Misfuel risk Moderate
ES is gasoline or hybrid gasoline only in the US. Diesel nozzle mis-match is rare; contaminated or wrong-grade gasoline still requires tank draining before restart.
If the engine was not started
Keep ignition off; drain tank via access panel before priming.
If the engine was started
Replace fuel filter, inspect injectors and high-pressure pump (if equipped), and clear fuel-related DTCs per Techinfo.
Access procedure
- Relieve fuel pressure using Lexus/Toyota prescribed steps; disconnect battery negative.
- Remove rear seat cushion or trunk access panel to reach the fuel pump module cover.
- Disconnect wiring and fuel line quick-connects; plug openings to control vapors (OSHA 1910.106 precautions).
- Remove lock ring and extract pump/sender assembly per Lexus service manual.
- Drain contaminated fuel; inspect tank for debris or water intrusion.
- Install new seal, reassemble, and perform leak check before engine start.
- Clear fuel trim adaptations if required after extensive contamination repair.
Notes
- ES shares Camry platform components on several generations.
