   Chafed or Broken Wiring Harness (Very Common) — This is the most frequent cause on newer GM vehicles. The factory wiring harness to the Mass Airflow (MAF) sensor is too short or secured with an overly tight zip tie. Engine movement causes the LIN bus wire to chafe and break internally near the connector.
