Mitsubishi 380 P0430 O2 Sensor Fault: How to Fix After Replacement

Model: Mitsubishi 380 Fault Code: P0430 Posted: 2017-09-28 22:31

Hi everyone, I own a Mitsubishi 380 and am currently receiving the P0430 diagnostic trouble code. I've already replaced the oxygen (O2) sensor, but the P0430 code persists. I'm looking for help to understand what might be causing this issue and how to resolve it properly. The P0430 code indicates a malfunction in the catalytic converter or an imbalance in the exhaust system, even after O2 sensor replacement. Could there be other underlying issues such as faulty wiring, engine misfires, or a clogged exhaust pipe? Any insights or troubleshooting steps would be greatly appreciated.
