P0430 on Your 2024 Jeep Compass Explained
A P0430 code on your 2024 Jeep Compass means the Bank 2 catalytic converter efficiency is below the ECM's threshold. The 2024 Compass uses a 2.0L turbocharged inline-4 engine producing 200 hp. On this engine, Bank 2 refers to the secondary catalyst section, monitored by a downstream O2 sensor.
On a brand-new 2024 model, this is uncommon and should be handled under warranty at your Jeep dealer.
Symptoms
- Steady check engine light
- Possible slight fuel economy decrease
- Faint exhaust odor possible
- No noticeable performance change
- Would fail emissions test

- Catalytic Converter Defect — A below-spec converter from the factory.
- ECM Software Issue — The new 2.0L turbo engine may need a calibration update.
- Exhaust Assembly Issue — Factory assembly problems with gaskets or connections.
