o2 Sensor BS

[PearlDrummer00]

So my ecu threw a code.....2 blinks....o2 sensor number two right? well i went ahead and replaced it about a month ago.....now its throwing the same exact code. :wtf: .........i installed EVERYTHING Correctly. Its kinda a no brainer but i used a bosch universal sensor....could these have some sort of default against imports? Looking for some input please.

when you get O2 sensor code, it is a good idea to replace both of them at the same time.
make sure you replaced a correct one.
