2014 Acura TL Check Engine Light Reset

Resetting the check engine light on a 2014 Acura TL is straightforward when the underlying issue has been diagnosed and repaired, but a simple reset without repair only hides the symptom.

Warranty repairs must be completed at a certified dealership to remain valid.

2014 Acura TL Check Engine Light Flashing

A flashing check engine light on a 2014 Acura TL signals an active misfire or other condition that can cause catalytic converter damage and engine harm if driven. Flashing is a higher priority than a steady light and requires immediate attention — continuing to drive may lead to costly repairs. Nalley Acura recommends bringing the vehicle in right away; our factory-trained technicians perform a thorough diagnostic, road test, and targeted repairs. Addressing a flashing light promptly saves money by preventing escalation, preserves emissions components, and protects warranty coverage, which requires certified-dealership repairs. Contact our service team in GA for fast assessment and clear cost estimates tailored to your vehicle’s needs.

2014 Acura TL Check Engine Light Codes

Common check engine codes for a 2014 Acura TL include misfire codes (P0300–P0306), oxygen sensor faults (P0130–P0167), catalytic efficiency codes (P0420), MAF or air metering issues (P0100–P0104), and EVAP system leaks (P0440). Left unresolved, these issues cause poor fuel economy, increased emissions, and progressive component failure—what might start as a sensor replacement can escalate to needing catalytic converter or engine repairs that cost substantially more. Nalley Acura’s diagnostic process identifies codes quickly and provides cost-effective repair plans. Our dealership often costs less than independent shops when you factor in accurate diagnosis, OEM parts, and long-term savings. Warranty-covered repairs must be completed at a certified dealership to maintain protection and ensure correct repairs.
