Error Code: PO453 - Toyota Yaris Forums

Its most likely a bad fuel tank pressure sensor. I believe its a 2 wire sensor thats located somewhere on top of the gas tank thats pressed in. Never changed one on a yaris but typically thats the most common for that code. That or a stuck closed canister purge valve.

The Yaris doesn't have a fuel tank pressure sensor and the OP's JDM Vitz lacks a canister purge valve, like USDM Yaris have.
