02 V70XC P0340 code

Hello all,
I have 2002 V70XC 2.5T. I just got done replacing the head gasket and the timing belt on my car. I have the P0340 code coming up now. The car runs and drives, but rough. This didn't start until after running the car and driving it about 10 miles. I got another sensor from the junk yard to see if that would help, but no change, which it could be another bad sensor. I checked continuity between the sensor connector and the pins at the ECU and they are at 0 ohms. With key on, sensor unplugged I'm getting 4.9V on pin 1 and 3, and no voltage on pin 2. Not sure what's going on or where to go from here, any help is much appreciated!
