What is the IAT code?
What is the IAT code?
Diagnostic trouble code P0113 stands for “Intake Air Temperature (IAT) Sensor Circuit High Input.” If your OBD-II scanner reports this code, it means your car’s computer has determined that there’s a problem with the IAT sensor 1 or its circuit. A working IAT sensor sends its readings to the PCM.
What is the p0113 code for an air temperature sensor?

What causes a high input code on an IAT sensor?
See the IAT in depth article (P0112) for more background on the IAT sensor. Note: Circuit High Input codes are mostly caused by defective alternators that develop excessive voltages, although there may be other causes as well, such as short circuits that “leak” current into a particular system from other,…
What is the code for the intake air temperature sensor?
Meanwhile, a sensor that produces a low voltage input merits the trouble code P0112. P0098 is the mirror image of P0113 since it reports the same issue of low temperature, higher electrical resistance, and high signal voltage in sensor 2, the second IAT sensor in the engine.
Where is the IAT sensor in the intake manifold?
It can be located on the air cleaner, in the air inlet tube, or in the intake manifold. The IAT sensor is a two-wire sensor with a negative temperature coefficient resistor positioned so that it reads the air entering the engine.

What is the diagnostic code for an IAT sensor?
The fault may lie in other parts of the IAT circuit, such as the connection. If the sensor is faulty, a replacement part can cost anywhere between $1.94 to $110.93 on CarParts.com. There are other diagnostic trouble codes that cover the IAT sensors and their attendant circuitry. For example, an intermittent IAT sensor signal falls under P0114.
Why is the IAT sensor reading too high?
Accurate readings help the engine burn fuel efficiently. When the PCM gets a signal voltage reading above the maximum value, it realizes that the IAT sensor circuit has malfunctioned, either because the sensor is unplugged, the terminals are damaged, one of the sensor wires has been cut, or some other open circuit issue.
