2014 Ford Raptor Check Engine Code

[crookedAVI]

Hey guys

I have a 2014 raptor with around 200K miles on it

I recently got a check engine light pop up (of course a week before my inspection is due) and i checked the codes:

P0420 and P0430

What are the chances its just my downstream and upstream O2 sensors?

If im being honest, im not looking to spend money on a new cat if thats the issue

It could also be an exhaust leak maybe? just based on what im reading.

Any advice would be great! Thanks

Assuming this is not a prius.......

But




Nobody is ever looking to spend money on a cat so....



Clean the MAF sensor

How old are the O2 sensors? If original then they might be issue, they are tired. Thats the first thing I would swap out.

How old are the plugs and wires? They might not be burning as efficiently as needed.

These are the two first things to check, least cost vs. A cat.

my 0420 code is because the wires to one of my o2 sensors is broken. havent bothered with it yet, but i saw its completely broken.

Those codes usually point to catalytic converter efficiency, but it could be bad O2 sensors or an exhaust leak .I’d check for leaks and test the sensors first before replacing the cats!

The stock cats are pretty stout. Only a hand full of owners reported any issue.
And most of that was from off-roading hard and/or hitting something.
In most cases it's a lazy or just plain bad O2
Wire damage to the O2s is common, the wire is very thin and fragile.
