Help with p047A code

[4 TUGGIN]

Had exhaust flap replaced at dealer because it was stuck again. Got car back and drove a couple of days and engine light came on again. Scanned it, Has p047A code exhaust pressure sensor B. Sensor that ties in with egr is 03g-906 051A and has 4.8v on top pin, nothing center pin and 5.6v bottom pin. The sensor 076 906 051A that's not wrapped by washer bottle has 4.8v top pin , nothing center pin, 5.6v bottom pin also. Took this one off car and was wanting to test sensor itself. Has no continuity between any pins so I blew into it with air hose slightly and still has none. How can you tell if the sensor is good or bad. Can't read any ohms across any pins either. Also will the car regen. the dpf with this code and faulty sensor. Been driving it for two weeks like this and don't want any issues with the dpf. Any advice here?

Return to the dealer who installed it and inform them that the problem was not fixed.

And how do you know this? If he had a DTC related to the exhaust flap, and they fixed that, and now it has a DTC for a pressure sensor....

If a tail lamp bulb burns out, and you replace it, and next week the headlight bulb burns out, is it the tail lamp bulb installer's fault your headlight failed?
