Peugeot 307 SW Stuck in Automatic Gear P

Hello; My vehicle is 2004 model Peugeot 307 SW. There was nothing in my vehicle. I stopped. I landed and took care of my business for 5 minutes. I came, the gear is stuck in P. When I opened the door of the vehicle, there was a squealing sound three times. PUT when I look at the console screen. AUTO. TRANSMISS. There is a LEVER IN POSITION P warning. Also, when I turn on the first ignition on the left gear display panel of the vehicle, it reads (-, *, S) for 1 second and then P. Normally, when I press the brake, the automatic gear would drop itself into neutral with the click of a button. He's not doing that right now. This is because of the brake sensor or is there another situation? The car is not running.

Doesn't he know the reason?

In this case, the first thing you need to look at is the brake switch that you need to look at when the click sound comes when you press the brake, if not, remove the battery and remove the battery and then plug it in the socket. I solved it like this. I put it back on, that's how it went

Exactly I washed the car. Now I'll go try what you say
