P0430 on Your 2024 Ford Maverick
A P0430 code on the 2024 Ford Maverick indicates the engine control module detected below-threshold catalytic converter efficiency on Bank 2. The 2024 Maverick comes with the 2.5L hybrid four-cylinder (191 hp combined) or the 2.0L EcoBoost turbo four-cylinder (250 hp). Both are inline engines, and the Bank 2 designation refers to the ECU's secondary catalyst monitor.
On a brand-new compact truck, converter failure is virtually nonexistent. This is a sensor defect, software issue, or assembly problem, all fully covered under warranty.
Symptoms You May Notice
