WARNING: This page is about a different car, the 2008 Ford Pickup, 2008 Ford F550 Super Duty, 2008 Ford F450 Super Duty, and 2008 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
P0112 - INTAKE AIR TEMPERATURE (IAT) SENSOR 1 CIRCUIT LOW

Description:  The powertrain control module (PCM) monitors the IAT sensor circuit through the comprehensive component monitor (CCM). If the IAT signal voltage is less than the minimum calibrated limit, the test fails.
Possible Causes: 
  • IAT signal circuit short to ground
  • Damaged sensor
  • Incorrect harness connection
Diagnostic Aids:  An IAT PID reading less than 0.15 volt for greater that 50 ms indicates a concern is present.
