P0 441 p0455
Hello these codes recently just kicked on my 07 rx 350 check engine and trac/vsc lights does anybody know or have any experience with these? I did some research and said could be just a gas cap or maybe an 02 sensor any ideas thanks for any help. I also recently got a new gas cap but I read the system could take up to 40 cycles to read this.

The check engine light does not always go off immediately after fixing the problem, you have to do the drive cycle thing as you read. But if you connect an OBD code reader, that can reset (turn off) the light.

Anyone else had this problem?
For a few months, the CELight comes on with OBD code for the EVAP Emission Control system P0456 ("very small leak"). Was ignoring it as only driving a few hundred miles per month.
Now it's become P0441 (incorrect purge flow) and P0455 (large leak).
I'll try replacing the gas cap with a new OEM one. I never overfill the gas.
Anything else I might as well buy to have handy while placing orders?
