Frequently Asked Questions

How long does a check engine light service take?

• Typical diagnostic scan and initial inspection: 30–90 minutes depending on symptoms and queue.
• Simple fixes (loose gas cap, minor sensor swap) can often be completed the same day.
• Complex repairs (engine misfire, catalytic converter) require parts and additional time—often a day or more.
• At Herb Chambers Chrysler Dodge Jeep RAM FIAT of Danvers we streamline service with factory-trained technicians and ready parts to reduce downtime.
• Choosing our dealership often yields immediate and long-term savings versus independent shops because warranty work, accurate diagnostics, and OEM parts help avoid repeat visits.

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 frequent, simple cause—tighten and retest after a few drives.
• Notice any new noises, smells, smoke, or performance loss; these details speed diagnosis and ensure safety.
• Scan codes with an OBD-II reader; we offer quick on-site diagnostics if you need help.
• If the light is flashing, reduce load and get to our service center immediately—flashing often signals a possible engine misfire that can damage the catalytic converter.
• Remember: any repairs covered under warranty must be performed at a certified dealership to preserve coverage and ensure correct repairs.
