Peugeot 207 Brake Booster Pressure Sensor Fault

I've got a Peugeot 207 myself, and that sounds pretty familiar. I had similar issues with weak brakes, and the ABS light was on. Did the error code specifically point to the pressure sensor? Because it could also be related to the ABS unit itself.

Yes, the error code specifically indicated a fault with the brake booster pressure sensor. I also checked the ABS system for any errors, but there weren't any. Could it still be related to the ABS unit even if it isn't showing any error codes? Is there something specific I should be looking for, or is it more complicated?

Alright, if the code points directly to the sensor, then it's most likely the culprit. Look, I am not a mechanic, and brakes are serious business. My advice would be to take it to a workshop and have them check the sensor and the brake booster itself. Better safe than sorry when it comes to stopping power!

I took it to a trusted workshop, and they confirmed that the brake booster pressure sensor had failed, likely caused by an incorrect brake bleeding procedure performed previously. They replaced the sensor, and now the braking performance is back to normal, and the error message is gone. The total repair cost was 90€; your advice pointed me in the right direction.
