DTC P0112 indicates Intake Air Temperature (IAT) sensor is less than self-test minimum of 0.2 volt or 250°F (121°C).

DTC P0113 indicates IAT sensor is more than the self-test maximum of 4.6 volts or -58°F (-50°C).

DTC P0117 indicates Engine Cooling Temperature (ECT) sensor is less than self-test minimum of 0.2 volt or 250°F (121°C).

DTC P0118 indicates ECT sensor is more than self-test maximum of 4.6 volts or -58°F (-50°C).

DTC P0125 indicates ECT sensor has not achieved the required temperature level to enter closed loop operating conditions within a specified amount of time after engine start.

DTC P1112 indicates IAT sensor signal was intermittent during Comprehensive Component Monitor.

DTC P1116 indicates ECT sensor signal is out of self-test range (0.3-3.7 volts).

DTC P1117 indicates ECT circuit was intermittently open or shorted while engine was running.

DTC P1285 indicates an engine overheat condition was sensed by Cylinder Head Temperature (CHT) sensor.

DTC P1288 indicates CHT sensor is out of self-test range (engine not at operating temperature).

DTC P1289 and P1290 indicates CHT sensor circuit malfunction (open or short).

DTC P1299 indicates an engine overheat condition was detected by CHT sensor and a FMEM strategy (fail safe cooling) was activated to cool engine.
