Codes P043E and P2401

[Edp2009]

I just got these codes this morning. I've been having problems with my emission system lately and I've already changed the air injection valves and pump. This is the first time I've gotten these codes and everything I'm reading online says I need to replace the vapor canister or charcoal canister. Has anyone else ran into this problem?

looks like the A/F sensor and charcoal canister, you can always try replacing the A/F sensor first which is the less costly and clear the Check engine codes and then see if you still get the P043E code if so then the charcoal canister will need to be replaced too. if you go the A/F sensor route be sure to get a DENSO/NGK brand replacement other brands will not function properly>http://www.rockauto.com/ http://www.customtacos.com/tech.old...6toyrm/06toypdf/06rmsrc/rm2006ta/01200710.pdf

Late to the party, I get the same codes, I was told it was from over filling the gas tank.
It come back every now and then (6 months from the last time) but the lucas gas treatment clears the code.

Gas treatment wouldn’t clear an over fill code. You got something else going on and the treatment is masking it.
I’m not enough of a pro to troubleshoot it further, but I’m sure of that.
