I have a 2001 Silverado 1500 4WD 4.3 p/u. I need to replace a downstream bank 2 sensor 2 oxygen sensor. I am wanting to see if someone can provide me with an illustration of the location of this sensor? I am thinking that it is the back passenger one but I wanted to verify. Thank you.

 

Bank 2 is the passenger side. Sensor 2 or downstream is the sensor just past the catalytic converter.

 

Is this picture sensor location accurate for my p/u?

 

Yes, it looks good.
