Oh no! It looks like your Jeep has spewed out a check engine light in your dashboard. The problem could be severe but don’t worry; we are here to help.
As time goes by, vehicles get more advanced. These new technologies make cars safer, more comfortable, and easier to drive. But there is also a downside to this, as cars get more complex, with more gadgetry and circuitry, they’re more likely to break down.
The Jeep P0113 code indicates a problem with your vehicle’s intake air temperature sensor. By the end of this article, you’ll find all that you need to learn about the Code and fix it.
What Does the Jeep P0113 Code Mean?
The P0113 Code signifies an issue with the vehicle’s intake air temperature sensor or IAT. In some Jeeps, they build the IAT into the Mass Air Flow (MAF) detector. In other vehicles, they mount it to the air filter duct housing.
When the IAT sensor finds a change in temperature in the vehicle intake, it sends a signal to the Engine Control Module (ECM). This data is then used for various purposes throughout the vehicle.
The IAT measures the temperature with the means of a thermistor. A drop in resistance equates to a rise in temperature. If the air intake temperature is inadequate, it will trigger the P0113 Code.
When there is a very high electrical voltage to the ECM, it also triggers the Code. This high voltage is not to be confused with an actual sensor reading of a high temperature in the air intake.
For instance, an IAT with a high circuit of 5 volts communicates to the engine control module that the air intake temperature is negative 40 degrees Fahrenheit.
Common Symptoms of a Jeep P0113 Code
Your Jeep will show the following symptoms of the P0113 Code:
- Your vehicle is unable to start.
- There may be problems with the pre-ignition; this can be due to lean burn.
- Increased fuel consumption.
- Engine misfiring.
- The vehicle’s check engine light is on.
- The ECM goes into fail-safe mode.
How do you diagnose the Jeep P0113 Code?
Other than looking for the symptoms, the best way to diagnose the problem is with an OBD II scanner. It’ll pinpoint the problem with your vehicle. You could also check the wiring between the IAT and the PCM.
Another thing you can do is to check the air temperature when the engine is warm. A test of the resistance of the IAT could also determine if it’s defective.
What Causes the Jeep P0113 Code?
The main problem which could be causing the P0113 Code is a faulty Intake Air Temperature (IAT) or Mass Air Flow (MAF) sensor. Most vehicles have the IAT sensor built right into the MAF sensor, so if the MAF fails, the IAT fails with it.
If these sensors are not changed, the vehicle’s performance will start decreasing with time, and fuel economy will also worsen.
Dirty air intake
A problem as simple as dirt could also cause the P0113 Code in the air intake. People regularly drive their vehicles without giving any importance to their cleanliness. This dirt and grime can accumulate on your vehicle’s sensitive components, like the air intake system, causing problems.
Failure of the PowerTrain Module
The Power Train Module (PCM) is the brain of your vehicle. It manages the engine and transmission of your vehicle with the data it receives from the various sensors located around it.
If the PCM gets damaged or fails, it also takes the functionality of various sensors like the IAT, causing error codes to appear. It can be the most expensive cause to repair or replace.
Shorted or open harness of the Intake Air Temperature Sensor
Like most sensors on a vehicle, the wiring can cause problems for the sensor if it is damaged in some way. If the wiring harness of the IAT sensor gets shorted, it can also trigger the P0113 Code.
Whether it’s rats or water, or just a bumpy ride, the wiring of any vehicle can be susceptible to many problems leading to error codes.
How to Fix The Jeep P0113 Code
Replacing the Faulty Sensors
The most widespread solution to the P0113 Code is the replacement of the intake air temperature sensor or the complete replacement of the mass air flow sensor.
Make sure that’s the issue, though. Otherwise, it could just be a costly replacement without any fix.
Cleaning the Air Intake
You can also clear the P0113 Code if you clean the intake. Get your water hose and sponge and clean the air intake and sensors.
Repairing or Replacing the Power Control Module
Although the PCM failure is the least common cause of the P0113 Code, sometimes it can happen and be the most expensive fix.
The PCM controls most mechanical functions of the vehicle, so its replacement will cost a pretty penny.
Checking the Wiring
If you find compromised wiring, be it a short circuit or an open wire, you should fix it immediately. This could be a quick fix and help you avoid high costs by going to a mechanic.
Resetting faulty computer
Verify the code type with an OBD-II scanner, and reset the fault code. Test drive the car to see if the code clears.

Having an engine code in your vehicle can be scary, but the issue is not serious most of the time. Although these codes can be annoying, they help people diagnose issues with their vehicles.
With the help of these codes, you don’t have to worry about figuring out the problems yourself. You can rely on the codes to tell you exactly what the problem is. With this new knowledge, we hope you can easily resolve the code.
How serious is the P0113 Code?
Although many people consider the Jeep P0113 Code to be a moderately severe issue, it can be a pain if you don’t get it fixed in time.
The problem is that when you leave it, it can cause other issues, too, such as internal engine damage.
How do I avoid the P0113 Code?
Regular maintenance of your vehicle can help you avoid codes like this. If you service your vehicle regularly, it can go a long way in keeping it problem free.
Can I drive with the P0113 Code?
Yes, you can drive your vehicle with the P0113 error code for a short period of time, but we don’t recommend it. The reason for this is that if you drive your Jeep for a long time with this code, the lean burn could cause internal problems in your engine.
