Hey All!

So still trying to figure out some possible driveability issues -- came across this PID (under OBDII Live Data):

SHRTFTB1S2 = N/A

As far as I know, this sensor, if it was working, would show cat efficiency. From research across the web I hear everything from "this parameter has no value" to "you need a new catalytic converter."

I guess my first plan here is to ask around -- anyone here with a stock 2018+ be willing to pull up this PID and let me know if they also get N/A? Thanks so much!
