CHR Brake Booster Pressure Sensor Failure

My 2016 Toyota CHR hybrid is throwing a curveball. 56k kilometers. I'm getting an error message on the speedometer, braking feels weak, and the error memory is showing a brake booster pressure sensor failure. I suspect it's because the brake system might have been bled the wrong way. Anyone seen this before?

Sounds plausible. Incorrect bleeding can definitely mess with the ABS system and pressure readings. It's like trying to run a marathon with your shoelaces tied together. Was any work done on the brakes recently?

Yeah, the system was bled recently. So, you're saying that the pressure sensor can directly malfunction because of that? What are the chances it's just a faulty sensor?

It's possible it's just the sensor, but improper bleeding is a classic cause. Think of it like this: the air messes with the hydraulic pressure like sand in an hourglass. Either way, needs a proper diagnosis. I would go to a workshop.

Cheers. Ended up going to a shop. Turns out the pressure sensor was indeed faulty because of the brake bleeding issue. A new sensor and a proper bleed fixed it. Total cost 90€. Thanks for pointing me in the right direction.
