2010 Ford Fusion Check Engine Light Codes

At Larry H. Miller Super Ford Salt Lake City we see common check engine codes on the 2010 Ford Fusion such as P0420 (catalyst system efficiency), P0171/P0174 (fuel trim/lean condition), P0300–P0304 (misfires), and P0130–P0167 (oxygen sensor issues). Left unresolved, a P0420 can lead to reduced fuel economy and eventual catalytic converter failure—an expensive repair that often far exceeds the cost of timely diagnostics. Lean codes like P0171 increase engine strain and emissions; misfires (P0300 range) can damage pistons and catalytic components if driven for long periods. Our certified Ford technicians use OEM-level diagnostic tools that read freeze-frame data and live sensor output to identify root causes instead of guessing. That accuracy delivers immediate savings by reducing unnecessary parts replacement and long-term savings via fewer return repairs and extended drivetrain life. We make service transparent—estimates, part options, warranty information, and available service specials are shared before any work begins.
