Frequently Asked Questions

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

• Check the gas cap first — a loose or damaged cap commonly triggers an emissions fault that illuminates the light.
• Confirm basic fluids and visible leaks; low oil or coolant can create warning conditions.
• Note recent symptoms: rough idle, reduced power, or unusual noises — these clues help technicians prioritize diagnostics.
• Even if a simple fix resolves the light, have Bill Estes Toyota scan codes to verify no pending issues; warranty-covered repairs must be done at a certified dealership.
• Using our dealership often costs less than independent shops over time due to accurate diagnosis, OEM parts, and reduced repeat repairs.
