2016 Ford Focus ST Check Engine Light Reset

The check engine light reset on a 2016 Ford Focus ST isn’t just a button press — it’s confirmation that an underlying issue was diagnosed and resolved. At Larry H. Miller Ford Lincoln Draper in Draper, UT, we use OEM-level diagnostic tools to read and clear fault codes only after recommended repairs are completed, ensuring the light doesn’t return due to a missed fault. Resetting the light yourself with a handheld tool or battery disconnect may silence the indicator temporarily, but it won’t fix root causes like failing oxygen sensors, ignition misfires, or emissions control faults. Choosing our dealership means you get transparent estimates, factory-trained technicians who follow Ford service procedures, and genuine OEM parts that preserve vehicle performance and resale value. We also honor warranty requirements — repairs covered by warranty must be completed at certified dealerships to remain valid. For convenience, explore our current service specials and schedule service online; our team will provide a clear timeline and explain how correct repairs today deliver immediate and long-term savings by preventing repeat visits and bigger failures later.

2016 Ford Focus ST Check Engine Light Codes

Common check engine light codes for the 2016 Ford Focus ST include P0300 (random/multiple misfires), P0420 (catalyst system efficiency below threshold), P0171/P0174 (system too lean), and P0130–P0167 series codes related to oxygen sensors. Each carries potential costs if left unaddressed: misfires can ruin your catalytic converter and lead to expensive replacements; oxygen sensor issues reduce fuel economy and increase emissions; lean condition codes can point to vacuum leaks or fuel delivery faults that escalate into engine damage. At Larry H. Miller Ford Lincoln Draper in Draper, UT, we assess each fault with factory diagnostics, explain the cost-benefit of repairing now versus delaying, and provide transparent estimates that often save you money compared with repeated independent repairs. Our service team focuses on durable fixes using genuine Ford parts, which preserve vehicle longevity and minimize repeat visits. To make repairs manageable, we provide service financing and regularly updated service specials.
