Frequently Asked Questions

What is the most common reason for check engine light on a 2013 Acura TSX Sport Wagon?

• Most often it’s a loose or faulty gas cap that triggers an EVAP system code—an inexpensive fix that clears the lamp once addressed.
• Other frequent causes include oxygen sensor wear, EVAP leaks, and occasional misfires from ignition or fuel issues.
• If left unaddressed, small items can escalate into catalytic converter damage or poor fuel economy.
• At Nalley Acura we diagnose with factory Acura tools to pinpoint the cause and avoid unnecessary repairs.

What does it mean when the check engine light comes on in a 2013 Acura TSX Sport Wagon?

• It signals that the engine management or emissions system detected a fault; severity ranges from minor (loose cap) to serious (misfire).
• A steady light usually indicates a non‑urgent emissions or sensor issue; a flashing light often signals active misfires that can harm the catalytic converter.
• Proper diagnosis requires a factory-grade scan to read stored trouble codes and freeze-frame data.
• Our factory-trained technicians at Nalley Acura use OEM procedures to determine next steps and protect long-term vehicle health.

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

• Start by checking the gas cap—tighten it until it clicks and drive a short distance; many EVAP codes clear quickly.
• Look for performance changes, smells, smoke, or drivability problems; note any symptoms for the technician.
• If the light flashes or the vehicle runs poorly, stop driving and have it inspected to avoid further damage.
• For warranty protection and accurate diagnostics, bring the vehicle to Nalley Acura so any covered repairs are performed by a certified dealership.
