When the check engine light turns on, it’s your vehicle’s way of telling you something needs attention. Sometimes it’s minor, like a loose gas cap. Other times it can point to an issue that affects performance, fuel economy, emissions, or long-term reliability. Piney Green Tire Pros provides check engine light diagnostics in Jacksonville, NC to identify the cause quickly and help you make the right next decision.

Our technicians perform engine diagnostic testing using professional scan tools to read trouble codes and review system data. From there, we confirm the real issue through targeted testing, because a code is a starting point, not a final answer. Many problems can trigger the same warning, so accurate diagnostics matter.

Common causes of a check engine light include ignition and fuel issues, failing sensors, airflow concerns, emissions system problems, misfires, vacuum leaks, and EVAP system faults. You may also notice rough idling, hesitation, reduced power, unusual smells, or decreased gas mileage. If the light is flashing, it usually indicates a more urgent misfire condition that should be checked as soon as possible.
