Service fuel filter and inspect direct injection components per Toyota TIS.
Access procedure
- Relieve fuel system pressure per Toyota service information (fuel pump relay/fuse, crank briefly if directed).
- Disconnect the battery negative terminal.
- Access the in-tank fuel pump module via the OEM access opening (rear seat or trunk panel on most US models).
- Disconnect electrical connector and quick-connect fuel lines; cap lines to limit vapor release.
- Remove the pump lock ring with the specified tool; lift the module carefully to avoid damaging the level sender.
- Extract contaminated fuel with approved equipment; inspect the tank interior through the opening.
- Reinstall with a new pump O-ring/gasket; reconnect lines and verify no leaks before starting.
- Prime and clear codes per Toyota repair manual; road test when fuel quality is confirmed.
