Need help with trouble codes

My check engine light came on today. I checked to see if there were any codes with my power programer. It came back with three. #1 is P0000, #2 is P0455, and #3 is B3004. Can anybody help me with the definition if these codes.

Thanks:

The only one of those I have on my list is...
P0455 ‐ Evap Purge System Large Leak

I don't show the other two, however
I have read out my codes and seen the P0000,
it did not trigger an engine light so I have reset it
without any issue.

P0000 usually means end of DTCs or No DTCs found

Hey Chromedome , How are things. What was the large leak in you evap . We got alot of snow, I think that I ran over some large chunks of ice. My jeep was telling me that my gas cap was bad, then the check engine light came on. Hope I didnt screw anything up. I will get under there and check things out tomorrow.

Thanks:

If it helps at all, I had never seen "3" as te second character (usually 0 or 1) in the code so I did a little research


With Body codes, "2" is reserved for OEM use and "3" is reserved for SAE assignment.


"0" as the third character is SAE reserved for future use, lol

Basically, that is a F'ed up code to try and decifer.


P0455

p=Powertrain, 0=Generic, 4=Auxiliary Emission Controls, 55=indicates Evap system. So this can mean loose gas cap, Evap canister or other leak in the emesions system

I am guessing that (Body code) combined with the other codes is indicating the Evap canister is broken
