Here is the Removal/Install for the Turbocharger. 1st page in the image shows the location of the B19/11 Temperature Sensor upstream of turbocharger that you are looking for. Appears to be located on the back lower side of the turbocharger. Looks like it's quite a bit of work to get to but the part may need replacement.

Might be a trip to the dealer and perhaps might be something covered under the AEM Field measure but you would need to confirm with the dealer.

Hope this helps

Thank you. I don’t see that sensor on field measure warrant. I wonder if it’s covered.
