I'd start by checking ref voltage--ground--signal at the sensor. Any applicable trouble codes? What makes you think there is a problem with cam sensor?

When I changed the distributor I forgot to plug in the electrical plug going to the distributor.My car started with a miss. Then remembering I did'nt plug it,I then pluged it in,and ther ws no difference in the way it ran,it still missed.

Terminal c should be 12 volts, key on.
Terminal A is ground.
Terminal B is signal, dc pulse, on and off.

The po341 is for your cam sensor. Was the vehicle missing, before you worked on the distributor?

The po200, says the computer didn't see correct voltage on command line. The command line is a ground. You could have an injector issue?
