2015 Lincoln MKZ Hybrid Check Engine Light Codes

The 2015 Lincoln MKZ Hybrid can present a range of diagnostic trouble codes: oxygen sensor (P0130–P0167) related to emissions and fuel trim, EV/hybrid battery or inverter codes, misfire codes (P0300–P0312) and evaporative system faults (P0440 series). Ignoring these codes risks reduced fuel economy, increased emissions, and progressive component damage such as catalytic converter failure—repairs which can be significantly more expensive than timely fixes.
