2015 Civic Si with a rv6 catted down pipe
So I turned on my secondary o2 sensor but kept everything else on my tune the same and was going to get inspected but after driving around for a short while I got code P0139.
I'm reading that means the secondary o2 sensor is possibly bad?
I can't clear the code.
I've had the o2 sensor off for a year now using a tune by vit.
Am I screwed or what can I do?
