Crown brake booster pressure sensor failure
Summary of the thread
A 2022 Toyota Crown hybrid owner experienced braking issues, suspecting a brake booster pressure sensor failure, possibly due to incorrect brake system bleeding. The problem manifested as an error message and reduced braking efficiency, requiring more pedal force. A similar case suggested the issue was indeed a faulty sensor, and the solution was to have it professionally diagnosed and replaced, resolving the problem.

Yes, the brake pedal requires considerably more force. How did you resolve the issue?

Based on your description, it does sound like a faulty brake booster pressure sensor issue. I recommend you take your Crown to a reputable workshop for a proper diagnosis. It would be best to have it checked professionally.

Thanks! It was indeed the brake booster pressure sensor, and I had to replace it. The repair cost 90€. Your insights helped a lot.

I also drive a Crown, and I once experienced very similar symptoms. Did the reduced braking feel like you had to apply significantly more pressure to the brake pedal?
