Avancier Brake Booster Sensor Error
Summary of the thread
The owner of a 2022 Honda Avancier experienced an error message related to the brake booster pressure sensor and poor braking performance. The issue was suspected to be connected to an incorrect brake bleeding procedure, which can introduce air into the system and affect the sensor. A workshop confirmed this diagnosis, and the problem was resolved by correcting the bleeding process.

Not that I know of. Could an incorrect brake bleeding procedure actually cause this?

That's my suspicion. Incorrect bleeding can introduce air, messing with the booster's sensor. A workshop check is a good idea.

Thank you. I took it to a workshop, and you were correct. The brake system had been bled incorrectly, causing the brake booster pressure sensor to fail. The repair cost 90€.

I had similar symptoms on my Avancier. Has anyone bled the brake system recently?
