Suburban Brake Booster Pressure Sensor Issue
Summary of the thread
The conversation centers around a 2022 Chevrolet Suburban experiencing diminished braking and an error message, potentially due to a faulty brake booster pressure sensor or incorrect brake bleeding. The issue includes a softer brake pedal requiring more travel. A similar past experience suggests it could be related to the ABS system. The recommended solution is to have a qualified workshop perform a thorough diagnostic check, which ultimately confirmed a faulty brake booster pressure sensor as the cause.

Yes, the brake pedal does feel softer and requires more travel than usual. I was planning to replace the brake booster pressure sensor. Was the error consistently present, or did it appear intermittently for you?

Yes, the error was pretty consistent once it started. Given the soft pedal feel you're experiencing, it does sound increasingly like a brake booster or related issue. To be on the safe side, I'd recommend taking it to a qualified workshop for a thorough diagnosis before you start replacing parts. They can check the entire ABS system with proper diagnostic tools.

I appreciate your advice. I will take the vehicle to a workshop for a complete diagnostic check. It turned out to be a faulty brake booster pressure sensor, and the total repair cost, including parts and labor, was 90€. Thank you again for your help.

I had similar symptoms in my Suburban some time ago. Reduced braking power and a dashboard error sounds familiar. In my case, it was related to the ABS system. Did you notice anything unusual about the brake pedal feel, like it being softer or requiring more travel than usual?
