Hi Guys I知 new to the site I知 looking for a color code chart for my 2005 f150 bank 1 sensor 1 o2 sensor can anybody direct me on how to find it any help would be appreciated thank you
I have O2 wiring issues, driver side upstream sensor wires are black/grey/white/white. Below is a picture of my engine bay harness. Which wires go to my sensor wires? Any assistance would be greatly appreciated. Thank you
The reds are your o2 heater wires, red white stripe pin 1 on plug red yel stripe pin 2 on plug
the white blu stripe pin 3 on plug sensor wire
gray red stripe is pin 4 sensor wire
most likely you have a blown fuse on heater wires
