Hello,
I have a check engine light producing two codes:
P0141 - O2 Sensor Heater Circuit ( Bank 1 Sensor 2)
P0054 - O2 Sensor Heater Circuit Resistance
I am having a hard time finding any repair manuals or guides to replacing the sensor efficiently without disassembling too much of the intake assembly covering the whole back. I figured out that the sensor is before the Cat Converter as it is sensor 2. But I am not sure if the O2 heater circuit has a fuse associated before I directly go to replace the part.
I would like to know if there is a fuse and if so, what fuse is it?
Also how long would it approximately take and what would be a reasonable cost to repair at a shop that isn't a dealership?
The Ford dealership is wanting to charge $386 with parts plus labor.
Thank you,
