SERVICE ENGINE SOON

On my way to work this morning about halfway through my trip my service engine light came on...... Don't really know why nothing seems wrong with the Stang and she runs great. Only issue I've seen lately is my pcv valve has quite a bit of oil sputter around it and the hose collapses. The pcv valve is only 5 months old.

My question to all you mustang guys is can I use my Predator tuner to check the service light?

My trouble code says P0430 Catalyst System efficiency below threshold bank 2

Is that a O2 sensor?

Re: SERVICE ENGINE SOON

Yes, Basically this means that the oxygen sensor downstream of the catalytic converter on bank 2 is detecting that the converter is not working as efficiently as it should be

Sounds like your cat is bad, or are you catless?
