P0341 CMP Sensor Circuit Performance
This was the only DTC that was thrown on my truck. Lately I have seen a 2-2.3 mpg decrease in fuel efficiency so I was curious if any codes showed anything.

From the 6.0 bible:
Camshaft position sensor code--cmp signal intermittent--poor connection,defective sensor, electrical noise.
I'd check for a harness issue also. Does it have an excessivly long crank to start time?

Another question the "electrical noise" - you have a example of a particular sound incurred with this?

I was quoting from the 6.0 bible, but I believe electrical noise to a computer would be similar to static you might hear in a pair of earphones. In other words, the computer isn't hearing what the sensor is saying either due to a bad connection or a bad sensor. I'm no electrical expert--LOL--but I'd clean the connection, clear the code, and see if the DTC returns before replacing the sensor. I haven't even heard of a CMP sensor going bad on a 6.0 yet, although they are very common on the 7.3's.
