Is Your Jeep Cherokee Running Rough? It Could Be the IAT Sensor
If your 2013-2023 Jeep Cherokee is experiencing poor fuel economy, a rough idle, or has the check engine light on, a faulty Intake Air Temperature (IAT) sensor could be the culprit. This small sensor plays a big role in how your engine performs. When it fails, it can send incorrect information to your engine's computer, leading to a host of noticeable problems. Fortunately, this is one of the easier and more affordable DIY repairs you can perform.
Symptoms of a Bad IAT Sensor in a Jeep Cherokee
A failing IAT sensor usually doesn't cause the vehicle to break down completely, but it will make it run poorly. Here are the most common signs:
- Check Engine Light: This is often the first sign. The most common trouble code associated with a bad IAT sensor is P0113, which indicates a high voltage reading from the sensor. This code often means the computer thinks the incoming air is -40°F, causing it to inject far too much fuel. 🎬 Watch this video to understand the P0113 code and sensor circuit.
- Poor Fuel Economy: When the sensor fails, the engine's computer often defaults to a rich fuel mixture, meaning it uses more gas than needed. This can cause a noticeable drop in your miles per gallon.
- Rough Idle and Hard Starts: An incorrect air-fuel ratio makes it difficult for the engine to idle smoothly or start up easily, especially in cold weather.
- Engine Hesitation or Lack of Power: Your Cherokee might feel sluggish or hesitate during acceleration because the engine isn't getting the right fuel mixture for the power demand.
- Black Smoke from Exhaust: In some cases, the overly rich fuel mixture can result in black smoke coming from the tailpipe, which is unburnt fuel.
No Specific Recalls Found
As of early 2026, there are no specific NHTSA recalls or Technical Service Bulletins (TSBs) for the Intake Air Temperature sensor on the 2013-2023 Jeep Cherokee. Always check for the most current information using your vehicle's VIN.
Choosing a New Aftermarket IAT Sensor
When replacing the IAT sensor, you have the choice between an OEM part from Mopar and an aftermarket part. For a simple sensor like this, a quality aftermarket brand offers a reliable and cost-effective solution.
Standard Ignition Brand Quality:
Standard Motor Products (SMP) is a well-known aftermarket manufacturer that has been around for a long time. They produce parts under different lines, and quality can vary. Their main "Standard" brand is generally considered a solid choice, while their budget "T-Series" has a reputation for lower quality. For a component like the IAT sensor, a Standard Ignition part is a dependable option that can perform as well as the original without the higher cost of an OEM part.
Easy DIY Replacement
For the 2.4L and 3.2L engines in the Cherokee, the IAT sensor is located on the main air intake tube between the air filter box and the engine's throttle body. It is held in by a simple twist-lock mechanism. The replacement involves unplugging the electrical connector, turning the old sensor about 90 degrees counter-clockwise, and pulling it out. The new one pushes in and twists to lock. 🎬 Watch a quick walkthrough of the 2.4L sensor replacement process. The entire job can be done in under 15 minutes with no special tools.

Frequently Asked Questions
Where is the IAT sensor located on my Jeep Cherokee?
The IAT sensor is located on the plastic air intake duct that runs from the air filter box to the engine. It's a small, black plastic sensor with an electrical connector, typically found just before the throttle body.
🎬 See how to remove the air intake to access the sensor.What is the most common trouble code for a bad IAT sensor?
The most common code is P0113, which stands for "Intake Air Temperature Sensor 1 Circuit High Input." This means the sensor is sending a signal that the computer interprets as extremely cold air.
Can I clean the IAT sensor instead of replacing it?
Sometimes, cleaning the sensor tip with a dedicated electronic or MAF sensor cleaner can resolve issues if it's just dirty. However, if the sensor's internal thermistor has failed, which is common, cleaning will not help and replacement is necessary. Given the low cost of a new part, replacement is often the best course of action.
Is an aftermarket IAT sensor good enough?
Yes, for this specific part, a quality aftermarket sensor from a reputable brand like Standard Ignition is a reliable and budget-friendly choice. The technology is not complex, and these brands often produce parts that meet or exceed original specifications.
