I don't know much about Focus cars yet. I have a 2012 Focus Hatchback Titanium. It has 223K. Yes 223K. Runs and drives like new. The engine light went away today and it still is driving great but I know I still need to test the o2 sensors while the car is running. I have a Duratec 2.0 4 Cylinder. Not sure what the model is. I have the weird DPS6 or DSP6 transmission but it seems to be working well (knock on wood). I paid $1400 for it and it's loaded with all the bells and whistles. You can even see the leather looks brand new instead of looking like 223K. The body looks great and suspension feels like new. Pics:

Looks great!

At 223K I would not be surprised if your catcon issue is really a lazy/dying O2 sensor issue as I listed in my previous post. Should be easy to check with a scanner looking at live data.

Let us know

Catalytic Converters error code- what should I do please?

I have a 2016 Escape. I had a P0420 code but it wasn’t from the cat or O2 sensor. Two different shops said my fuel pressure was too high. They couldn’t figure out why. It ended up being a gummed fuel rail and partially clogged injectors. I fixed it with K100, a fuel stabilizer. The gum was from the ethanol in our fuel.
Though my mileage was 55k when this happened.

So basically the only way to really diagnose this is with a scanner that can read live data.

Ok so today I hooked up my bluetooth OBDII scanner and read some live data. Oxygen Sensor 1 and Oxygen Sensor 2 report different things? Or maybe I need a better Android Scanner? I have a few free scanner apps but none of them would give me live data and the one that did give me data, was confusing.

Here is the live data that I got. Oxygen Sensor 1 Wide Range Current WAS moving around but Oxygen Sensor 2 didn't have a current category. I did notice that Oxygen Sensor 2 has Short Term Fuel Trim that says N/A.

You have to be able to see the swings in absolute highs and lows there and more importantly the amounts of swing to be able to tell the sensor action, only graphing can show that.

I question the validity of the 420 code given on the Escape, should have been showing lean codes or fuel trim limits instead for injectors clogged up. They show much faster than a 420 does.

It would be hard to diagnose without live data.

This actually was live data, I just took a screenshot of it. The current of the one oxygen sensor was moving between 0.02 to 0.09 which is what I told it should do. However the other oxygen sensor does not measure that. There were other numbers moving too. I couldn't make a video of it. I'm questioning why one of the o2 sensors gave a N/A message?

If I now need a graph, can anyone recommend an Android OBDII app that will do this?

I will say this, and I don't want to derail people from thinking what my problem is, but my exhaust can get loud at times. Not when I hit the gas down hard, but for example, if the car is in an overdrive gear and I get on the gas enough that it doesn't shift down but it does make a deep throaty exhaust note. Might be normal or might be a leak? Maybe a donut gasket.

But what I'd like to do is rule out an o2 sensor so if anyone can recommend an app that'll do this, I'd be glad to download it. Thanks!

Bank 1 sensor 2 would be the one that would trigger the code.
Bank 1 sensor 1 is the sensor before the cat. Sensor 2 is the one you need to monitor.

The reason for the NA message is because sensor 2 doesn't monitor fuel trim its only job is to monitor the effectiveness of the cat.

Sensor 2 bank 1 only measures Voltage and short term fuel trim which it says N/A. Should it be measuring current as well? This is why I think I need a different app for scanning live data. I'd even be willing to pay for an app that does this.

This video explains it pretty well but yeah you need to be able to monitor the voltage of sensor 2. It sounds like sensor one is working just fine.
