Frequently Asked Questions

What is the most common reason for check engine light on a 2011 Acura TSX?

• Loose or damaged gas cap is often the simplest cause — it triggers the evaporative emissions system and an easy fix.
• Faulty oxygen sensors, mass airflow sensors, or ignition misfires are common and can affect fuel economy and emissions if left unattended.
• Failing catalytic converters or EVAP leaks cause progressive damage and higher repair costs over time.
• Addressing issues early with Nalley Acura usually costs less than independent shops while delivering factory-trained service and genuine parts.
• Remember: warranty-covered repairs must be done at a certified dealership to preserve coverage.

What does it mean when the check engine light comes on in a 2011 Acura TSX?

• It signals the vehicle’s onboard diagnostics detected a condition outside normal parameters — anything from loose gas cap to engine misfire.
• A steady light typically indicates a non-emergency issue; flashing often means active misfire risking catalytic converter damage.
• Diagnostics identify the specific trouble code so technicians can recommend targeted repairs and cost-effective solutions.
• Our dealership offers precise diagnostics and factory-trained technicians who prioritize immediate fixes that lower long-term ownership costs.

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

• Start with the gas cap: confirm it’s tight and undamaged, then retighten and see if the light resets after a short drive.
• Check basic visible items — low oil, coolant levels, or obvious wiring and vacuum leaks — before driving long distances.
• If the light persists or is flashing, stop driving and bring the vehicle to Nalley Acura for an immediate inspection to prevent further damage.
• Certified diagnostics and repairs at our dealership protect warranty coverage and often save money over independent repair attempts.
