Had code 446. Replaced part with 214-2149 reset codes and everything was fine for two days. the check engine light is on again. Any suggestions? Thanks in advance for the help.

Welcome to

I'm sure some of the guys will chime in and try to give you a hand but it might be a bit more productive if you introduce yourself as well.


When did the problem begin and when was the last time you got gas? Sometimes you'll get evap codes if you don't have the cap on all the way or if the seal is bad. It's an easy place to start in any case.

Leaks in the lines/hoses will also launch this code.
