Dodge Charger (2009-2023) Intake Air Temperature Sensor Guide
Is your Charger running rough or getting bad gas mileage? Its Intake Air Temperature sensor could be the problem.
- A bad IAT sensor on a Charger most often causes a Check Engine Light with codes like P0113, P0112, or P0111.
- Key symptoms include reduced gas mileage, rough idling, and hesitation when accelerating.
- Replacement is a very easy DIY job for most owners, usually taking less than 15 minutes with basic tools.
- For this part, a quality aftermarket brand like Standard Ignition is a reliable and budget-friendly alternative to a more expensive OEM Mopar part.
Is Your Charger's IAT Sensor Failing?
A faulty Intake Air Temperature (IAT) sensor can cause more than just a Check Engine Light. Because the sensor tells the computer how much fuel to add, a bad reading can make your Charger's engine run poorly. You might notice symptoms like a rough idle, hesitation when you step on the gas, or a noticeable drop in fuel economy. 🎬 Watch: 7 symptoms of a bad IAT sensor and costs In some cases, it can even make the engine hard to start, especially in cold weather.
Aftermarket vs. OEM for a Dodge Charger
When replacing the IAT sensor, you have two main choices: Original Equipment Manufacturer (OEM) from Mopar or an aftermarket part. For a simple electronic sensor like the IAT, a quality aftermarket brand provides a reliable and cost-effective solution. Brands like Standard Ignition are well-known in the industry and produce direct-fit replacement parts that meet or exceed original specifications. An OEM Mopar sensor is also an excellent choice but typically comes at a higher price point. Given the low failure rate and non-critical nature of this specific part, a reputable aftermarket sensor is a smart choice for most Charger owners.
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket | $22.32 - $56.41 |
| New OEM (Mopar) | $30 - $60 |
| Shop Labor | $50 - $100 |

Frequently Asked Questions
Where is the IAT sensor located on my Dodge Charger?
The location depends on your engine. On most Charger engines, including the 3.6L V6 and 5.7L HEMI V8, the IAT sensor is located in the plastic air intake tube between the air filter box and the throttle body. It is a small, two-wire sensor that typically twists and locks into place.

These are common diagnostic trouble codes related to the IAT sensor. P0113 (Circuit High Input) is one of the most frequent and means the computer is receiving a voltage signal from the sensor that is higher than expected, often indicating an open circuit or a failed sensor. 🎬 See how to diagnose and fix a P0113 trouble code P0112 indicates a circuit low input, and P0111 indicates a range/performance issue.
Can I just clean the IAT sensor?
Sometimes, the sensor probe can get contaminated with oil or dirt, which can affect its reading. You can try cleaning it with a dedicated mass air flow or electronics cleaner. However, if the sensor has failed internally, cleaning will not fix the problem and replacement will be necessary.
How do I know I'm ordering the right sensor?
The Dodge Charger has used a few different IAT sensors across its long production run and multiple engine options. It is critical to use your vehicle's year and engine (e.g., 3.6L V6, 5.7L HEMI, 6.4L HEMI) to find the exact fit. Part numbers can vary, so always confirm fitment for your specific model before ordering.
