2008 accord with intermittent crank signal code

Hello everyone.

So the crank sensor has been replaced a few times even with the factory one (OEM). And has good power (5v) and good ground all under load. I dont remember the code number.

And this is what the signal looks like. Have any of you seen this before, because when i give gas the amplitude diminishes and the signal gets round instead of a good square waveform. 

I still think is a sensor issue, need same help. 

Thank you.  

fctnunes, I can see that a filter is applied to channel D in your capture:

 

Does turning the filter off change anything? Because, aside from the rounded edges, your signal seems to have the right frequency and amplitude. 

Are you getting P0335? When does the fault set?
