2004 Nissan Sentra emissions leak

What is the problem you are having?

I am just trying to understand the problem with my car and the solution that was done to my car, 200.00 dollars later. A dump valve was put on a charcoal basket. I guess it needed replacing. Engine soon light came back on, I took it back to the guy that is dealing with it for me. Now I'm told not the right gas cap. Apparently clicking this one 3 times is not offering enough weight to not make it leak? Does any of this sound remotely correct to you?

First, what is the code number? If it is a reputable shop then it should be on your receipt or the advisor told you.

I was not given a code. And I am not doubting the guy. He is pretty good. I am just trying to understand what he is doing. I had a hose replace this past year that had to do with my gas tank. He also informed me today that the return line is also new , because I asked if there could be a crack in the return line. He wants me to try another cap. He said what is happening is that each time something is done, a different number shows up, and they are going to try the cap to see if that works to keep the light off. If it doesnt , they are going to do"smoke thru the car" to see where it comes out so they can find the possible hole , if one. Does any of this make sense? They told me some of these cars are sensitive to emissions leaks. Even a pin hole. By the way, Thank you for responding.

If you have the code(s) then I could explain to you what is going on and what he is probably testing. I can explain to you how the EVAP system works, but w/o the code then I can't tell you what he is testing and why.
