Ford PO430 Code - Catalyst System Efficiency Below Threshold. How Can I Fix It?
#1
Hey everyone, I’ve got this PO430 code showing up on my Ford F-150. I have no idea what it means exactly, but from what I’ve heard, it might be related to the catalytic converter. Could it be something else causing this? I’m hoping it’s not the cat because, let’s be honest, those things aren’t cheap! Has anyone dealt with this before? Any other things I should check before assuming it’s the converter? Maybe an O2 sensor or some other part?
