PO441 and 455 Codes in my 06..Anyone ever had these codes before?

I just got these codes on my 06 Tacoma V6 and it runs the same as usual but I can tell the fuel mileage is suffering.I believe these codes are dealing with the Evaporative canisteris bad or has a leak somewhere.Was just wondering if any of you all have had this code / problem before and what fixed it.Thanks everyone!

Seems like you did some homework. You gotta do some or have someone do se diagnostics for you with a smoke machine. You can isolate either end of the evap system with a scan tool and run vac/smoke tests to find out what solenoid is out or other leaks are around.

 

Here is the OBDII code list. And some Evap system info. 9 times out of ten, you got the code because your fuel cap wasn't tightened all the way. Also be careful of trying to get the "perfect pump" and over filling. Although the baffle isn't supposed to allow fuel into the evap system, it can happen. When the pump shuts off, you're done.

When I had my 06 I had those codes it was a bad gas cap. Bought another Gas cap from dealer happened again. I bought one from Autozone and it never happened again.

 

Put some grease on the gas cap gasket and retighten and then disconnect battery for a couple of minutes. The check engine light should go away. If not replace gas cap.
I have done this with mine, another friends tacoma, and another fj.
