O2 sensor bank 1 sensor 1 wire colors

Asked by Chris Aug 22, 2020 at 01:12 PM about the 2006 Ford F-150 XLT SuperCab Flareside 4WD

Question type: Maintenance & Repair

Can someone please help. I've seen too many diagrams
and read every blog I can find and just getting confused. I
need to know a simply as possible what my passenger
side o2 sensor bank 1 sensor 1 wires from the wire
harness close to the PCM running to the coupler and then
to the sensor should be. Like the red wire with the yellow
stripe goes to the grey wire on the sensor, red/white to
black, grey/red to whatever and grey/blue to this. Etc... I
know those are the four colors from the firewall and that I
have 2 white, black and grey in the sensor so again simple
as can be what mates to what please and thank you.

black and gray are the ones you want. Do you have a scanner? you can take a test light to bat voltage and connect it to the red wire and the yellow wire. the correct sensor wire will show 1.2 on the scanner. but i think the red/gray or red/yellow goes to the black. the white ones are heater wires
