Fault code 103...what is it!?

[Heartwork]

just self diagnosed my car and fault code 103 is what it looks like that is throwing off my check engine light.....
the service manual says its a "Parking/Netural Switch" wtf is that?!?!?! its on when im driving too, so i dont assume its just when im parked...

My car is a manual and no the parking brake light is not on....
