Lexus NX Brake Booster Pressure Sensor Fault

I'm experiencing an issue with my 2015 Lexus NX hybrid (194362 km). An error message appears, and the braking is poor. Error codes related to the brake booster pressure sensor are stored. Could an incorrectly bled brake system cause this?

I had similar symptoms on my NX. Check the brake booster. Is the ABS system acting strangely?

Thanks. What exactly caused your problems? Did the ABS malfunction, and what was the fix?

The ABS seemed to be activating unnecessarily. After investigation, the workshop confirmed the booster pressure sensor was faulty after bleeding the system. Get it checked by a professional.

Thanks; this is helpful. I had the brake booster pressure sensor replaced for 90€. Turns out the brake system was indeed bled incorrectly before.
