What does it mean when the check engine light comes on in a 2025 Honda Accord?

• The light signals that the vehicle’s onboard diagnostics detected a fault in engine, emissions, or related systems.
• Common causes include a loose gas cap, oxygen sensor issues, EVAP leaks, misfires, or emissions-control problems.
• Severity ranges from benign (tighten the gas cap) to urgent (misfires that can damage the catalytic converter).
• Our dealership uses OEM diagnostic tools to read codes, interpret freeze-frame data, and recommend the correct repair path.
• Warranty-covered repairs must be performed at a certified dealership to maintain protection and service history.

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

• Start with the simplest items: ensure the gas cap is fully tightened and inspect the fuel door area for obvious issues.
• Check for other dashboard warnings, reduced power, rough idle, or unusual noises—those details help pinpoint the problem.
• If the vehicle runs normally after tightening the cap, the light may clear after a few drive cycles; if not, bring it in for diagnosis.
• If the light is flashing or you notice severe performance loss, stop driving and have the vehicle towed to the dealership to avoid further damage.
• Repairs covered under warranty must be performed at a certified dealership to keep coverage valid and documented.

What is the most common reason for check engine light on a 2025 Honda Accord?

• A loose or damaged gas cap remains one of the most frequent and simplest causes—often the quickest fix.
• Other common reasons include oxygen sensor failures, EVAP system leaks, and ignition misfires caused by coils or spark plugs.
• Ignoring recurring codes can lead to larger failures like catalytic converter damage, which greatly increases repair cost.
• At Courtesy Palm Harbor Honda, our factory-trained technicians diagnose the root cause to prevent repeated issues and lower long-term repair expense.
• Warranty repairs must be carried out at a certified dealership to preserve benefits and ensure OEM-quality parts and labor.

How long does a check engine light service take?

• Simple repairs—like replacing a gas cap, oxygen sensor, or clearing codes after a confirmed fix—can be completed the same day in many cases.
• More involved repairs, such as ignition or catalytic system work, vary from a few hours to a day depending on parts and labor.
• Courtesy Palm Harbor Honda often completes work faster than independent shops thanks to parts availability and factory-trained teams, delivering both immediate and long-term savings.
