2016 Ford Focus Check Engine Light Codes

Common codes for the 2016 Ford Focus include P0420 (catalyst efficiency), P0300 (random misfire), P0171 (system too lean), and P0455 (large EVAP leak). Ignoring these codes risks escalating costs: an unresolved P0420 can lead to a catalytic converter replacement that may exceed $1,000, repeated misfires (P0300) can destroy pistons or the converter, and persistent lean conditions reduce fuel economy and accelerate engine wear. At Larry H. Miller Ford Lincoln Draper, Draper, UT, our certified technicians use OEM diagnostic equipment to translate codes into precise repairs and help you avoid long-term expenses. We focus on transparent estimates, offer factory parts, and highlight immediate versus lifecycle savings so you can make informed choices.

2016 Ford Focus Check Engine Light Reset

Resetting the check engine light on a 2016 Ford Focus with a scanner clears the code but does not fix the underlying issue.

Miller Ford Lincoln Draper, our technicians perform a full diagnostic before any reset, ensuring the root cause is addressed with OEM parts and factory procedures. That purposeful approach protects your warranty and prevents costly repeat visits.
