The check engine light flashing on your 2015 Subaru Impreza signals a potentially serious condition such as a severe misfire that can damage the catalytic converter or cause unsafe driving.

2015 Subaru Impreza Check Engine Light Codes

At Mike Shaw Subaru Greeley we frequently encounter specific codes on the 2015 Subaru Impreza that indicate common faults: P0171/P0174 (lean conditions from vacuum leaks or MAF sensor), P0300–P0304 (misfires from coils or plugs), P0420 (catalyst efficiency), and oxygen sensor codes affecting emissions and fuel economy. Ignoring these codes can escalate repair costs — a simple oxygen sensor replacement is far less expensive than replacing a failed catalytic converter, and correcting misfires promptly prevents damage to multiple engine components.

Choosing Mike Shaw Subaru Greeley often results in lower overall cost than repeated repairs at independent shops because we find the root cause quickly and use OEM parts backed by warranty.
