So i hear so loud rattling/ vibrating under my truck at it turns out i have a quarter size hole in my muffler. So with that figgerd out i went to my next problem witch is with the EVAP system. Im geting the code P0441. I checked all the hoses and they are nice and tight and look new. So my question is what else can be giving me this code and is it safe to drive with this because i dont want anything else to go wrong.

 

check replace your gas cap

 

Did that and its still on

 

Just threw the same code, checked the gas cap and nothing. Did you have find out any information?

 

yeah i replaced my gas cap and it went away it took about 30-45 mins of driving for it to go away tho

 

Go copy the EVAP system map I have in the FAQ section and start tracing lines. Look real hard at hose ends and clamps, especially around the canister...

 

gas caps are prone to failure. throwing codes and also failing inspections. some areas will actually pressure check caps during emission inspections.

any one else seaching this thread: its an easy cheap remedy to exhaust / evap issues when you get stumped with all diagnostic checks.
