2000 Impala 3.4 PCM wiring

I have been chasing a P0102 code that points to the MAF sensor. I replaced the unit, then did further troubleshooting. Found out that am getting a reading of 1.9 g/s from the PCM, even when the MAF is not connected, so I figure I have a wiring problem. I have voltage on the red and black but nothing on the yellow. Anyone have a wiring diagram that I could use to trace the wires all the way back to the PCM? Thanks for your help!
