2004 LS430 O2 wiring harness diagram
My bank 1 sensor 1 O2 sensor connector harness wires have pulled out of the plug. I need to find out which wire goes to which pin. Anyone have a wiring diagram for this?

Hello,
I Have the same Problem on my 04
I connect anything something wrong
to confirm
ox2 on ox1a = blue on sensor this is the black shielded on harness car side
e1 on 01A = white on sensor this is the brown on harness car side
is this so correct ?
i connected it so but sensor reads in techstream always only 0.07V
I connectet it at first wrong maybe i killed my ECU ?
Testet 2 o2 sensors the new one (what i connectet wrong) and the old one!

What you described is correct, but please note that there are 2 black wires on the harness-side (pin 2 and pin 3) - first check to make sure they are in the correct spot.
Are you getting any DTC's (Diagnostic Trouble Codes) like P0031 or P0032? Attached are troubleshooting procedures for the O2 sensors...

do you have an image of the stock location on the pins on the plug from the car?
