What should the intake air temp be?
P0112: Intake Air Temperature (IAT) Sensor Circuit Low Voltage. This means that the IAT sensor is reporting a temperature of 300 °F (149 °C). P0113: Intake Air Temperature (IAT) Sensor Circuit High Voltage. This means that the IAT sensor is reporting a temperature of -38 °F (-39 °C). Bad gas mileage. Black smoke coming out of the tailpipe.
What are the symptoms of an intake air temp sensor?
Here are some of the specific symptoms you’ll see/have: P0112: Intake Air Temperature (IAT) Sensor Circuit Low Voltage. This means that the IAT sensor is reporting a temperature of 300 °F (149 °C). P0113: Intake Air Temperature (IAT) Sensor Circuit High Voltage. This means that the IAT sensor is reporting a temperature of -38 °F (-39 °C).
How to fix a bad intake air temperature ( IAT )?
If this does not happen, it means that the internal computer is to blame, and that it is not producing the voltage that the IAT sensor needs to function. To fix a faulty intake air temperature sensor, remove all carbon and oil accumulation. If this does not fix the problem, replacing the unit is the best option. Like it? Share it!
Where is the temperature sensor on the intake manifold?
The Intake Air Temperature Sensor is located somewhere on your intake pipes between the air filter and the intake manifold. It is often integrated with the MAF Sensor . Often, it is also installed on the intake manifold .
What is “normal” intake air temperature?
The normal temp range for the C12 is between 120 and 140 degrees F. The higher the load on the engine and the higher the ambient temp. The higher the intake air will be. The max allowable is 150 degrees F. Normal causes of high intake air temp are: Restricted air to air cooler.
What should air intake temp be?
Maximum allowable air temperature rise over ambient at intake manifold 16.7 C [30 ºF] Intake Manifold Air Temperature Warning Limit 74ºC [165ºF] Intake Manifold Air Temperature Shutdown limit 76.7ºC [170ºF] Diesel engines are best suited for air temperatures between 60 and 90°F [15 and 32°C].
What are the symptoms of a bad intake air temperature sensor?
Another symptom of a bad or defective air charge temperature sensor is difficulty starting in cold conditions. The air charge temperature sensor sends a signal to the computer during cold conditions that allow the computer to provide additional fuel required during cold starts.
What does the intake air temperature sensor do?
The air charge temperature sensor, also referred to as the intake air temperature sensor, works to monitor the temperature of the air as it enters your car engine. The engine’s computer has to have this information so it can determine how to balance the mixture of air and fuel.
P0113: Intake Air Temperature (IAT) Sensor Circuit High Voltage. When your scan tool reports this DTC, the IAT sensor is reporting a temperature of -38 °F (-39 °C). Bad gas mileage.

What causes a bad intake air temperature ( IAT ) sensor?
The above symptoms of a bad intake air temperature (IAT) sensor are not a foolproof way of determining the problem, because they are common for a few other malfunctioning components as well, such as mass air flow sensor, oxygen sensors, coolant temperature sensor, etc.
How much does an intake air temperature sensor cost?
On many late model vehicles the sensor is built in to the mass air flow sensor. That being said, they can reach almost $200 for a factory part. It’s best to test the sensor and verify it’s no longer working correctly.
The Intake Air Temperature Sensor is located somewhere on your intake pipes between the air filter and the intake manifold. It is often integrated with the MAF Sensor . Often, it is also installed on the intake manifold .
What to do if your intake temperature is 300°F?
If the temperature reading displays -30 to -40°F, the dashboard light should show the code P0113, and if the reading displays 300°F, the dashboard should show the code P0112. If the reading shows a temperature of 300°F, you need to check if the MAF sensor wires are shorted because of the internal copper getting exposed to each other.
