2005 5.4 O2 Bank 1 Sensor 3
Where is this sensor located? Ran TorquePro app on my system and this one came up dead, no reference voltage. I replaced the upstream O2's when I did plugs at about 70k. Got 94k on truck now. Replaced all the fuel injectors and fuel filter about 1k ago(extended warranty on 05 F150 injectors was running out). No CEL and no codes stored.

There is no bank 1 sensor 3.
They only have pre and post cat sensors.
I would assume it means bank 1 sensor 2 which is the looking at the truck motor left side after cat sensor.
