2016 Hyundai Elantra GT Check Engine Light Codes

Common check engine light codes for a 2016 Hyundai Elantra GT often point to oxygen sensors (O2), catalytic converter efficiency, misfires (P0300-series), or EVAP system faults. Left unaddressed, O2 sensor failures reduce fuel economy and can damage the catalytic converter—costing significantly more in repair than prompt sensor replacement. Misfires can cause rough running and long-term engine wear; timely attention preserves performance and avoids engine damage. EVAP issues can lead to failed emissions tests and wasted trips to the test center.
