2016 Hyundai Sonata Hybrid Check Engine Light Codes

Understanding common codes helps you prioritize repairs for your 2016 Hyundai Sonata Hybrid. Typical codes include oxygen sensor (P0130–P0167), catalytic efficiency (P0420), misfire (P0300–P0312), and hybrid system warnings. Left untreated, oxygen sensor faults reduce fuel economy and can damage the catalytic converter—raising repair costs by hundreds of dollars. Misfires risk engine damage and poor performance, while hybrid system warnings can signal issues that, if ignored, shorten battery life and increase replacement expense dramatically. At Arapahoe Hyundai in CO we quickly map codes to recommended fixes, explain cost and time implications, and highlight immediate and long-term savings of addressing issues early.
