O2 Sensor and Catalytic
Sorry, I’ve had lots of questions, never had a car before where I could get codes and most of them where much simpler than this Scion.
Had the misfire issues earlier and that seems to be fixed, thanks for all the help on that! Earlier it also had the P0138 code High Voltage O2 Sensor.
I drove it to work yesterday about 80 mile round trip and it ran fine. Checked codes today and it still has the P0138 but also has P0420 Catalytic system Below Threshold.
So would the best option be to replace the O2 Sensor?

ok thank you, I was leaning towards replacing them and hoping it’s not the catalytic converter, but if it needs replaced I guess it needs replacing.
