What P1020 means
Source: SAE J2012 / OBD-IIP1020 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 Volkswagen and its owners have filed about it; the code’s page across every make has the whole file.
