I had those codes, new gas cap has fixed for now. No evap pressure

 

My 2001 is also throwing out a P0440 code. Gas cap replaced,and ECU reset and still P0440. I really dont want to mess with troubleshooting. Does anyone know how to bypass the system so the CEL doesn't come on and I can pass emissions? I know that sometimes resistors can be put in place of a sensor to trick the ecu. I would like to do something like this so I never have to worry about the evap system again.

 

Holy moly dude, creating your own thread would have been fine instead of posting in 10 other ones with the same question
