2022 Hyundai Ioniq Plug-In Hybrid Check Engine Light Reset

The check engine light reset for a 2022 Hyundai Ioniq Plug-In Hybrid is straightforward when performed correctly: a reset should follow a confirmed repair, not precede one. At Larry H. Miller Hyundai Peoria in Peoria, AZ, our approach is to diagnose and repair the underlying fault first—whether it’s a sensor, ignition, emissions part, or a hybrid-system related issue—then clear codes so you leave with a lasting fix. DIY resets can mask intermittent problems, lead to missed warranty coverage, and fail to address hybrid battery or power electronics concerns specific to plug-in models. Our technicians use Hyundai OEM software to record repairs, validate system health, and apply precise resets that preserve warranty eligibility. You’ll receive a clear explanation of the fault codes, written estimates, and options to use service financing if desired. Check our current service specials, and when you’re ready, schedule service online for a timely, transparent visit that protects your car’s longevity and resale value.

2022 Hyundai Ioniq Plug-In Hybrid Check Engine Light Codes

Common codes for a 2022 Hyundai Ioniq Plug-In Hybrid often include oxygen sensor faults (P0130–P0167), evaporative system leaks (P0440 series), and hybrid system or inverter-related codes. Left unaddressed, oxygen sensor or catalytic converter issues reduce fuel efficiency and can cause costly converter replacement; EV-system faults can lead to reduced electric range or charge problems that are more expensive to repair if delayed. At Larry H. Miller Hyundai Peoria our certified technicians in Peoria, AZ, use factory-grade scanners and safety procedures to identify whether a code is a simple sensor replacement, a wiring/connector repair, or a more involved hybrid-system intervention. We explain immediate repair costs and long-term savings—fixing a sensor early often prevents catalytic damage and maintains the Ioniq’s optimal 29-mile electric range— and provide OEM parts and warranty coverage for peace of mind. Book an inspection, take advantage of our service specials, and schedule appointment online for efficient, expert care.
