Looking at the Chilton Manual I see 2 sensor's pictured. I also have 2 sensor's on the motor in front of the Intake Manifold. The pictured sensor's position look nothing like what I see when I look on my motor. I think the problem I'm having is the picture is to much of a close up and I can't see which sensor is which. I have the right manual but......this is my problem. Which one to replace?

97 F-150 4.6L....... Anyone? Thanks.... James
