Open the hood, look at the airbox, on the left hand side there is an electronic valve with two hoses connected to it but I bet that the rear hose of the two has pulled off. Reconnect it and disconnect the battery for 10 minutes to reset the codes. HI. That was exactly the case for my echo 2003. 5 days after changing air filter at canadian tire...check engine appeared. I get the codes p0441. p0442 and p0446. As mentioned at the above comment, the rear hose was disconnected. just reconnected it erase codes and all is fine. thanks a lot for the suggestion.
