Good Call on there being a TSB:

TSB T-EG048-07 (M.I.L. "ON" DTC P043E, P043F, P2401, P2402, & P2419)
Models: ’07 Yaris Liftback

Some 2007 model year Yaris Liftback vehicles may exhibit M.I.L. “ON” with DTCs P043E, P043F, P2401, P2402, and P2419 stored. The fuel tank filler pipe cover holder has been improved to prevent water intrusion into the Key Off EVAP pump module.

1. Using TIS techstream, check for Diagnostic Trouble Codes (DTCs).
If DTCs P043E, P043F, P2401, P2402, and P2419 are ALL present, refer to the
Technical Information System (TIS), 2007 model year Yaris Repair Manual,
Engine/Hybrid System – Engine Control – “1NZ–FE Engine Control System: SFI
System: P043E: Evaporative Emission System Reference Orifice Clog Up”.

2. Replace the charcoal canister, charcoal canister filter, fuel tank filler pipe cover, and the fuel tank filler pipe cover holder if water IS or WAS present in the EVAP system.

3. Using TIS techstream, clear all DTCs.

4. Perform the Automatic EVAP System Check and verify that NO pending DTCs set.
