Frequently Asked Questions

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

• Check for obvious issues first: loose or missing gas cap, unusual noises, or visible leaks — simple fixes can clear the light.
• Verify dashboard messages or reduced-power notifications; the vehicle may restrict performance for protection.
• Do a quick scan with an OBD-II reader if available, but avoid clearing codes without repair — that masks problems.
