This is a new one for me never heard of it the scanner said evap canister vent control valve open does anyone know what it could or the part number for this item?
I guess if I'm going to hijack, this is as good a time as any
So my car ran out of gas today @ half tank, forcing me to use that old faithful gas can in the trunk.
I have the p0455/p1448 code but I was told that these wouldn't cause our gas needles to read wrong. (Which makes sense)
Could it be the Fuel pump or sending unit? I saw in a thread that our cars fuel pumps and sending units don't usually go bad. When it did run out of gas, I heard a popping sound from under the hood. Almost like a leak.
The fuel pump can't cause the fuel gauge to read incorrectly. It is either the gauge itself or the sending unit.
the instrument cluster has a diagnostic built into it that will point all the instrument gauges to a certain spot. This will tell you if the gauge is good or not.
See page 122 in the 2002 EL section for diagnostic instructions. (Link below)
Step 7 of the procedure that points the needles is slow in moving the needles. It might take as long as a half minute.

I just adjusted my gas needle as 2kmaxim suggested in this thread https://maxima.org/forums/5th-genera...l-problem.html (post #33) My needle was a little lower than the fsm before my adjustment so we'll see if that fixes the problem, otherwise fuel sender unit it is.
I'll post results here
Okay, so I haven't seen the p0455 come back yet. (but it's only been one day, so i'll wait)
The gas issue.. after adjusting the needle, the gauge seemed to read properly for a moment. Then it rose right back up to over half tank, when I know it should be near or a little lower than 1/4 tank.
Here's a picture of the diagnostic after I adjusted the needle
Here's a picture of where the needle is now.. when it should be @ 1/4
Some car gauge pro screenshots, hopefully this helps?
(voltage ranged from 0.96 to 1.16)
I have never measured the voltage to the gauge, so I have no idea what the voltage should be. Do you know anyone in your area with a Maxima you could hook your gauge pro to and compare with.
But if the diagnostic positions the needle correctly, then I have to assume that the sending unit in the tank is bad.
