DTC P0112: Intake Air Temperature (IAT) Sensor Circuit Low Input

  1. Connect scan tool to Data Link Connector (DLC). Turn ignition on. Select IAT sensor parameter on scan tool. If scan tool displays 302°F (150°C), go to next step. If scan tool displays near ambient temperature, check for an intermittent problem. See TROUBLE SHOOTING - NO CODES article.
  2. Disconnect IAT sensor harness connector. If scan tool display drops to -40°F (-40°C), replace IAT sensor. If scan tool display is not as specified, check Light Blue wire for a short to ground. Repair as necessary. If wire is okay, replace PCM and retest system.
