2025 Hyundai Elantra Check Engine Light Codes

Common check engine codes for the 2025 Hyundai Elantra include misfire codes (P0300–P0304), O2 sensor codes (P0130–P0167), and evaporative system codes (P0440–P0457). Misfires can reduce fuel economy and, if left unresolved, damage the catalytic converter — repair costs can escalate quickly. Faulty O2 sensors or catalytic problems reduce MPG and pass emissions testing failures, while evaporative system leaks often stem from a loose cap or defective purge valve.
