A failing IAT sensor will almost always turn on the Check Engine Light. The most common trouble codes are P0112 (Sensor Circuit Low Input) and P0113 (Sensor Circuit High Input). A P0113 code often means the computer sees a very high voltage, which it interprets as an impossibly cold temperature like -40°F.

For the 2007-2017 Jeep Patriot, you don't necessarily need to buy an expensive OEM sensor from the dealer. Aftermarket brands offer a reliable and affordable alternative. The key is to choose a brand with a good reputation for producing quality electronic sensors.
- Standard Ignition: Standard Ignition (also known as Standard Motor Products or SMP) is a well-regarded aftermarket manufacturer. They have been making replacement parts for over 100 years and are known for extensive testing to ensure their parts perform like the original. For a critical but simple sensor like the IAT, a brand like Standard is a dependable choice that offers good value.
Pro Tip: Since this is a simple, external engine sensor, a quality aftermarket part like one from Standard Ignition is a smart choice. It provides the same function as the OEM part at a lower cost without sacrificing reliability for this specific application.

Frequently Asked Questions (FAQ)
Where is the IAT sensor located on a 2007-2017 Jeep Patriot?
The IAT sensor is located in the flexible black air intake duct. You can find it between the air filter housing and the engine's throttle body. It is a small, black plastic sensor that pushes into a rubber grommet in the duct.
🎬 See how to replace the sensor on your Jeep Patriot.Can I clean the IAT sensor instead of replacing it?
Sometimes, cleaning the sensor tip with a dedicated mass air flow or electronics cleaner can solve issues if they are caused by dirt or oil buildup. However, if the sensor has failed internally, which is common, cleaning will not help and replacement is the only fix. Given the low cost of a new sensor, replacement is often the more reliable solution.
What happens if I ignore a bad IAT sensor?
Ignoring a bad IAT sensor can lead to long-term problems. You will experience poor fuel economy, reduced engine power, and potentially a rough idle. In some cases, it can make the engine difficult to start, especially in cold weather. Over time, running with the wrong air/fuel mixture can lead to increased engine wear or damage to the catalytic converter.
Are there any recalls for the Jeep Patriot IAT sensor?
As of early 2026, there are no specific recalls issued by the NHTSA for the Intake Air Temperature sensor on 2007-2017 Jeep Patriot models. A recall (NHTSA 16V-907) was issued for the crankshaft/camshaft sensor wiring harness on some 2016 models, but this does not involve the IAT sensor.
