04 5.4 no factory knock sensors installed?

Hey Guy's, I pulled a po325 code so I purchased one of 2 knock sensors and got a location printout from Ford. It shows them behind the fan pully under the intake.So I removed the airfilter,housing over the intake,altinator and the coolent deal under the altinator, and to my surprise I found the (2) treded screw holes ( bank one and bank two) but no knock sensors had been factory installed. Is this a normal occurance?

Thanks, John

Were the threaded screw holes open or plugged? I would have thought that if the engine was missing knock sensors you would have had codes all along. Are there pig tails there for knock sensors? Not sure what the P0235 code is, but I'm guessing that our engines may not have a knock sensor. If you purchased this vehicle used, maybe previous owner had work done and shop never re-installed them.

The sensors are further back on the block. You have to take the intake off to see them. there are 2 of them. Most common cause of failure I have seen is the wire harness is routed outside of the IMRC rods whenever someone works on it. The wires are supposed to come between the intake and IMRC rods but it's harder to connect them like that.
