EX200-3 pump control

Hey guys, im running out of ideas my pump is stuck on minimum swash angle so everythings moving super slow. Ive replaced the sloinoid valves with some second hand ones and it made no difference. Also the engine speed sensor. When i unplug both the solinoid valves it it goes to maximum swash and i checked the angle sensor and it reads 4.4v. If i unplug only the angle sensor then nothing happens but from previous experience, it should send it to maximum. That makes me think its not the angle...
