Odyssey Brake Errors
Summary of the thread
A 2023 Honda Odyssey hybrid displayed error messages on the speedometer and experienced weak braking at 99,599 km. The issue was suspected to be related to the brake booster pressure sensor, potentially caused by incorrect bleeding of the brake system, which could trap air and affect sensor readings. The problem was resolved by replacing the pressure sensor, confirming the initial diagnosis.

Bled incorrectly, you say? What exactly happens if it's bled badly?

Yeah, if air gets trapped in the system, especially near the pressure sensor, it can throw off the readings and cause the issues you're seeing. I'd wager that's your culprit. I'd still take it to a workshop. That's usually the pressure sensor which can lead to reduced vehicle safety!

Thanks, man. You were spot on. Turns out the brake system bleeding was indeed the issue. Got the pressure sensor replaced. Cost me 90€ Appreciate the help!

Weak braking and a dash error on a new hybrid Odyssey? Sounds like the brake booster pressure sensor is toast. Was the brake system recently bled? If so, it might have been done incorrectly. These newfangled hydraulic brakes are a pain if you're not careful. I've seen similar stuff before on other cars.
