Codes 335, 336 & 337....ideas?

I have a CEL on my truck that comes on few a couple minutes, then goes off for a few minutes and continues.

I scanned her today and got three codes, 335, 336, and 337.

335 = EGR sensor circuit voltage higher or lower then expected.
336 = EGR sensor circuit voltage higher then expected.
337 = EGR sensor circuit above maximum voltage.

any ideas what i could look for and where?

i'm clueless.........
