Navara Brake Booster Pressure Sensor Error

I'm experiencing an issue with my 2021 Nissan Navara (gasoline engine). I'm getting an error message in the speedometer, and the braking effect is significantly reduced. Diagnostic tools show an error stored related to the brake booster pressure sensor. The Navara has 128711 km. I suspect an incorrect brake bleeding procedure might be the cause. Has anyone encountered similar problems?

I also own a Navara, and had similar symptoms. Did you recently work on your brake system?

Yes, I replaced the brake lines a few weeks ago. Is the pressure sensor connected with the ABS system, and could it be related to replacement parts? Is this what you experienced?

Indeed, in my case it was an incorrectly bled brake system after replacing a caliper. The error was related to the ABS module reading incorrect pressure from the booster. I would recommend taking it to a workshop to have the system professionally bled and the sensor checked.

Thanks for the confirmation. It was indeed a bleeding issue. A visit to the workshop, a proper brake bleed and a new pressure sensor for 90€ solved the problem. I appreciate your help.
