It is a documented one: NHTSA's files hold 12 manufacturer filings and 1 owner report naming P2002 on 6 Ram model years (2017–2020). Whether it is a problem on one particular car is a diagnosis, not a count — but a bulletin that names the code on your model year is the place to start.

2019 3500 (4 documents), 2018 2500 (2 documents), 2017 2500 (2 documents).
Does P2002 on a Ram mean it is recalled?
No. Recalls are filed by campaign and matched by VIN; no recall is triggered by a scan tool. Check the VIN at nhtsa.gov/recalls, or open the model year's page here for the campaigns filed against it.
