MAF Questions???

['95 Pilot]

OK, I am still having problems with my Mass Air set up. I have the C and L on, new 24 # injectors, I know probably too much, new FRP 190 fuel pump, just put on a BBK fuel pres regulator. Ran the codes, Autozone special (Actron code scanner), came up with 157. I also checked the voltage at the MAF 14.3V going to the A and B terminals, .08V (yep double and triple checked it) to the C and D terminals. Can I replace just the electronics from Ford, or do I need to buy an entire MAF from ford the Electronics? This is driving me nuts....
