Hello everyone,
Today I did a check on my 2012 Corolla and found an active Startability Malfunction - P1604. It is really weird, as there are no lights on, check engine or similar, and the car starts and drives excellent. Spark plugs were replaced 3 months ago with tested Iridium Denso, battery of the car changed last year. I'm thinking also to change the ignition coils or at least clean them with a contact cleaner, as the car is almost 250 000 km, but I'm not convinced that ignition coils are the problem. I ran a live diagnostics, no misfire or similar.
Last oil change with new air and oil filter was also done 3 months ago.
Any thoughts over below data or is just another silly code?

Clear the code and see if it comes back or not.
Hello everyone,
I read and followed your instruction. Nothing with the fuel pump so far, erased the error and it didn't turn back.
However, per documentation, I understand that this error might happen when I'm running out of fuel or when the fuel quality is low. I remember that last month I ran only with fuel reserve for dozens of kilometers until I found a gas station on the highway, that might be the cause.
So it looks like everything is fine now, attaching the last scan report with more data. If you're seeing something wrong just let me know, but I believe everything is fine with below data:
