How to fix P0113 code: “Intake Air Temperature (IAT) Circuit High Input”

How to fix P0113 code: “Intake Air Temperature (IAT) Circuit High Input”

If you're searching for how to fix the P0113 code, you first need to confirm that the error exists using an OBDII scanner. Then, you can either check the AIT sensor or the air filter. If none of these checks resolved the problem, you need to take your vehicle to the nearest repair shop to get rid of the problem permanently. 

Auto Repairs Are EXPENSIVE


Error codes are very common in any vehicle, and during the lifetime of your car, you will be dealing with one of them at least one time. The P0113 code is one of the common errors your vehicle will throw in the form of a check engine light illuminating.

This code is most likely related to an issue with the intake air temperature circuit. As a driver, you need to be prepared to deal with this code when it happens and how to detect it. 

This article provides you with all you need to know to understand the P0113 code by highlighting its definition, main causes and symptoms, and an expected rough estimate of repair costs. 

What is the P0113 code definition?

According to experts, the P0113 code definition is “Intake Air Temperature (IAT) Circuit Hight Input.” While this definition might make some sense to some drivers, it can be challenging for other drivers to understand the cause of the problem and why this code is triggered.

That's why we recommend that you go through the basics of they can take care temperature circuits that we will highlight briefly in the following sections. Once you understand how this circuit works, you can better understand how complicated and serious this error code is. 

What does the P0113 code basically mean? 

To understand the P0113 code, you must know the purpose of the intake air temperature circuit sensor. This sensor is responsible for sending a signal to the vehicle's internal computer, indicating the intake manifold's temperature.

This piece of information is very important because it goes directly into the timing of the ignition, the air-fuel mixture ratio determination, and other important elements in the combustion system.

 

When the vehicle's internal computer notices that the intake air temperature sensor is not changing and, at the same time, the coolant temperature voltage is going up or down, it won't throw a P0113 code. 

What are the primary causes for the P0113 code?

When your check engine light indicates a P0113 code, the problem is most likely related to one of the following causes:

  • Internal problems in the intake air temperature sensor number one
  • Issues with damaged wiring in the IAT circuit
  • Problems with the PCM, which in most scenarios requires a software update
  • Problems with the connections between the IAT sensor circuits due to dirt or debris 

How do I know if it’s the P0113 code? Symptoms of the P0113 code

When the vehicle has a problem related to the P0113 code, you will notice one of the following symptoms:

Keep in mind that all these symptoms can be linked to various other issues, and therefore, you cannot simply say that when the check engine light illuminates, it's linked to its AP0113 code.

Unless you confirm using an OBDII scanner, you can't conclude an attempt to use any of the mentioned DIYs to fix a P0113 code. 

P0113 code diagnostics: How do I fix the P0113 code?

The good news is that when the P0113 code is triggered, you can apply two simple steps to resolve the issue without needing to visit the nearest repair shop, which might cost you a lot in labor cost.

Here's what you need to do at home to fix the P0113 code

  • Confirm the issue 

Before you move into any other step further, you must confirm that your vehicle has an issue with the P0113 code. You might notice some of the common symptoms of this code, but before scanning your computer and confirming that there is such a code, you can't go ahead and perform any repairs. 

To do so, you can use any common OBDII scanner which you can connect to the computer, and it will read any code from the computer. On the OBDII scanner, you will see the error code displayed, and you will also see a text indicating the definition of this code.

Keep in mind that there are some advanced OBDII scanners that might even provide you with additional details about what needs to be done and how much it will cost you to fix this problem. In some tools, you might even get an idea about whether this problem is serious or not.

However, you don't have to purchase the most advanced OBDII scanner because you won't need it, and we never advise it. Unless you are an experienced mechanic who will use this tool daily, you won't need it more than a couple of times once in a while, which means that you can easily borrow it from a friend or purchase a cheaper one. 

