2010 Ford Mustang Check Engine Light Codes

At Bill Estes Ford Brownsburg in Brownsburg, IN, our certified technicians routinely diagnose common codes that illuminate the check engine light on a 2010 Ford Mustang. Typical stored codes include P0171/P0174 (lean condition) from vacuum leaks or failing mass airflow sensors, P0420 (catalyst system efficiency) tied to oxygen sensors or catalytic converter wear, and ignition-related codes like P0300 (random/multiple misfires) from worn spark components. Left unaddressed, a P0171 can lead to poor fuel economy and long-term engine deposits, costing hundreds in fuel and potential intake repairs; a P0420 can evolve into catalytic converter replacement, which is significantly more expensive than early oxygen sensor replacement; and persistent misfires can damage the catalytic converter and reduce engine life. Our approach at Bill Estes Ford Brownsburg is to diagnose accurately, explain costs and options transparently, and use OEM parts to restore efficiency. Choosing our dealership often costs less than independent shops in the long run because accurate initial diagnostics prevent repeat visits, extend component life, and preserve warranty coverage.

Check Engine Light Flashing

A flashing check engine light on a 2010 Ford Mustang is a sign of a severe misfire or an issue that risks immediate damage—do not ignore it. Flashing typically indicates unburned fuel entering the exhaust, which can overheat or destroy the catalytic converter and lead to costly repairs. At Bill Estes Ford Brownsburg, we recommend pulling over safely, limiting speed, and bringing the vehicle in promptly so our technicians can perform a priority diagnostic. We provide transparent estimates, OEM parts, and factory-trained technicians who understand Ford powertrains. To help with urgent repairs, we offer service financing options and rotate service specials to reduce out-of-pocket expense. Our customer experience prioritizes quick turnaround, clear communication, and long-term value—items you won’t get from unverified shops. If your check engine light is flashing, contact us or schedule service immediately to prevent further damage and get back on the road with confidence.
