What does it mean when the check engine light comes on in a 2022 Toyota Avalon Hybrid?

• The light signals that the vehicle’s onboard diagnostics have detected an emissions, engine, or hybrid system irregularity.
• Issues range from minor (evaporative system leaks, loose gas cap) to serious (engine misfire, catalytic converter or hybrid battery faults).
• Some codes indicate reduced fuel economy or emissions failures; ignoring them can raise repair costs and risk component damage.
• Immediate scanning identifies the code and recommended repair; our factory tools and technicians provide precise diagnostics tailored to the hybrid system.
