P0430 on Your 2024 Ford Bronco
A P0430 code on the 2024 Ford Bronco means the powertrain control module detected below-threshold catalytic converter efficiency on Bank 2. The 2024 Bronco offers the 2.3L EcoBoost turbo four-cylinder (275 hp), the 2.7L EcoBoost twin-turbo V6 (310 hp), or the Raptor's 3.0L EcoBoost V6 (418 hp). On V6 models, Bank 2 is the cylinder bank opposite cylinder 1.
On a brand-new off-road vehicle, converter failure is virtually impossible. Sensor defects, software issues, or assembly problems are the likely culprits, all covered under warranty.
