Code P0140
The code is Bank 1 Sensor 2 for the 02 sensor being bad on my 97 Chevy k1500. Which sensor is that exactly? It's hard to tell considering that there are only 3 on the truck. Two of the sensors are right off the manifolds and the last one is after the cat.
I replaced the one on the passenger side manifold and the one after the cat on the same side. The light still comes back on throwing the same code. Totally lost at this point...
