Since you have replaced the MAF, it shouldn't be dirty or failed, but I would clean it anyway with MAF cleaner. I would also take apart the connection and blow out both sides with air and reconnect. If those things don't change anything, I would use the info Miguelcon74 gave you to trace out the wiring.
Potential causes for this trouble code, P0102, may include:
Dirty or contaminated mass air flow sensor
Failed MAF sensor
Intake air leaks MAF sensor electrical harness or wiring problem (open, shorted, frayed, poor connection, etc.)
Note that other codes may be present if you have a P0102. You may have misfire codes or O2 sensor codes, so it's important to take a "big picture" look at how the systems work together and effect each other when doing a diagnosis.
