It’s been like this since I got the car (1 year, 3K), and it had a brake flush right before.

Yes, my car only threw a code (and had limp mode) on track. On the street I just had the annoying pump buzzing a lot with no code. You shouldn't notice the pump operating regularly if the sensor is good and the system is working properly.
