  • Diagnostic support note 

  • This is a continuous monitor (CCM).
  • MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
  • FREEZE FRAME DATA is available.
  • The DTC is stored in the PCM memory.
POSSIBLE CAUSE 
  • IAT sensor malfunction
  • Poor connection at MAF/IAT sensor or PCM connector
  • Open circuit in wiring harness between MAF/IAT sensor terminal D and PCM terminal 1AH
  • Short to power supply in wiring harness between MAF/IAT sensor terminal D and PCM terminal 1AH
  • Open circuit in wiring harness between MAF/IAT sensor terminal E and PCM terminal 1AA
  • PCM malfunction
