Common causes include oxygen sensor fault, EVAP system leaks, ignition coil or spark plug issues, and occasionally catalytic converter deterioration.

Start with simple checks: confirm the gas cap is properly tightened and look for obvious performance symptoms (stalling, rough idle, or loss of power). Many times a secure cap or a quick fluid check can resolve a stored code. If the check engine light is flashing, avoid driving the vehicle—flashing typically signals an active misfire that can damage the catalytic converter. In that case, contact us immediately and schedule service. Our team will run a full OEM-level scan, explain results in plain language, and present repair options and costs. Financing options and current service specials can make immediate repairs affordable.
