The P0113 Hyundai code in vehicles refers to a problem with the Intake Air Temperature (IAT) sensor circuit.
This sensor plays a crucial role in the operation of the engine, as it provides the engine control module (ECM) with important information about the temperature of the incoming air.
In this article, we will delve into the causes, symptoms, and solutions for the P0113 code in Hyundai vehicles.

What Does the P0113 Code Mean?
When the ECM detects a fault in the IAT sensor circuit, it triggers the P0113 code and illuminates the Check Engine Light on the dashboard.
This code specifically points to a high voltage output from the sensor, indicating that the temperature reading is out of range.
The ECM relies on this sensor data to adjust fuel delivery and ignition timing, so an inaccurate reading can result in poor engine performance and efficiency. If the temperature reading is too high, the ECM may deliver too much fuel, causing the engine to run rich.
On the other hand, if the temperature reading is too low, the ECM may not provide enough fuel, resulting in a lean condition. Both scenarios can lead to issues such as decreased power, rough idle, and hesitation during acceleration.
Common Causes of the P0113 Hyundai Code
Several factors can contribute to the triggering of the P0113 code in Hyundai vehicles. These include:
Faulty IAT Sensor
The IAT sensor itself may malfunction, providing inaccurate temperature readings or no readings at all. This can occur due to sensor damage, wiring issues, or internal component failure.
If the sensor is damaged or its internal components fail, it may not be able to accurately measure the temperature of the incoming air, leading to incorrect readings and the triggering of the P0113 code.
IAT Sensor Circuit Issues
Problems within the wiring harness can disrupt the signal between the sensor and the ECM, leading to the P0113 code. Loose connections, damaged wires, or corrosion can all interfere with the proper transmission of the sensor data.
It is important to inspect the wiring harness for any signs of damage or corrosion and ensure that all connections are secure.
Intake Air Temperature Sensor Placement
If the IAT sensor is installed improperly, it may not be able to accurately measure the temperature of the incoming air. This can result in incorrect readings and trigger the P0113 code.
It is crucial to ensure that the sensor is correctly positioned and securely fastened to the intake manifold or air intake tube.
Common Symptoms of the P0113 Code
When the P0113 code is present in a Hyundai vehicle, certain symptoms may arise. These symptoms can vary in severity, but it is essential to address them promptly to prevent further damage. Some common symptoms include:
Check Engine Light
The most obvious and initial indicator of the P0113 code is the illumination of the Check Engine Light on the dashboard. It serves as a warning that something is wrong with the IAT sensor or its circuit.
It is important not to ignore this warning, as it can indicate potential issues with engine performance and fuel efficiency.
Poor Engine Performance
Inaccurate temperature readings can lead to incorrect fuel delivery and ignition timing. This can result in decreased engine performance, including reduced power, rough idle, and hesitation during acceleration.
If you notice that your vehicle is not running as smoothly as usual or lacks power, it is important to address the P0113 code promptly.
Decreased Fuel Efficiency
A malfunctioning IAT sensor can disrupt the air-fuel mixture, leading to decreased fuel efficiency. This means you may notice a drop in your vehicle’s MPG (miles per gallon) rating.
If you find that you are filling up more frequently or getting fewer miles per gallon than usual, it is important to investigate the P0113 code as a potential cause.
Diagnosing the P0113 Code
Recognizing that Audi models also contend with this challenge reinforces the importance of comprehending how common issues transcend specific car brands.
To diagnose the P0113 code in a Hyundai vehicle, it is essential to follow a systematic approach. Here are the steps typically taken to identify the root cause of the issue:
Scan the ECM
Using an OBD-II scanner, retrieve the trouble codes stored in the ECM. This will include the P0113 code, along with any accompanying codes that may provide additional insights into the problem.
By scanning the ECM, you can gather valuable information about the specific issue affecting the IAT sensor circuit.
Inspect the IAT Sensor and Wiring
Visually inspect the IAT sensor and its wiring harness for any signs of damage, loose connections, or corrosion. Ensure that the sensor is correctly positioned and securely fastened.
Any visible issues with the sensor or wiring should be addressed before proceeding with further diagnostics.
Check for Voltage Output
Using a multimeter, measure the voltage output of the IAT sensor. Compare the readings to the manufacturer’s specifications to determine if it is within the acceptable range.
If the voltage output is too high or too low, it indicates a problem with the IAT sensor and further investigation is needed.
Test the IAT Sensor Resistance
Measure the sensor’s resistance using an ohmmeter. Again, compare the readings to the specified values provided by the manufacturer. If the resistance reading is outside the expected range, it suggests a faulty IAT sensor that needs to be replaced.
Test the Wiring and Connections
Perform a continuity test on the wiring and connections to ensure there are no open circuits or short circuits. A continuity test helps identify any breaks or faults in the wiring that may be causing the P0113 code.
If any issues are found, the affected wiring or connections should be repaired or replaced.
Fixing the P0113 Code
Once the cause of the P0113 code has been identified, appropriate measures need to be taken to rectify the issue. The following solutions can help resolve the problem:
Replace the IAT Sensor
If the sensor is determined to be faulty, it should be replaced with a new, genuine Hyundai part. Ensure that the new sensor is installed correctly and connected securely.
Proper installation is crucial to ensure accurate temperature readings and prevent the recurrence of the P0113 code.
Repair or Replace Wiring
Address any wiring issues, such as loose connections, damaged wires, or corrosion. Repair or replace affected wiring harnesses as necessary to restore proper circuit functioning. It is important to use high-quality wiring and connectors to ensure reliable and long-lasting repairs.
Clear the Trouble Codes
After the repair has been completed, use an OBD-II scanner to clear the trouble codes from the ECM. This will reset the Check Engine Light and allow you to monitor the system for any further issues.
Clearing the trouble codes is an important step to ensure that the repair was successful and that the P0113 code does not reappear.
Test Drive
Take the vehicle for a test drive to ensure that the Check Engine Light remains off and that the symptoms associated with the P0113 code no longer persist. This step will help confirm the successful resolution of the problem.
Pay attention to the engine performance and fuel efficiency during the test drive to ensure that they have improved after the repairs.
Conclusion
The P0113 code in Hyundai vehicles indicates a problem with the Intake Air Temperature (IAT) sensor circuit. Addressing this issue promptly is crucial to prevent potential engine performance problems and reduced fuel efficiency.
