I am having major EVP sensor problems. I've had to put silicone to seal the sensor because the gasket causes there to be "excessive EVP voltage". So i did that and then it was "< EVP voltage" so i tightened it up a little bit and now it does it under acceleration only instead of all the time. I went from .46 volts (after sealing with silicone) from the sensor up to .483 at Key On engine Off. By the way, i've also vacuum tested the valve with the new sealant, and it works great.
Here's my question, can anyone please measure their EVP voltage or look it up for me because I can't find any specs ANYWHERE. I've heard that it should be about .45 volts - ???. Can anyone verify this for me. I may end up increasing the voltage some more (maybe even up to .5 volt). I want to solve this problem because it's really, REALLY driving me crazy.
Thank you for listening,
