Frequently Asked Questions

What is the most common reason for check engine light on a 2013 Acura ZDX?

• Evaporative emissions leaks — a loose or damaged gas cap is the simplest and most frequent cause.
• Oxygen sensor or catalytic converter issues that affect emissions and fuel economy if left unaddressed.
• Ignition misfires from spark plugs or coils, which can lead to reduced power and higher exhaust temperatures.
• Minor causes are inexpensive to fix; delaying repairs often increases costs and risks damage to the catalytic converter.
• Our factory-trained technicians at Nalley Acura diagnose quickly and often deliver lower overall cost than independent shops, with warranty protection when applicable.

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

• It signals that the engine control unit (ECU) has detected a fault in emissions, ignition, fuel, or sensor systems.
• Codes can indicate anything from an evaporative leak to misfires or failed oxygen sensors — some are urgent, others informational.
• The light doesn’t always show severity; a quick professional diagnostic is the only reliable way to prioritize repairs.
• At Nalley Acura we use factory-grade scanners to capture freeze-frame data and trace the root cause, helping save money long term.
• Warranty-covered repairs must be performed at a certified dealership to remain valid.

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

• Inspect the gas cap for tightness and obvious damage — many codes clear after the cap is secured.
• Check oil and coolant levels for visible issues that could trigger warnings or run-condition changes.
• Look for obvious signs: unusual noises, loss of power, strong odors, or smoke; if present, stop driving and seek immediate service.
• If basic checks don’t resolve it, schedule a diagnostic with Nalley Acura for a thorough scan and expert repair plan.
• Remember: repairs covered under warranty should be completed at a certified dealership to protect your coverage.
