camshaft sensor failure

[Fly17]

The engine was vibrating when running from the exhaust pipe was white smoke. After starting the engine vibrate, the message EECU fail. The reason - the camshaft sensor failure (defined Wizard program)

I have had that sensor light up the ECU A FAIL light a few times, but only in flight. Apparently the sensor is not *read* in flight, only during the startup, so if you get it at a different time it is a false reading and can just be reset.

He works in flight, too, because it gives information on the situation EESU valve for more precise fuel injection. By the way two of them, I have two at once, because determine what happened. A change at a time and look for faulty does not always work, besides, he could again make it an electrician and she is not prognose.In our flight includes the fuel pump itself an additional tank, but the tank was empty. In inforrmatsionnom window PFD aux pump on. Prilitaem everything is working properly. After analyzing the electric schem decided to replace the fuel pump relay, because of all the units it has a low reliability, and as a result more of this will not be repeated.

It appears your engine had a momentary camshaft sensor failure that lasted only one second.

The green event that you circled showed the sensor function restored, but the red event a few lines below that showed the earlier failure. The time stamps of these two events are only 1 second apart. I'm surprised that was enough time to make the engine vibrate abnormally and generate white smoke.

I agree with you. I chose a bad example. It was during one second is turned on again after the engine stop. When starting the engine error burned over time it was clearly visible. When removing the sensor housing crack was detected visually. After all the correct output, loading screens screen. In addition to the recent refusal of the left engine always run worse than the right. The temperature was above 20 degrees Celsius

I give the arguments to your comment
