B2s2 no activity

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. I am assuming you have a valid diagnostic tool of high quality able to monitor sensor activity in real time. What are you measuring? Do you have a diagnostic trouble code set that you are troubleshooting? I just question the validity of the test performed and the reasoning - more than the thought that the sensor has no activity. Share more information so we can try to help.
