P0430 on the All-New 2024 Ford Ranger
A P0430 code on the redesigned 2024 Ford Ranger means the powertrain control module detected below-threshold catalytic converter efficiency on Bank 2. The 2024 Ranger is a complete redesign featuring the updated 2.3L EcoBoost turbocharged four-cylinder engine producing 270 horsepower. As a four-cylinder, the Bank 2 designation relates to the ECU's secondary catalyst monitoring point.
On a brand-new truck with a redesigned platform, converter failure is virtually impossible. This is a sensor defect, software issue, or assembly problem that should be covered under warranty.
Symptoms You May Notice
