What Does P0430 Mean on Your 2022 Hyundai Kona?
Your 2022 Hyundai Kona has set a P0430 code, indicating the catalytic converter on Bank 2 isn't meeting efficiency standards. The 2022 Kona comes with a 2.0L naturally aspirated 4-cylinder (Nu engine) producing 147 horsepower, or a 1.6L turbocharged 4-cylinder producing 195 HP in the N Line. On these inline-four engines, Bank 2 refers to the secondary catalyst monitoring position in the exhaust system.
