Check Engine Light Flashing

A flashing check engine light on your 2014 Hyundai Elantra Coupe signals a severe misfire or condition that can cause immediate engine damage. When the light flashes, unburned fuel is likely entering the exhaust stream and can overheat or damage the catalytic converter, leading to much larger repair costs if ignored. At Stevinson Hyundai in CO we treat flashing lights as urgent: our certified technicians perform a priority diagnostic, isolate misfire causes (ignition coils, spark plugs, fuel delivery, or sensor failures), and present clear repair options. Choosing our dealership means OEM parts, factory calibration, and warranty-backed repairs that protect long-term value. We also offer service financing so you can address urgent repairs immediately without delay. Check our current service specials for savings and schedule service online to get fast, trusted attention.

2014 Hyundai Elantra Coupe Check Engine Light Codes

Common check engine light codes for the 2014 Hyundai Elantra Coupe include P0420 (catalyst efficiency below threshold), P0300 (random/multiple cylinder misfire), P0130–P0167 (oxygen sensor circuits), and P0171/P0174 (fuel trim lean conditions). Each code points to different risks: untreated P0420 can mean costly catalytic converter damage; unresolved misfires (P0300) reduce fuel economy and risk engine wear; sensor circuit faults lead to poor drivability and emissions failures. At Stevinson Hyundai in CO our diagnostics clearly explain the cost-to-fix and long-term savings of timely repairs — fixing an oxygen sensor promptly can prevent far more expensive downstream repairs and restore MPG. Our team uses OEM replacement parts and calibrations to ensure reliability and preserve warranty coverage; if work is warranty-related, repairs must be done at a certified dealership, which we handle efficiently. To take advantage of our transparent estimates and factory-trained technicians, schedule service now and review available service specials.

2014 Hyundai Elantra Coupe Check Engine Light Reset

Resetting the check engine light on a 2014 Hyundai Elantra Coupe can be done with an OBD-II scanner, but resetting without addressing the root cause only masks problems and risks repeat failures. At Stevinson Hyundai we recommend a full diagnostic first — our certified technicians identify the trouble code, explain repair options, and reset the system only after repairs and verification. Dealer-performed resets paired with proper repairs maintain accurate emissions readiness monitors and protect your vehicle’s warranty and long-term performance. We use OEM parts and follow Hyundai service procedures for transparency, reliability, and documented service records. Our approach delivers immediate benefits (clear dash, restored drivability) and long-term savings by preventing recurrence and protecting components like the catalytic converter. Ask about service financing and current service specials to make timely maintenance affordable, and schedule appointment online to get started.
