The MAF (Mass Air Flow) sensor is a very common problem with these along with the pickups. This isn't what you would call an inexpensive part. Definitely do some shopping before you buy one.

location is under the hood where the aircleaner is there is an electrical connection that plugs into the mass air flow sensor

if you put it in with the wire harness that plugs into the trucks harness you have to make sure the amp turn on wire is connected from the radio to the harness if the amp isnt on you get no sound, if you didnt buy the harness and cut into the trucks wires you could have a problem, check all radio and amp fuses also

Check the wire leads and clean them before reconnecting the wire leads. It wouldn't hurt also to clean the MAF sensor with MAF cleaner, the code your getting is most common to the high performance oil base filters like K&N.
Good luck and this should help you resolve your MAF issues. Thank you for using Fixya
