Frequently Asked Questions

What is the most common reason for check engine light on a 2024 Toyota Sequoia?

• Common causes include ignition misfires, oxygen sensor failures, catalytic converter efficiency faults, and EVAP system leaks.
• Misfires and bad O2 sensors are frequent and can reduce fuel economy and increase emissions.
• If left unaddressed, minor issues can lead to catalytic damage or more expensive engine repairs.
• Prompt diagnosis at Coggin Toyota at the Avenues prevents collateral damage and preserves warranty protection.

What does it mean when the check engine light comes on in a 2024 Toyota Sequoia?

• It signals that the vehicle’s onboard diagnostics (OBD-II) has detected a fault in engine, transmission, or emissions systems.
• The light can indicate anything from a loose gas cap to a serious misfire or emission control failure.
• Note whether the light is steady or flashing—flashing usually indicates a more urgent issue.
• Bring your Sequoia to our certified technicians for a full scan to identify the exact code and recommended repair.

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

• Start with simple checks: ensure the gas cap is tight and inspect for obvious issues like low fluids or visible leaks.
• If the light persists after those checks, perform a diagnostic scan to read stored trouble codes.
• A quick dealership inspection will confirm if driving is safe or if towing is recommended to prevent damage.
• For any warranty-related repairs, remember they must be performed at a certified dealership to remain valid.
