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, low-cost cause and can trigger emissions codes.
• Look for obvious engine issues: smells, smoke, or unusual noises that indicate immediate danger.
• Note performance changes: rough idle, stalling, or reduced power help technicians prioritize diagnostics.

What is the most common reason for check engine light on a 2012 Toyota Venza?
