Check engine light on.

Misc. code P0441/P0455 evap emission

Dealer says they have to drop the gas tank to replace the fuel tank protector but they couldn't tell me what it does or how it sets off the check engine light.

Anyone else have this happen?

Maybe it releases gas pressure.

If you let your Tacoma sit Off for about 4 hours you will hear an electric pump sound for about 30 seconds. It does it all by itself, which scared me the first time it did it. I think it has something to do with pressure in the gas tank.
