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 the most common and simplest cause for a check engine warning.
• Look for other dashboard alerts or unusual sounds that might indicate a more serious issue.
• Note recent behavior: rough idle, reduced power, or fuel smell can signal ignition or catalytic problems.
• At Bill Estes Toyota in IN, our service team recommends a certified diagnostic as the next step — repairs covered by warranty must be performed at a certified dealership to preserve coverage.
