I cleared the code and took the car around the neighborhood. No engine light. But when I stopped and checked the codes, it was back. When I started the car again, the engine light was on.

So, if it's the heater in the probe then the probe needs replaced. I can check the fuse, if I knew where/which to look for. Any thoughts?

The connectors will require so much removal of other parts that I might as well swap the probe at that point. Bosch probes are going for about $130 now.

I'm still scratching my head from 2 posts ago when it was suggested my bank 2 is on driver side, though the N52 engine in this scenario is a straight 6 which, I thought, puts the 2nd bank in the rear for cylinders 4-5-6.
