Frequently Asked Questions

What is the first thing to check when the check engine light comes on?

• Check the gas cap: a loose or damaged cap is a common, simple cause and can trigger an emissions code.
• Look for obvious issues: signs of low oil, overheating, or a dramatic drop in performance warrant immediate attention.
• Note symptoms: intermittent stalling, rough idle, or loss of power help technicians pinpoint problems faster.
• If the light is flashing or the vehicle is running poorly, stop driving and have Bill Estes Toyota evaluate it to avoid larger repairs.
• Remember: repairs covered under warranty must be performed at a certified dealership to preserve coverage and long-term savings.
