i have been reading up on the P0442 small evap leak code and P0456, but no one really has a solution for it. Anyone know? I have already bought a new gas cap, reset the ecu, and it went away for about 4 days then came back. I checked the hoses by the gas tank (by right rear wheel) what other hoses could i check? any suggestions on how to check them? I posted a while ago about the 02 sensor defouler and i havent gotten that code back (P0420.....knock on wood) but now I'm gettin those ****ty codes. I'm due for inspection this month so i need to get it fixed QUICK...thats the only thing wrong with my car damn it lol

 

I have the same codes man.

P0442 & P0455

I plan to "try" to take care of this sunday if I can...I think it might be attributing to my ****ty MPG

 

me too its weird its like when my fuel needle is at Full, it takes a while to go downto 3/4, but from 3/4 to 1/2, it goes down fast. not sure if it's normal or not but damn it seems like these codes aren't fixed very often. anyone know help us out lol

 

i know...i hate that you can't get a straight answer from most forums. because it is NOT always the gas cap. i don't know how many times i've tightened that damn thing and reset the code. I dont' want to waste 20 bucks ont eh cap either for it to come back.
