I'm getting this CEL:

P0453 Evaporative Emission Control System Pressure Sensor High Input

Car seems to be running perfectly fine, but this CEL came on, and has come back a couple times after clearing it. My only thought is that maybe it's the fuel pump b/c I have a Walboro on there, although the rest of my car is now NA (used to be supercharged, but the fuel pump was left in by the guy I bought it from). Then again, I'm not sure the fuel pump would cause this CEL though. I've never done a fuel pump swap myself, but from what I understand it can be a pain, which isn't worth it if it's not causing me any problems.

Any idea of what might be causing it?

Aww, c'mon, don't tell me I've stumped all of UTH!

get a shop manual and start diagnosing... theres probobly a sensor on like the emmissions canister maybe?? that ahs gone bad.... i dont see how your fuel pump would have anything to do with an evap pressure sensor? unless that sensor is intigrated with the fuel pump module??? could be i dont know too much about that sensor myself...

Has anyone dealt with this code?

i have not delt with this code, how ever i know that on some cars if you dont tighten the gas cap all the way that it will throw a evap code and a check light... on my 02 the gas cap clicks like its tight but it really isnt and you have to keep going ( sounds stupid i know ) but try that...
