BT-50 FLOWJOMETER FAILURE

I have a BT50 mazda with black smoke problems, valve rattle and lack of power and with admission air temperature sensor fault ??????? Can it be the flow or MAP?

If you put it that way, neither is the admission air temperature sensor only does that measures temperature is located in the air hose after filter or in the filter itself and has a two cable connector nothing more, the flow and the MAP fulfill another function and by definition it is not the same as you mention.

The strange thing is that the truck has a long start and not part, but if I push it ... it starts easy? And now it gives me a fuel code, I thought it could be a covered injector and that the fault has no relationship with the admission air temperature sensor code, but I would easily start if I had problems with injectors? (The spark plugs heat well)

Your truck is gasoline or diesel
and verify if the fuel filters are not clogged
verify in the diesel version that the bombin (where the fuel filter is going) is not damaged.
Check or verify the engine air filter, another item you can verify is the air flow sensor in the admission, it may be failing

where we work we have BT-50 diesel and the symptom you describe is due to injector damage (this is due to poor fuel quality) and fuel consumption is increased (verify your fuel consumption)

Thanks for the fact, I suspected the same and wanted to confirm it with someone who would have happened to him, I will make the injectors review and tell you.
