Code PO104 saying MAF sensor.Where is that sensor at exactly

Tried Ram forums where owners may be more helpful? I use rockauto for parts lookup and don't see maf sensors listed. Map sensor yes. Maf sensor no. Virtually all mass air flow (maf) sensors reside in a round air intake housing between air filler and throttle body. The maf sensor itself is mounted into the housing with a multiple pin connector protruding from it. Be sure the intake air assembly connected to throttle body doesn't have an air leak between maf sensor and throttle body. All airflow must go thru the maf sensor to detect airflow volume for the EFI system.
