| 26-FL-003H TSB | 2026-07-08. Service bulletin. ELECTRICAL SYSTEM; ENGINE. Some Kona (SX2) vehicles equipped with the 1.6L T‑GDI engine may exhibit false “engine left idling” notifications in the MyHyundai app, even when the engine is not running, due to a logic error associated with the front oxygen (O₂) sensor. This condition may also illuminate the Malfunction Indicator Lamp (MIL) and set DTC P223700 (O₂ Sensor Pumping Current Circuit/Open [Bank 1 Sensor 1]). This bulletin provides instructions to perform an ECU software update to correct the O₂ sensor logic and resolve the condition. |
