Dodge Durango (2011-2023) Engine Intake Manifold Temperature Sensor Guide
Dealing with a check engine light and rough performance in your Durango? It could be a bad intake temperature sensor.
- A bad IAT sensor commonly triggers check engine light codes P0113 and P0112.
- Before replacing the sensor, always check the wiring and connector for damage or a loose fit, as this is a frequent cause of the problem.
- Replacement is extremely easy, requiring no special tools and taking only a few minutes, making it an ideal DIY job.
- Quality aftermarket brands like Standard Ignition offer a reliable and affordable alternative to the more expensive OEM Mopar part.
Is Your Durango's IAT Sensor Failing?
A failing Intake Air Temperature (IAT) sensor on a 2011-2023 Dodge Durango can cause noticeable problems. Because the engine's computer relies on this sensor for key calculations, a bad reading can throw things off. You might notice your check engine light is on, your engine idles roughly, or your fuel mileage gets worse. In some cases, you could experience hesitation when you accelerate. Often, the issue isn't the sensor itself but the wiring or connector. Before replacing the part, it's always a good idea to check for loose connections or damaged wires.

When it's time to replace the IAT sensor, you have a choice between the original equipment manufacturer (OEM) part from Mopar and various aftermarket options. For a simple sensor like this, an aftermarket part is often a reliable and cost-effective choice.
- OEM (Mopar): The Mopar sensor (Part No. 5149182AB) is a direct replacement for the original. It guarantees perfect fit and function, but it's usually the most expensive option.
- Premium Aftermarket (e.g., Standard Ignition): Brands like Standard Ignition are well-regarded in the aftermarket. Their sensors are designed as direct-fit OE replacements, made with high-quality materials to withstand engine conditions, and undergo extensive testing for reliability. For many Durango owners, a brand like this offers the best balance of quality and price.
- Value-Priced Aftermarket: There are cheaper options available. While they can work, their long-term reliability and the quality of materials might not match up to premium aftermarket or OEM parts. Given the low cost of even premium aftermarket sensors, it's often worth spending a few extra dollars for peace of mind.
Pro Tip: Check the Connector First!
Many Durango owners have found that IAT sensor error codes were caused by a loose electrical connector or damaged wiring, not a failed sensor. Before you buy a new part, inspect the connector that plugs into the sensor. Make sure it's clean, dry, and clicks securely into place. Also, check the wires leading to the connector for any signs of cracking or breaks. Sometimes, simply cleaning the sensor tip with a dedicated mass air flow sensor cleaner can also resolve the issue.
