What does the intake air temp sensor say?
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. Won’t pass the emissions test.
What does DTC for intake air temp mean?
The second will be an IAT sensor malfunction diagnostic trouble code (DTC) stored in the PCM memory. 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).
How to test the intake air temp ( IAT )?
Testing the intake air temperature (IAT) sensor, which is located inside the mass air flow (MAF) sensor, can easily be done with a scan tool and/or a multimeter.
Where is the IAT sensor on a Jeep Cherokee?
On the Jeep 4.0 engine, the IAT sensor is in the intake manifold behind the throttle body. Right below the tube leading into the engine. The iat sensor is the front sensor on the intake manifold it has a gray 2 wire plug that is the 4.0 lt the 2.5 the sensor is the back sensor on the manifold. It is on the air intake ram prior to the air filter.
This means that the IAT sensor is reporting a temperature of 300 °F (149 °C). P0113: Intake Air Temperature (IAT) Sensor Circuit High Voltage.

Where is the IAT sensor located on the intake manifold?
It ensures optimum combustion and efficient fuel consumption. Where Is the IAT Sensor Located? 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 are the symptoms of bad intake air temp?
Here are some of the specific symptoms you’ll see/have: Diagnostic Trouble Codes: P0112: Intake Air Temperature (IAT) Sensor Circuit Low Voltage. BAD gas mileage. Black smoke coming out of the tailpipe. Won’t pass the emissions test.
How does an intake air temperature sensor work?
Typically, the PCM sends a 5-volt reference to the IAT sensor. The IAT sensor then varies its internal resistance according to air temperature and sends a return signal back to the PCM. The PCM then uses this formation to determine fuel injector control and other outputs.
What is the code for an air temperature sensor?
P1193 is the code for a faulty inlet air temperature sensor, also known as the intake air temperature sensor. It may be possible that there is an issue with the intake air temperature sensor or with the sensor circuit….
How much does it cost to replace an intake temperature sensor?
If your intake temperature sensor is integrated into the MAF sensor, the part cost can increase rapidly. Some MAF sensors cost up to 400$. The replacement of a MAF sensor or intake temperature sensor is often very straightforward and can often be made yourself with basic knowledge.
How can I test my air temperature sensor?
You can test an intake air temperature sensor using a digital Ohm Meter set on the DC volts scale. Turn the IGN switch to the ON position and backprobe the return wire to see the voltage being reported to the PCM/ECM. You can also test the sensor’s resistance, but that’s not as accurate as reading the actual return voltage.
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.
What does a bad air temperature sensor do?
Another symptom of a bad or defective air charge temperature sensor is a noticeable decrease in fuel efficiency. The air charge temperature sensor sends data to the computer, which allows it to make continuous adjustments to the engine’s air / fuel mixture for maximum fuel efficiency.
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.
