Po455, Po446, Po441

[tfitzgerald]

Hi guys,

I have the following codes PO455, PO446, PO441 that are coming up with my code scanner on my 2004 Toyota Camry 4 cylinder. I have searched TN and the net and I have only seen responses with PO446 and PO441. Can someone tell me what the three codes combined means? I hoping that since there are three, the problem will be easily isolated.. I know this never happens, but one can wish!

Thanks in advance.

I found these on another Toyota forum. Don't know if they are of any help. Good Luck.

P0441 Evaporative Emission Control System Incorrect Purge Flow
P0446 Evaporative Emission Control System Vent Control Circuit
P0455 Evaporative Emission Control System Leak Detected (gross leak/no flow)

Those are emissions related codes. Most likely you didn't tighten your gas cap. I would fill up again, make sure the cap it turned until it clicks and stop by a autoparts store and have them clear the code (or you could pull the EFI fuse for 10 seconds
