Is bank 1 in the front and bank 2 in the back when the northstar is installed in the engine bay?? Of corse on my 96 STS that is.:thepan:

Bank 1 is the right bank (firewall side). Bank 2 is the left bank (radiator side).

ok i am asking because i just replaced the o2 sensor (on bank 2) and i am still getting code 147. It's just annoying seeing that check engine light. I'm also getting a code 603 i believe. WTF.
Thank you for the info.

P0147 - Heated Oxygen Sensor (HO2S) Heater Performance Bank 1 Sensor 3
That is the aft-CAT sensor.

After CAT, easy fix on a lift, $50 + or -, from any of several suppliers in here.....

OK, I see now, i replaced the wrong one. My bad, THANK YOU for letting me know, i will have to pick up another one and replace that one.

You guys ROCK

Just as an aside, as long as you'll do the after CAT sensor, why not do the remaining bank sensor so they're all 3 "new" and hopefully sending the same voltage signals.......O2 sensors do get "lazy".
