2019 Hyundai Ioniq Plug-In Hybrid Check Engine Light Codes

Common check engine light codes for a 2019 Hyundai Ioniq Plug-In Hybrid include O2 sensor faults, EV battery/charging system codes, misfire codes, and emissions-related codes. Left unaddressed, O2 sensor failures can decrease fuel efficiency and raise emissions; misfires can damage the catalytic converter and lead to much higher repair bills; charging system faults can reduce electric-only range and increase hybrid system wear. At Arapahoe Hyundai in CO, our technicians quickly translate codes into clear repair recommendations so you understand cost vs. benefit.
