OBD Code Help

Bluesmoke91 · Jul 18, 2011

my check engine light came on and i OBD'd the truck and got this....

P0455- Evaporative Emission - System Leak Detected - (gross leak/no flow)

P0442 - Evaporative Emission - System Leak Detected - (small leak)

any idea what it could be? already checked the gas cap (didn't replace, just made sure it was locking).. Also, where is the charcoal canister located?

sometimes the gas cap can be bad even if it looks fine. could be time to buy a locking gas cap if you have been wanting one? they arent too expensive.

Yea I may be doing that but first id like to check any other preliminary things before spending money...im a college kid so every couple bucks hurts lol

The canister should be in front of gas tank connected to frame.. Big
Black box with hoses and what not
