What P1DD2 means

Source: SAE J2012 / OBD-II

P1DD2 is a manufacturer-specific code: the second character is a 1, which under the OBD-II standard hands the definition to whoever built the vehicle. The same code can mean one thing on a Ford and something unrelated on a Hyundai. Any site that prints a single definition for it is guessing.

A stored code names the test that failed, never the part that caused it. The record above is what Jeep and its owners have filed about it; the code’s page across every make has the whole file.

Common questions

Source: NHTSA files and the OBD-II standard

Is P1DD2 a known problem on Jeep vehicles?

It is a documented one: NHTSA's files hold 12 manufacturer filings and 6 owner reports naming P1DD2 on 5 Jeep 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.

Which Jeep models does P1DD2 appear on most?

2018 Compass (10 documents), 2017 Renegade (5 documents), 2020 Compass (1 document).

Does P1DD2 on a Jeep 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.
