What Does the P0430 Code Mean on Your 2024 Mitsubishi Eclipse Cross?
The P0430 code on your 2024 Mitsubishi Eclipse Cross indicates the bank 2 catalytic converter is not meeting its efficiency threshold. The 2024 Eclipse Cross continues with the 1.5L turbocharged 4-cylinder engine producing 152 horsepower and a CVT transmission. As an inline-4, bank 2 refers to the secondary catalyst monitor position. On a current-model vehicle, this code likely indicates a sensor or software concern.
Common Symptoms You Might Notice
- Check engine light on
- Minor fuel economy decrease
- Possible faint exhaust smell
- Normal driving behavior
- Emissions test failure
Most Likely Causes of the P0430 Code
A 2024 model shouldn't have converter wear issues.
- O2 sensor defect — A factory sensor out of spec producing inaccurate readings.
- ECM software calibration — Mitsubishi may have released updated software for the 1.5T engine platform.
- Catalytic converter defect — A manufacturing defect in the converter substrate. Covered under warranty.
- Exhaust system assembly issue — A loose gasket or connection from factory assembly.
How to Diagnose the Problem
Take the vehicle to your Mitsubishi dealer since it's under warranty. The dealer has factory diagnostic tools and TSB access for the Eclipse Cross. They will perform a comprehensive scan and evaluation of the exhaust system.
Repair Options and What to Expect
Your 2024 Eclipse Cross is covered under Mitsubishi's 5-year/60,000-mile bumper-to-bumper warranty and the federal emissions warranty (8 years/80,000 miles). All P0430-related repairs should be free.
