I put my new cluster in that I am working on and I have a check engine light. I hooked the scan gauge up to see what it was and it says there are 3 codes. One is P0442 and the other two I guess are P0000. Anyone have an idea on the P0000? P0442 says its a small leak in the EVAP system. What the hell does that mean? There is alot of lines to follow to find a leak. I guess the bulb for the check engine light in my truck now doesn't work so I wonder how long this has been going on.

 

Well I disconnected the battery for about a half-hour while I put the dash back together. I took the gas cap off and put it back on. Started the truck and no light so we will see what happens.

 

the light wont come back on instantly, may take a few hundred miles

 

Oh well, if it does I'll just put the bad bulb back in. With that code its not like its something I am gonna worry about. I'll probably replace the gas cap but that's as far as I am going with it.
