Just got a used set of tire pressure sensors ...
The little pin inside that you push to let out air, should it be made into the sensors? The ones mounted in my stock 19s seem to have that little pin in there ...
Where does one get that little pin?
If it's missing, are the sensors broken? O_o
Thanks!

 

the sensors aren't based off the pressure against the valves there is a lil whole in the corner don't block that,

some tech specs
