POSSIBLE CAUSE 
  • Connector or terminal malfunction
  • Open circuit wiring harness between MAF sensor terminal A and main relay No.1 terminal D
  • Open circuit wiring harness between MAF sensor terminal C and PCM terminal 1AJ
  • Open circuit wiring harness between MAF sensor terminal D and PCM terminal 1AN
  • Open circuit wiring harness between MAF sensor terminal B and body ground
  • Short to ground circuit between MAF sensor terminal D and PCM terminal 1AN
  • Intake air leak (near the MAF sensor)
  • A closed throttle indication
