I know Cale has, but has anybody else? It's o2 Sensor Circuit Low Voltage, Bank 1 Sensor 2 which is the post cat sensor.
Nobody at Autozone had ever heard of it and could only suggest cleaning out the plug which I just got done doing.
The guy at Casper Electronics said possibly a fuse going bad but there's not a fuse for the o2 sensor that I know of, is there?
Everybody at Thunderracing is totally clueless about this.

I get one every time I exceed 80 mph wtf but if I reset it it stays away for about 500-1,000 miles. I don't know what causes it. My O2 sim came from www.floridapulleyheadquarters.com

I threw those codes when my o2's went bad.
