If you own a Chevy vehicle equipped with an OBD-II (On-Board Diagnostics) system, you may encounter various error codes that indicate potential issues with your vehicle’s performance.
One of these codes is P0113, which specifically relates to a problem with the Intake Air Temperature (IAT) sensor circuit.
In this article, we will delve into the details of the P0113 chevy error code, its possible causes, and provide some troubleshooting tips to help you resolve the issue.
However, the story doesn’t end there; other car brands, also grapple with this same challenge.

What is the P0113 Error Code?
The P0113 error code indicates a malfunction in the Intake Air Temperature (IAT) sensor circuit. The IAT sensor is responsible for measuring the temperature of the air entering the engine.
This information is crucial for the engine control unit (ECU) to determine the appropriate fuel-to-air mixture, ignition timing, and overall performance of the engine.
When the IAT sensor circuit fails to provide accurate readings or there is a problem with the sensor itself, the P0113 error code is triggered.
Possible Causes of the P0113 Chevy Error Code
Faulty IAT Sensor
A defective or damaged IAT sensor can lead to inaccurate temperature readings, triggering the P0113 error code. It is essential to check the sensor’s condition and functionality to ensure it is operating correctly.
Wiring Issues
Problems within the wiring harness that connects the IAT sensor to the ECU can also lead to the P0113 error code. Loose connections, damaged wires, or short circuits can disrupt the signal transmission and cause the error code to appear.
Faulty ECU
In some rare cases, the issue may lie with the engine control unit itself. If the ECU fails to receive accurate data from the IAT sensor or cannot process the information correctly, it may trigger the P0113 error code.
Air Intake Blockages
Restricted or blocked airflow to the IAT sensor can result in inaccurate temperature readings. A clogged air filter or debris in the intake system can disrupt the sensor’s functionality and lead to the error code.
Troubleshooting Tips for the P0113 Error Code
1. Inspect and Test the IAT Sensor
To begin troubleshooting the P0113 error code, you should locate the IAT sensor in your Chevy vehicle. Typically, it is found in the air intake tubing or the intake manifold.
Once you have located the sensor, inspect it for any physical damage or signs of wear. If the sensor appears to be in good condition, you can proceed to test its functionality using a multimeter.
To properly test the IAT sensor, follow these steps:
- Remove the sensor from the intake system.
- Set your multimeter to the resistance or ohms setting.
- Connect the multimeter’s probes to the sensor’s terminals.
- Compare the readings with the specifications provided by the manufacturer.
- If the readings are outside the recommended range, it is likely that the IAT sensor is faulty and needs to be replaced.
2. Check the Wiring and Connections
Another important aspect of troubleshooting the P0113 error code is to examine the wiring harness connected to the IAT sensor and the ECU.
Inspect the wiring for any signs of damage, loose connections, or exposed wires. Ensure that the wiring is securely connected and free from any obstruction.
If you find any damaged wiring, it is advisable to repair or replace the affected sections. If necessary, consult a professional mechanic or refer to the vehicle’s service manual for detailed instructions on wiring repairs.
3. Inspect the Air Intake System
To ensure the proper functioning of the IAT sensor, it is crucial to inspect the air intake system for any blockages or restrictions. Check the air filter for clogs, dirt, or debris, and clean or replace it as needed.
Additionally, make sure that the intake tubing is clear and free from any obstructions that could disrupt the airflow.
4. Reset the Error Code
Once you have addressed the potential causes and performed the necessary repairs or replacements, it is essential to reset the error code.
This can be done using an OBD-II scanner or by disconnecting the vehicle’s battery for a few minutes. By resetting the code, you will be able to determine if the issue has been successfully resolved.
Conclusion
Dealing with the P0113 error code in your Chevy can be frustrating, but armed with the knowledge provided in this article, you can now approach the issue with more confidence.
Remember to thoroughly inspect the IAT sensor, check the wiring and connections, and inspect the air intake system.
By following these troubleshooting tips, you can diagnose and resolve the P0113 error code, ensuring your Chevy vehicle operates optimally once again.
