Check Engine Light Flashing

A flashing check engine light in a 2015 Ford Fiesta typically signals a serious misfire or fuel/ignition issue that can damage the catalytic converter if driven long distances. When you see a flashing light, reduce speed, avoid heavy acceleration, and bring the vehicle to Larry H. Miller Ford Lincoln Draper immediately. Our technicians prioritize flashing-light vehicles because rapid intervention prevents more costly repairs and preserves emissions equipment. At our Draper, UT service center, we use factory-grade diagnostic tools to capture live data, identify misfires, and test ignition coils, spark plugs, fuel delivery, and sensor inputs. We explain findings in plain language, present repair options that focus on safety and long-term reliability, and only install OEM parts to maintain performance and warranty coverage. We also offer service financing so you can address urgent repairs now and pay over time. Check our current service specials for added value. To protect your vehicle and avoid cascading damage, schedule service online or call our service team for immediate assistance.

2015 Ford Fiesta Check Engine Light Reset

Resetting the check engine light on a 2015 Ford Fiesta might clear the dashboard temporarily, but it does not fix the underlying cause. At Larry H.

Our certified technicians use OEM scan tools to read and interpret stored codes, advise whether a reset is appropriate, and perform repairs using Ford-approved parts and procedures. This transparency ensures warranty compliance and long-term vehicle integrity. We also provide written estimates, estimate timelines, and outline how the repair preserves fuel economy and component life. If a reset is part of routine maintenance after an approved repair, we perform it and monitor live data to verify that the fault does not return. Take advantage of our service financing and seasonal service specials to manage costs. To prioritize your Fiesta’s reliability, schedule appointment today—our team in Draper, UT will keep you informed at every step.

2015 Ford Fiesta Check Engine Light Codes

Common check engine light codes for the 2015 Ford Fiesta include P0420 (catalyst efficiency below threshold), P0300 series (random/multiple misfires), P0171/P0174 (fuel trim lean), and various oxygen sensor or EVAP system trouble codes. Ignoring these codes can lead to escalating costs: untreated misfires can damage the catalytic converter (costly to replace), persistent lean conditions reduce fuel economy and acceleration, and unresolved EVAP faults can trigger failed emissions tests or poor drivability. At Larry H. Miller Ford Lincoln Draper in Draper, UT, our factory-trained technicians interpret each code, prioritize repairs that protect your wallet and vehicle lifespan, and use OEM parts to ensure proper fit and performance. We also explain the immediate cost-benefit—addressing codes early often costs a fraction of the price of major component failure—and provide options like service financing to spread payments.
