Hello - I tried some quick searching, but can't find my answer. Hoping it's an easy one. Just bought a 2013 Ecoboost a little over 6 months ago and over the weekend the Engine light came on. Had it read and it was P0430 indicating the LH converter is bad. My question is, there was 3 of this same exact code. Does that mean the code has come on 3 times prior and then turned off? It has since turned off when the weather warmed up.


Thanks.
Ryan

 

What did you read your DTC’s with ?

 

Took it to an auto parts store. They used Actron AutoScanner Plus from what I remember.

 

It means their scan tool hiccupped or needs replacing. The pcm will only store 1 code for each malfunction.

Or they wanted to sell you 3 of the same part..

 

And converters don't just fail. There is an underlying issue to make the converter fail if in fact it did.

 

Yeah.. like an un-corrected mis-fire that allowed raw fuel to be dumped into them...

 

It's rare but I have personally experienced failed converters with no underlying cause a few times over the 11 years I worked at the dealer.

I just bought it a little over six months. First thing I did was changed plugs based on some of the feedback I saw on here. They were gapped all over the place. The tricky thing is that it turned off once the weather warmed up. I tried to call the dealer to get it diagnosed but they told me they might not be able to tell me what the issue is if the light isn't on.
