The P0113 Ford diagnostic trouble code (DTC) is related to a specific issue with the intake air temperature (IAT) sensor circuit in Ford vehicles.
When this code appears, it indicates that the powertrain control module (PCM) has detected a high voltage reading from the IAT sensor or a malfunction within the sensor circuit.
In this article, we will explore the details of the P0113 code, its potential causes, symptoms, and possible solutions.

What is the Intake Air Temperature (IAT) Sensor?
The intake air temperature (IAT) sensor is a crucial component of the engine’s control system in Ford vehicles. Its primary function is to measure the temperature of the incoming air into the engine’s intake manifold.
This information is essential for the PCM to calculate the proper air-fuel mixture and ignition timing, ensuring optimal engine performance and efficiency.
The IAT sensor is typically located in the air intake duct, close to the throttle body. It consists of a thermistor, which changes resistance based on temperature.
As the temperature increases, the resistance decreases, and vice versa. The PCM uses this resistance value to determine the air temperature and make necessary adjustments to the engine’s performance.
Symptoms of P0113 Ford Code
When the P0113 code is triggered, you may experience the following symptoms in your Ford vehicle:
Check Engine Light
The most common symptom is the illumination of the check engine light on the dashboard. This serves as an early warning sign that something is wrong with the IAT sensor circuit.
It is important not to ignore this warning and address the issue promptly to prevent further damage to the engine.
Engine Performance Issues
Since the PCM relies on accurate temperature readings from the IAT sensor, a malfunction can disrupt the engine’s performance. You may notice reduced power, sluggish acceleration, or overall poor engine performance.
This can be particularly noticeable during acceleration or when the engine is under load.
Excessive Fuel Consumption
Incorrect temperature readings can lead to an improper air-fuel mixture, resulting in increased fuel consumption. If you notice a sudden decrease in your vehicle’s fuel efficiency, the P0113 code could be a possible cause.
Monitoring your fuel consumption and addressing this issue can help save on fuel costs in the long run.
It is important to note that while these symptoms are commonly associated with the P0113 code, they can also be indicative of other underlying issues.
Therefore, it is crucial to perform a thorough diagnosis to accurately identify the cause of the problem.
Potential Causes of P0113 Code
Delving into the P0113 code specifically sheds light on the intricacies of the Intake Air Temperature Sensor Circuit.
Yet, recognizing that other models face similar issues emphasizes the universal nature of these challenges, fostering a deeper appreciation for the broader implications of automotive diagnostics.
Several factors can contribute to the occurrence of the P0113 code in Ford vehicles. Some of the common causes include:
Faulty IAT Sensor
The IAT sensor may be faulty, causing it to send incorrect temperature readings to the PCM. This can result in the triggering of the P0113 code.
Over time, the sensor can become contaminated or fail due to normal wear and tear. In some cases, the sensor may need to be replaced to resolve the issue.
Wiring or Connector Issues
Damaged or loose wiring, as well as faulty connectors, can disrupt the signal between the IAT sensor and the PCM. These issues may lead to inaccurate temperature readings and the appearance of the P0113 code.
It is important to inspect the wiring and connectors for any signs of damage or corrosion and repair or replace them as necessary.
Intake Air Temperature Sensor Circuit Short or Open
A short or open circuit within the IAT sensor circuit can cause the PCM to detect a high voltage reading, triggering the P0113 code. This can occur due to damaged wiring, a faulty sensor, or a problem with the PCM itself.
Thoroughly inspecting the circuit and performing necessary tests can help identify the exact cause of the issue.
PCM Malfunction
In rare cases, a malfunction in the PCM itself can be responsible for the P0113 code. However, this is less common compared to other potential causes.
If all other possible causes have been ruled out, it may be necessary to consult a professional mechanic or take your vehicle to an authorized service center for further diagnostics on the PCM.
It is important to note that diagnosing the P0113 code accurately requires proper tools and knowledge. If you are not confident in your abilities, it is advisable to seek professional assistance to avoid any further complications.
How to Diagnose the P0113 Code
Proper diagnosis is crucial to accurately identify the cause of the P0113 code and resolve it effectively. Here are the steps that can help in diagnosing the issue:
Check for Other Codes
Start by using an OBD-II scanner to check for any additional trouble codes present. If there are other codes related to the IAT sensor or the intake system, addressing those first may resolve the P0113 code as well.
This can help ensure a comprehensive diagnosis and avoid overlooking any potential issues.
Inspect Wiring and Connectors
Thoroughly inspect the wiring and connectors associated with the IAT sensor. Look for any signs of damage, corrosion, or loose connections. Repair or replace any faulty components as necessary.
It is important to ensure proper connections and insulation to prevent future issues.
Test the IAT Sensor
Use a multimeter to measure the resistance or voltage output of the IAT sensor. Compare the readings with the specifications provided by the vehicle manufacturer. If the readings are outside the acceptable range, replace the IAT sensor.
It is important to use a compatible sensor that meets the manufacturer’s specifications.
Check for Circuit Short or Open
Test the IAT sensor circuit for any short or open connections. Use a wiring diagram specific to your Ford vehicle to identify the correct wires and perform the necessary tests.
Repair or replace any damaged wiring or connectors. It is important to ensure the circuit is properly functioning to avoid any further issues.
Verify PCM Functionality
If all other potential causes have been ruled out, consider the possibility of a PCM malfunction. Consult a professional mechanic or take your vehicle to an authorized service center to perform further diagnostics on the PCM.
They will have the necessary tools and expertise to accurately assess the PCM’s functionality.
Resolving the P0113 Code
Once the issue causing the P0113 code has been identified, you can take appropriate measures to resolve it. Here are some possible solutions:
Replace the IAT Sensor
If the IAT sensor is found to be faulty, replace it with a new one. Ensure that the replacement sensor is compatible with your Ford vehicle model. It is important to follow the manufacturer’s guidelines and recommendations to ensure proper installation and functionality.
Repair Wiring or Connectors
If any wiring or connectors are damaged or loose, repair or replace them as necessary. Ensure proper connections and insulation to prevent future issues. It is important to use high-quality replacement components to ensure long-term reliability.
Clear Fault Codes
After making the necessary repairs, use an OBD-II scanner to clear the fault codes and reset the PCM. This will turn off the check engine light and allow you to monitor if the P0113 code reoccurs.
It is important to verify that the issue has been resolved before assuming the problem is fully resolved.
Professional Assistance
If you are unsure about diagnosing or resolving the P0113 code, it is advisable to seek professional assistance.
A qualified mechanic with experience in Ford vehicles can provide accurate diagnostics and perform the necessary repairs. They have access to specialized tools and knowledge to effectively resolve the issue.
