wel i called the dealer ship and they guy said i changed the correct one. I double checked all the connections and plugs to.
The Upstream oxygen sensor heater fault(right bank) is the senser closest to the front of the car, correct??

Like I said, the one you changed is NOT the correct one. If you look on this link http://www.courtesyparts.com/A32_O2-sensors.html the one closest to the front (near the radiator) is the LEFT sensor. The RIGHT bank sensor is the one by the oil pressure switch, http://www.motorvate.ca/mvp.php/514 (near the oil filter area)

The sensors are the same (look on http://www.oxygensensors.com), the only difference is the length of the wire. The ones you buy from a Nissan dealer have a perfect length so the wire isn't dragging somewhere. One wire is shorter than the other (so 2 different part numbers). The ones you buy from http://www.oxygensensors.com are the ones with the long wire so they would fit in both places (one wire might be dragging, not sure)

ya thats what i kinda figured, tomoro im gona spice the wires with the broken one with the sensor i took out today sense it is still good. I realy got nuthing to loose cause the sensor i have is usless and the one in the car is broken.

****UPDATE*****
ok , i changed the sensor today without even having to do any spilcing and everything fit perfect. Problem is im still getting the same codes for the right bank sensor and the knock sensor. So now im thinkin my knock sensor is causing both codes.
Also i have an air fuel gauge, it used to bounce around, now it stays at stoich and goes to lean at high rpms. is this normal?

You replaced the one halfway down the y pipe, not the one closest to the front of the car, right? You didn't bust the sensor installing it, did you? I once sprayed WD40 on a 02 sensor trying to screw it in, and I think that screwed it up? There were no visible signs of damage, but I kept getting the code. I bought a new sensor, installed it with antiseize, and that fixed it.

Make sure you have premium fuel in your tank and do the knock sensor resistor mod and see if that solves your problem. If it does, then your KS is bad. If it doesn't, then the KS is still good and there might still be a problem with the O2 sensor.

Also, the knock sensor will NOT throw 02 sensor codes. Only failing 02 sensors throw o2 sensor and knock sensor codes. If the knock sensor code is thrown by itself, then it's a problem with the knock sensor or harness.

damm i think im gona buy another 02 sensor now cause of it banging around with my tools and on the floor.
The weird thing is i think i had the knock sensor code and then later got the 02 code. Im gona change the knock sensor sence i already bought it a while ago and see what happens.
