Any useable codes from a regular OBD2 reader?

[Topless]

The Acton pocket reader is my preferred diagnostic tool. Only the info I can use and nothing beyond my backyard wrench status that will cause me to overthink a problem and change a bunch of unnecessary parts. It is always in my car.

That said, I think it is unlikely that a bad O2 sensor is causing your code. You can pull it and do a visual inspection but P0430 usually means a weak/failing/sooted cat. If the sensor is failing you will usually get an "aging sensor" code instead.

Good luck!

I bought a RioRand from Amazon and downloaded the Torque Pro app on my tablet.It works on Bluetooth.It works fine and it will clear codes.I bought it before I had the IMS changed. I wanted to know right away what the code was if it flashed. Mike is right though. The Durametric is the one to buy if you plan on doing a lot of DIY.
