Have p2305, camshaft sensor code.Changed coil and wires but problem is there, what can I do?

Question

I changed the o'ring on the camshaft position sensor and the respective code disapear.
When I starting on the minivan, only works cilinders 1 and 4 because I don't have electrical current on cilinders 2 and 3.
I replaced ASD relay, ignition coil and wires and the problem doesn't finish.What else can I do?

Answer 1

P2305 Ignition coil # 2 secondary circuit insufficient ionization

This lead you with the ECM, if 2 and 3 clyinder is not firing the ECM is faulty.
