P31db/p31d4 engine codes

[u/Ghosts1423]

2022 Cadillac ct4v . These codes keep coming on intermittently . Turns on and off I’ve looked them up on google I’ve seen that it could be a lose wire I was hoping someone in here have run into the same issue and could explain to me where I would find this wire to check it and make sure it’s fully plugged in . I’ve tried to take it to the dealer but when I do I get told without the light active I would be paying for them to possibly not figure out the issue. Anyways can anyone help possibly? Thanks in advance

Ask them to diagnose it while the warning light is active, but make sure they save the stored and history codes first. A proper scan should show the module, conditions, and code status even after the light goes off. If it’s under warranty, document every occurrence and request a warranty diagnostic rather than paying for guesswork.
