What is the most common reason for check engine light on a 2014 Ford Mustang?

  • Common causes include loose gas caps, failing oxygen sensors, ignition misfires, and EVAP leaks. Each has a different risk profile and cost if left unaddressed.
  • Left unchecked, a simple sensor issue can reduce fuel economy and lead to catalytic converter damage, which is significantly more expensive to repair.
  • Our factory-trained technicians diagnose the root cause quickly, using OEM parts to restore performance and maximize the life of your Mustang.
  • We recommend prompt service; you can schedule appointment or check service specials to save on immediate repairs.

What is the first thing to check when the check engine light comes on?

  • Start with safety: if the light is flashing, stop driving and have the vehicle inspected immediately (see more below).
  • For non-flashing lights, check the fuel cap for a proper seal; a loose cap is a common and inexpensive fix.
  • If the light remains on, bring your 2014 Ford Mustang to Larry H. Miller Ford Lincoln Draper for a professional scan and diagnosis; dealership repairs often provide better immediate and long-term value.
  • You can schedule service online, take advantage of our service specials, and learn about finance options for larger repairs.

Check Engine Light Flashing

The check engine light flashing is a warning that your 2014 Ford Mustang is experiencing an active misfire or another severe engine condition that can rapidly damage the catalytic converter and other components. A flashing light often means combustion is occurring outside normal timing, increasing temperatures and unburned fuel that can destroy emission control systems within miles. At Larry H. Miller Ford Lincoln Draper in Draper, UT we treat any flashing light as an immediate-priority issue: our service advisors will help determine whether you should stop driving, whether towing is recommended, and provide a clear estimate for repairs. Using factory-grade diagnostics and OEM replacement parts, our certified technicians isolate misfires, ignition coil or plug failures, fuel injector problems, and wiring issues to avoid compounding damage. We also maintain clear communication on cost, timing, and warranty implications; remember that warranty-covered work must be performed at a certified dealership to remain valid. Check our current service specials and schedule service immediately to protect your Mustang and prevent costly downstream repairs.

2014 Ford Mustang Check Engine Light Codes

Common diagnostic trouble codes for the 2014 Ford Mustang include P0300 (random/multiple misfires), P0171 (system too lean), P0420 (catalyst system efficiency below threshold), and P0456 (EVAP small leak). Each code signals a different level of urgency and potential cost: misfires left untreated can damage pistons and the catalytic converter, raising repair costs into the thousands; a persistent P0420 can indicate a failing catalytic converter, also a high-cost repair if ignored; lean conditions (P0171) often point to vacuum leaks or fuel delivery issues that lower fuel economy and accelerate wear; EVAP leaks like P0456 are usually inexpensive to fix but, if ignored, can cause emissions failures and failed inspections. At Larry H. Miller Ford Lincoln Draper our expert team diagnoses codes quickly with OEM-grade tools, explains the true cause, and recommends the most cost-efficient repair plan. We often deliver lower total cost of ownership than independent shops by preventing repeat repairs, using genuine parts, and documenting repairs for warranty and resale benefits.

2014 Ford Mustang Check Engine Light Reset

Resetting the check engine light on a 2014 Ford Mustang without addressing the underlying fault can mask problems and lead to bigger failures. A reset clears the stored trouble code, but the condition that triggered the code remains and may recur or worsen. At Larry H. Miller Ford Lincoln Draper our approach is to diagnose, repair, and then verify the fix before clearing the code so you receive reliable, long-term service. We use OEM diagnostic procedures, perform road tests, and re-scan to ensure the repair holds. Choosing dealership service also protects warranty coverage, uses genuine Ford parts, and benefits from factory-trained technicians who understand Mustang systems and common fault patterns. We provide transparent estimates, clearly explain immediate and long-term savings, and offer service financing to make necessary repairs manageable.
