My ford F150 2015 3.6 Ecoboost has
Code: P0430 - Catalyst System Efficiency Below Threshold (Bank 2)

I ran test and I'll share photos, hoping somebody can tell me what my problem is. To me it looks like my catalyst is bad, hoping someone can help me to confirm..

 

It's likely that the converter ain't converting any more.

If you're under 8 years from in-service date and under 80K miles and in the US (but not in California - 7/70), they're still under warranty.

 

How is your truck running? Just curious what symptoms the ruck may have.

 

My truck has high milage 251,000 miles. I had to replace 2 coils and i did all 6 new spark plugs. Before I did that it misfired quite a bit, and when I brought it to mecanic it was on limp mode last few miles. But i drove a few 100 miles after new coils and plugs, till check engine light came on because of this, I deleted code and cleaned the sensor on cat, but it wasnt very black. once and again I drove bit over 100 miles till it came on again. But as far as I can tell the engine is running good.

 

Yep. Cat has been ruined due to excessive fuel dumped into the exhaust.

If you don't care about actual emissions, you can install an anti-fouler on the downstream sensor and that will usually fool the system enough to keep the light off.

You can also try one of those miracle-in-a-can cat cleaning products and see if it helps. Sometimes, they do as do other various possible cleaners.

 

Okay thanks, no I dont care about emissiones, living in Chihuahua Mexico, no laws about emissiones here in the country.
I ve read that I can damage motor if I keep running damaged cat, do you have info on that?
Id sure like if I could get a cheaper fix then new catalytic converter.

 

Nope. As long as the catalyst substrate hasn't melted or crumbled and is simply inert, there is no risk of any downside.
Anti-fouler or two to turn off the light. If the light doesn't bother you, then do nothing as long as there are no other symptoms.
