      A:

      Hi Don, there are actually 4 oxygen sensors on your 2005 FORD F-150 4.6 L. They are normally numbered something like "Bank 1 Sensor 1" Bank 1 is on the passenger side; Bank 2 is on the driver's side. Sensor 1 is the upstream sensor (near the frame, between the block and the cat) and Sensor 2 is near the Y-pipe (downstream of the cat).
