Cleared P0449 now seeing P0446

[FireDawg212]

Last weekend I replaced the evap solenoid & tube assembly and the CEL cleared for a little over 24 hours. I stopped by the parts house and the code that has popped up now is P0446. It seems that these are similar parts from what I've read? I need to know what to do to clear this out completely!

Please help me out with this!

Can anyone help? I am also seeing the fuel fill issues I've read about other places but I thought that was associated with 0449 code?

I had to replace all 3 part before the code would go away. Once I replace the valve on the intake the code cleared its self.

Thanks for the replies. I have the part on the intake coming in tomorrow. I actually happened upon that thread yesterday. Hopefully we'll it fixed for good tomorrow.

Thanks again!
