I Have a Question for Peugeot Experts? Throttle Problem

Hello everyone. After washing my car the other night, it started not using gas and wouldn't go. The rpm is very low, not exceeding 2,500. It only goes 15-20 at most. The car won't open the throttle. When I manually open it, it goes up to 4,000 rpm. When I run the diagnostics, it shows the faults in the image. Is this a throttle body problem or a brain problem? I'll get a throttle body, but if the problem is a brain problem, I'll have to put it in neutral. 206cc442024-01-03 16:33:18
