1997 Chevrolet 2500 Pickup Question: MIL code of P0102

I am continuing to pop a MIL code of P0102 for MAF sensor low voltage. Performed all voltage and operational checks listed in guide book and everything works as advertized. Replaced MAF sensor twice, but continue to get the code.

What else should I be checking?
