2022 Hyundai Ioniq Plug-In Hybrid Check Engine Light Reset

The check engine light on a 2022 Hyundai Ioniq Plug-In Hybrid can be reset with an OBD-II scanner or by addressing the underlying cause and allowing the system to clear stored codes. While simple resets are possible at home, doing so without a full diagnosis risks masking recurring faults and voiding warranty coverage for related repairs. At Courtesy Hyundai of Tampa, factory-trained technicians use OEM software to read freeze-frame data, confirm repairs, and clear codes correctly so the vehicle’s hybrid management systems recalibrate as intended. Choosing dealership service delivers peace of mind, long-term savings on fuel and repairs, and ensures warranty-protected work is documented and performed to factory standards.

2022 Hyundai Ioniq Plug-In Hybrid Check Engine Light Codes

Common check engine codes on the 2022 Hyundai Ioniq Plug-In Hybrid include P0420 (catalyst efficiency), P0300 (random/multiple misfires), P0171 (system too lean), P0455 (large EVAP leak), and various oxygen sensor codes. Ignoring P0420 or misfire codes can lead to expensive catalytic converter replacement or engine damage — costs that escalate from a few hundred dollars for sensors or EVAP repairs to over a thousand for converter replacement. Prompt dealer diagnosis reduces parts misidentification and repeat labor, saving money over time. Our technicians use OEM parts and hybrid-specialized procedures to ensure accurate repairs and preserve warranty eligibility, which requires work to be done at a certified dealership.

2022 Hyundai Ioniq Plug-In Hybrid Check Engine Light Flashing

A flashing check engine light on your 2022 Hyundai Ioniq Plug-In Hybrid typically indicates a severe condition, most often an active engine misfire that risks damaging the catalytic converter. When you see a flashing warning, reduce speed, avoid heavy loads, and bring the vehicle to Courtesy Hyundai of Tampa immediately — continued driving can increase repair costs dramatically. Our service team prioritizes flashing-light diagnostics to prevent secondary failures and preserve hybrid system integrity. Because warranty-covered repairs must be completed at a certified dealership, bringing the vehicle to our factory-trained technicians protects your coverage and often results in lower total repair costs compared with repeated independent attempts to find intermittent faults.
