O2 heater circuit code
Have an issue with my 98 Expy 5.4L. I have a CEL (P0141) I'm attempting to resolve. Replaced sensor and reset the computer. A few miles later...same code. Is there a fuse for the heater circuit, and what is the best way to clean those hard to reach blue connectors.

Well, I understand P0141 is bank 1 sensor 2 , so I did some looking on other posts and some asking around to find that it was driver side post-CAT.
Good grief, I hope I didn't replace the wrong one

You did! Bank 1 is always the side of the engine that has cylinder #1. In our case with these 4.6L and 5.4L engines, cylinders 1-4 are on the passenger side. If you still have the one that came out, it's obviously good and can be used.

Welp, I guess I will be doing some sensor swapping soon. I will keep you posted! Thanks for the info! Between the research and actually installing the sensor on, I must have had an episode of dyslexia. Oh well...it happens. And yes, I did keep the old one for that very reason!
