supplies 5 V to the IAT signal circuit, and a ground for the IAT low reference circuit.

Conditions for Running the DTC

P0112

* The engine run time is greater than 1 s.

* The DTC runs continuously when the above conditions are met.

P0113

* The engine run time is greater than 1 s.

* The DTC runs continuously when the above conditions are met.

P0114

* The ignition is ON or the engine is running.

* This DTC runs continuously within the enabling conditions.

Conditions for Setting the DTC

P0112

The ECM detects that the IAT sensor signal is warmer than 149掳C (300掳F) for greater than 7 s.

P0113

The ECM detects that the IAT sensor signal is colder than -60掳C (-76掳F) for greater than 7 s.

P0114

The ECM detects that the IAT sensor signal is intermittent or has abruptly changed for greater than 4 s.

Action Taken When the DTC Sets

* DTCs P0112, P0113, and P0114 are Type B DTCs.

* The ECM commands the cooling fans ON.

Conditions for Clearing the DTC

DTCs P0112, P0113, and P0114 are Type B DTCs.

Diagnostic Aids

* Depending on the ambient temperature, an IAT sensor signal circuit or low reference circuit that is shorted to the MAF sensor signal circuit

can cause a DTC P0113 and/or P0114 to set. This condition causes a rapid fluctuation in the IAT Sensor parameter.

* An IAT sensor signal circuit that is shorted to the MAF sensor ignition circuit can cause a DTC P0113 and/or P0114 to set.

* A MAF sensor ground circuit that is open will cause a DTC P0113 and/or a DTC P0114 to set.
