Po441 & PO455

I bought a 2008 Tacoma doublecab 4wd.It has a 6 inch lift on it.Drove it 4 hours from Houston to Louisiana no issues.Now have these two codes coming ug up PO441 & PO455.Any help with this is greatly appreciated.

 

P0441--Evaporative Emission Control System Incorrect Purge Flow
P0455--EVaporative Emission Control System Leak Detected (Gross Leak)

Basically (EVAP) is a system that contains the evaporation of gasoline vapors in your fuel system from escaping into the atmosphere. Get under the hood and look for a hose that has either cracked or fallen off from the canister or purge valve. Make sure to check your gas cap. You can throw an EVAP code if didn't tighten or replace your gas cap.

Those are good places to start. Since it is a gross leak, meaning a large leak in the system it shouldn't be too difficult to find.

If you can't locate the problem most good shops can do a smoke test and identify the problem. This test pumps smoke under pressure into the EVAP system. Because the smoke is pressurized it will escape from the open area indicating the locationof the leak.

Wish I could be more help.

 

The last time you filled up your tank, did you tighten the gas cap until you heard it clicking?

 

^^^^^^
Check this first. My (former) RAV4 had the same problem, which was solved with a new gas cap. The o-ring seal was worn by years of overtightening by the previous owner and wold no longer seal properly. $20 fix.

 

Thanks for the input will try all to fix this issue and the gas cap gasket does look worn.
