    I have a 2000 Silverado 2500 4wd. The SES light came on, and is indicating codes 160 & 161. They both refer the the post converter O2 sensor, right bank. 160 says there is no voltage, and 161 says the O2 heater is not working. This sounds like I need to replace the O2 sensor. I see the two sensors behind each converter, I'm wondering which is the right bank. I assume this refers the the left & right bank of cylinders (6.0L gas). I can trace the pipe back to the engine, but I'm unsure which is considered the right side. I'd be grateful for any help - Jason

    The right bank would be the bank of cylinders on the passenger side of your truck or the even (2,4,6,8) bank.

    as said above right side is the passenger side. Whenever the mention of side comes into play you have to pretend you are sitting in the drivers seat ready to drive. :drinkup:


    Very commom for the heaters to go in the o2 sensors. In my 98 I've replaced all 4 of them, acually the post cat ones have been changed twice.

    Thanks for the help.. it was the right bank post cv. sensor. Pretty easy replacement, cleared the codes and the problem seems to be gone.
