, video, 19 were problems of the MAF sensor or connections or problems in the circuits, in 1 single occasion the symptom was due to the Ecu Mala. The symptom describes in the background that the ECU does not receive a signal, or this is incorrect or the ECU is not able to proceed it. Look in the case of Ecu Mala, the signal entered the ECU well, but it is for internal failure does not process it. The MAF signal is analog, therefore to be processed by the ECU, it must first be filtered (eliminates electronic noises), then the ECU digitizes it to process it, to be able to search in its internal cartographs (programming) the equivalence of that signal in grams per second of air ingraining the engine, which is the parameter that shows a scanner. In any of the previous cases the symptom is the same (video). On the accurate determination of this fault it can be done, but it is complex, therefore not to enrred it, Sujeri prove his ECU in another car, greetings

Excuse me, my fingers were faster than my understanding of your explanation. I will check wiring and connectors. I keep them upwards and thank you very much for your kind answers.
Greetings!

What such Meats, I continue with this detail, nothing else I find the fault.
I have been told that I also check the pressure regulator in the injector and empty rail, in the manual I do not find diagrams or how to check the empty. HELP.
Greetings!

greetings
