2004 Ford F-150 computer code

Engine Mechanical problem
2004 Ford F150 V8 Four Wheel Drive Automatic

Vin 5 engine-3ov- 5.4 liter
The code indicates that cam sensor A on cam 2 is defective.
Which side is cam 2 and is the cam sensor ithat comes up thru the valve cover sensor A?
The timing cover for the right side is out farther than the left if this helps

Replacing the cam sensor did not fix the problem. Need to know wiring test procedure and wiring pin numbers and sensor wire location in the plug that goes into the computer.
Thanks
