The P0113 Dodge error code in Dodge vehicles is related to the Intake Air Temperature (IAT) sensor circuit. This sensor plays a crucial role in measuring the temperature of the air entering the engine.
When the IAT sensor circuit malfunctions, it can lead to various performance issues and trigger the P0113 error code.
In this article, we will delve deeper into the causes, symptoms, and possible solutions for the P0113 error code in Dodge vehicles.

Understanding the P0113 Error Code
The P0113 error code is specific to Dodge vehicles and is often accompanied by the check engine light illuminating on the dashboard. It indicates that the IAT sensor circuit is providing a high voltage signal to the Engine Control Module (ECM) or Powertrain Control Module (PCM).
This high voltage signal can be caused by various factors, including faulty wiring, a malfunctioning sensor, or issues with the ECM/PCM.
Common Causes of the P0113 Dodge Error Code
Several factors can contribute to the occurrence of the P0113 error code in Dodge vehicles. It’s important to understand these causes in order to effectively diagnose and resolve the issue. Here are the common causes to consider:
Faulty IAT Sensor
A defective or malfunctioning IAT sensor can cause incorrect temperature readings, leading to the triggering of the P0113 error code. This can happen due to sensor wear and tear, electrical problems, or sensor contamination.
IAT Sensor Wiring Issues

Damaged or loose wiring connections between the IAT sensor and the ECM/PCM can disrupt the proper signal transmission, resulting in the P0113 error code. It’s important to carefully inspect the wiring harness for any signs of damage, corrosion, or loose connections.
Faulty ECM/PCM
In some cases, a malfunctioning ECM/PCM can mistakenly interpret the IAT sensor’s signals, leading to the P0113 error code. This can happen due to software glitches, electrical issues, or component failure.
If all other potential causes have been ruled out, it may be necessary to have the ECM/PCM inspected or reprogrammed by a professional.
Air Intake Blockage
A blocked air intake system can affect the accuracy of the IAT sensor’s readings, causing the P0113 error code to appear. It’s important to ensure that the air intake system is free from any blockages or obstructions.
Regularly inspect and clean the air filter and other components to maintain proper airflow.
Symptoms of the P0113 Error Code
When the P0113 error code is present in a Dodge vehicle, you may experience a range of symptoms that can indicate the presence of this issue. Here are the common symptoms to look out for:
Check Engine Light
The most common symptom is the illumination of the check engine light on the vehicle’s dashboard. This serves as an indicator that there is a problem with the IAT sensor circuit.
Loss of Power
The engine may lose power or experience a decrease in performance. This can manifest as a lack of acceleration, reduced top speed, or overall sluggishness.
Hard Starting
You may encounter difficulties starting the engine, especially when the car is cold. This can be attributed to incorrect temperature readings from the IAT sensor, leading to improper fuel-air mixture and combustion.
Poor Fuel Efficiency

The P0113 error code can also result in reduced fuel efficiency, leading to increased fuel consumption. This happens when the engine is not receiving accurate temperature data, causing it to operate less efficiently.
Rough Idle
The engine may idle roughly or experience fluctuating RPMs. This can be a result of improper fuel-air mixture due to incorrect temperature readings from the IAT sensor.
Resolving the P0113 Error Code
To address the P0113 error code in Dodge vehicles, there are several potential solutions to consider. Here are the steps you can take to diagnose and resolve the issue:
Check IAT Sensor Wiring
Start by inspecting the IAT sensor’s wiring harness for any signs of damage, loose connections, or corrosion. Repair or replace any faulty wiring as necessary.
Ensure that the wiring connections are secure and properly connected to the ECM/PCM.
Test the IAT Sensor
Use a multimeter to test the IAT sensor’s resistance and voltage readings. Compare the measured values with the manufacturer’s specified range. If the values are out of range, consider replacing the sensor.
It’s important to use an OEM or high-quality replacement sensor for accurate temperature readings.
Clean the Air Intake System
Ensure that the air intake system is free from any blockages or obstructions. Clean the air filter and other components if necessary. This will help maintain proper airflow and prevent inaccurate temperature readings from the IAT sensor.
Inspect the ECM/PCM
If all other potential causes have been ruled out, it may be necessary to have the ECM/PCM inspected or reprogrammed by a professional. They have the necessary diagnostic tools and expertise to identify any software or hardware issues with the ECM/PCM.
Conclusion
The P0113 error code in Dodge vehicles relates to an issue with the Intake Air Temperature (IAT) sensor circuit. It is crucial to address this error code promptly to ensure optimal engine performance and fuel efficiency.
By understanding the common causes, symptoms, and potential solutions discussed in this article, you can take the necessary steps to diagnose and resolve the P0113 error code in your Dodge vehicle.
If you are unsure or uncomfortable performing the diagnostics and repairs yourself, it is always recommended to consult a certified mechanic or authorized Dodge service center for assistance.
By exploring how the Intake Air Temperature Sensor Circuit operates across different vehicles, like Audi, you gain valuable insights into the shared nuances of this automotive challenge.
