Poor Connection or Damaged Harness: Inspect ECM harness connectors for backed out terminal "B6", improper mating, broken locks, improperly
formed or damaged terminals, poor terminal to wire connection and damaged harness.

the failure is induced, the "MAF" display will abruptly change. This will help to isolate the location of the malfunction.

equivalent.
