What is PGN and SPN? Can you spell out those acronyms?
PGN is part of the CAN ID used in J1939 which uses 29bit ID's (J1939 is common in agricultural machinery and some trucks). SPN is basically the signal name and can be determined from byte position once you have PGN. Your ID looks more likely to be an 11bit ID and doesn't look like a valid J1939 ID at all.
There are many online tools for extracting the PGN from the ID such as this one: https://michael.chtoen.com/convert-j1939-id-to-pgn.php
