l take place reprogramming the sensor. GM is aware of numerous cases. They will advise once an update is available.
Follow up to the tape. I put the tape on the back half of the sensor all the way across it, works fine.
Update here. I just spoke to the dealership. They called me to follow up. Technician emailed GM directly. GM came back and said that it’s not a sensor part issue, it’s a software issue and GM is working on a update to the system that will take place reprogramming the sensor.

Well, my GUESS is that GM had to source a second sensor part number, which has slightly different output than the original, and they didn't catch it.
One solution is swapping the sensor so it works with the non-updated software.
The other is fix the software to accept the new sensor.
GM figures the former is more costly than the latter.
This, of course, is all conjecture by me, but many have reported that replacing the sensor fixes the issue...
