01 with P0442 evap code

[01thunder]

not much info on this code. small evap leak detected. anyone have this one and what was the solution? aside from checking the canister, which i wouldn't know how, i checked the hoses under the hood and did not see anything. gas cap is good. truck ran great yesterday. this morning, cel. i'm definitely not going to the dealer for this.

3 possibles:
evap line leakage
pump module failure-what is it?
canister faulty-i found where it is

I had the same problem and I kept resetting the computer. I replaced the fuel cap and it came back. The problem always came when my wife (hope she doesn't see this) was driving it. After I got her a new rav4 and started driving it myself (about a year and a half ago) it has never come back. The only thing I can figure is she was topping off the tank causing an overflow into the canister.
