B1S1 oxygen sensor issues. (Sorry for the x-post)
I got a code for my wifes 2010 justa (199000 miles, first replacment!) for the B1S1 oxygen sensor. I ordered one and installed it.
Code gone... Next day CEL comes back on. I grab my dongle and its now P0420! I replaced the cat/manifold about 40k ago.
I head to graphing in torque, and the sensor isnt reading at all. Im assuming that its that way until up to temp, so i go on a 20 min drive, still no voltage, its using the assumed maps.
I head to newtis.info and check wiring diagrams, as there are 6 wires, and the original code was for "oxygen sensor pump failure(??)". The wiring diagram does not explain what wire does what. There are 2 yellow, 2 white, one orange and one black.
Can someone help me out with wire assignments so i can check voltages?
I would like to know if i have a bad out of the box sensor, or wiring issue. Or is there a fuse for the oxygen sensors? B1S2 varies up and down with normal graphed voltages.
Id love to hit 300k with it. My 04 x3 is at 202k
