camshaft

Hello,
I have a problem with the Kia Picanto camshaft sensor
has three pin one mass, 12v and supposedly because I get the dough by the black 12v by the brown and another 12V for the green that being in contact and started

failure P0340
a help I do not understand why the signal would not have 12v input is an
exit signal not?

Hello, the camshaft sensor are hall effect if they feed on 12V from the other, it is the mass of the medium. The signal to measure it must measure with a frequency tester or with a logic tip. What failure does the vehicle make you does not start?
