code 31, need more suggestions

hey guys, i've been trying to track down the 31 code. i've picked up a manual and have done some tests with the multi meter. i'm getting 4.6 volts on my harness side for my sensor (its supposed to be around 5 the book says), and the sensor is brand new so i'm assuming that it is good. however i'm still getting the 31 code. whats next to check? the erg valve itself seems to be good (its not even 6 months old and i have cleaned it since). help, whats next?