  • Inspected the IAT sensor 

The IAT sensor is one of the common culprits triggering the P0113 code. Go ahead and locate this sensor by referring to the intake manifold closer to the throttle body. If you couldn't find it, you can always refer to your vehicle's owner’s manual to get better guidance. 

Carefully take out the IAT sensor and perform a visual inspection to determine any other damages that might be caused due to issues with other engine components. 

Test the resistance range for your vehicle's IAT sensor. This range should be within what is specified in your vehicle's owner’s manual. Their resistance can be different from a vehicle to another, and that's why we can't give you with typical range for the IAT sensor here. 

Once confirming that the IAT sensor had issues with air resistance, the only solution for you is to replace it immediately to get the problem resolved and get rid of the P0113 code. 

However, if the IAT sensor looked just fine for you, go ahead and proceed to the next step to check the air filter. 

  • Inspect the air filter 

The next step here is to look at the air filter, a black box located on the engine block. If you again had a hard time locating it, refer to your vehicle's owner’s manual, giving you accurate guidance on where to find it. 

Carefully remove the black box from the top of the air filter and make sure not to affect any of the surrounding connections. Many inexperienced drivers might cause significant damage to some of the connections as they remove the black box. That's the last thing you want to deal with.

After removing the black box, take out the air filter and Inspect it. Keep in mind that the air filter must be placed in a certain direction. That's why we recommend that you take a quick picture of how the air filter was placed so we can understand how to put it back. After taking out the air filter, using a dry cloth, remove any remaining debris or dirt from the air filter compartment.  

Before installing the new filter, a good idea would be to compare it to the old filter to ensure that they are identical, confirming that you purchased the right filter. Place the new air filter in the right location and seal the black box properly before leaving. 

If none of the mentioned messages resolved your P0113 issue, your next step is to reach out to a professional mechanic who would have certain manufacturer tests to determine the primary cause of this issue that might not be related to the air filter IAT sensor. 

Will the P0113 code clear itself? 

No, most engine codes do not clear themselves after fixing the problem. That's why one important step in fixing or getting rid of any error code is to clear it. To do so, you can again use the OBDII scanner and connected it to the vehicle. 

Request the scanner to delete or clear any previous inactive errors. After clearing the P0113 code, it is also recommended that you perform a second scan to ensure that the error goes away, indicating that you successfully resolved the problem.

If there did not go away, it means that your attempts to get rid of the P0113 code were not successful, and you have to take your vehicle to the nearest repair shop to get the problem resolved permanently. 

Can I drive my car with a P0113 code?

While you still can drive your vehicle with a P0113 code, it is never recommended because it can introduce major damages to the engine.

Running on lean fuel is not a good thing, and if your problem is linked to a minor issue like an IAT sensor or air-fuel filter, you can solve it what's the lowest repair costs. However, if you are delayed there appears, you can simply introduce measure issues that might cost you thousands of dollars if not damaging the entire engine. 

How much does it cost to resolve the P0113 code?

P0113 code repair costs differ significantly depending on the primary cause of the issue. For instance, if the problem is linked to the intake air temperature sensor itself, it might cost you somewhere between $87.00 and $96.00 on parts only. Labor costs might be somewhere between $34 and $42. 

On the other hand, if your problem is as simple as replacing an air filter, expect to pay about $15.00 to $25, which is not considered an expensive repair compared to other maintenance in your vehicle. 

Keep in mind that labor cost is a good component when it comes to any mechanical repairs. Therefore, even parts are not very expensive; sometimes, the dealership's hourly rate at the dealership can be extremely higher than at the repair shop.

Therefore, evaluate your situation and see whether you can fix the problem yourself, visit a small repair shop, or probably end up having it resolved at the dealership with a higher price. 

Did you know that some owners of modern peoples preferred to visit the dealership? Yes, this is because when an experienced mechanic at the dealership fixed the problem, there is a very small potential to measure damages to surrounding components. These mechanics usually know the brand very well, and they know exactly what needs to be done.
