Frequently Asked Questions

What is the most common reason for check engine light on a 2010 Acura RDX?

• Loose or damaged gas cap causing an EVAP leak code (often the easiest fix).
• Faulty oxygen (O2) sensor or mass air flow sensor creating emissions and fuel-trim codes.
• Engine misfires from worn spark plugs or ignition coils, which can cause catalytic damage if not addressed.
• Evaporative system leaks (P044x codes) and catalytic converter efficiency codes (P0420) are common as the vehicle ages.
• Our technicians diagnose quickly and explain the immediate repair needs and long‑term cost implications.

What does it mean when the check engine light comes on in a 2010 Acura RDX?

• A steady light usually signals a stored fault that needs diagnosis; it can range from minor to serious.
• A flashing light indicates an active misfire or severe condition—stop driving and seek immediate service.
• Codes are stored in the vehicle computer; scanning reveals causes like emissions, ignition, or sensor failures.
• Prompt diagnosis prevents bigger failures and higher repair costs; warranty-covered repairs must be done at a certified dealership.

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