Chrysler Town & Country (2002-2016) Engine Intake Manifold Temperature Sensor Facts
Fixing poor performance or a check engine light in your Town & Country might be as simple as replacing this small sensor.
- A failing IAT sensor commonly triggers a Check Engine Light with codes P0112 or P0113.
- Symptoms include reduced gas mileage, rough idling, and hesitation during acceleration.
- Replacement is a simple DIY task for most owners, typically taking less than 30 minutes.
- Standard Ignition is a reputable aftermarket brand for this part, offering a reliable alternative to OEM Mopar.
Is a Failing Intake Air Temperature Sensor a Major Problem?
When the Intake Air Temperature (IAT) sensor in your Town & Country starts to fail, it sends incorrect information to the engine's computer. The computer might think the air is much colder or warmer than it actually is, causing it to add too much or too little fuel. This can lead to noticeable issues like poor gas mileage, rough idling, and hesitation when you accelerate. 🎬 Watch: Common symptoms of a failing IAT sensor explained. While you can usually still drive the vehicle, ignoring the problem can lead to failed emissions tests and potentially cause other engine components to wear out faster.
A Note on Sensor Types for Town & Country
Depending on your minivan's year and engine (e.g., 3.3L, 3.8L, or the 3.6L Pentastar), the IAT sensor may be a standalone part or integrated with the Manifold Absolute Pressure (MAP) sensor. On many models, especially later ones, it's a combined unit. Always verify the correct part for your specific engine before purchasing.
Choosing the Right Aftermarket Sensor
For the 2002-2016 Chrysler Town & Country, the original equipment (OEM) sensor is made by Mopar. Aftermarket options provide a cost-effective alternative. Standard Ignition is a well-established brand in the aftermarket world, often considered a reliable choice for engine management parts like sensors. Forum discussions and mechanic reviews generally see Standard Motor Products (the parent company of Standard Ignition) as a quality supplier, sometimes even manufacturing parts for OEM brands. When choosing an aftermarket part, selecting a reputable brand like Standard Ignition ensures a better chance of proper fit and long-term reliability compared to no-name online options.
Cost of Replacing the Intake Temperature Sensor
The cost can vary based on your vehicle's specific engine and whether you do the work yourself or hire a professional.
| Part Type | Estimated Cost |
|---|---|
| New OEM (Mopar) | $35 - $70 |
| New Aftermarket (Standard Ignition) | $37.60 - $56.41 |
| Shop Labor | $50 - $125 |
DIY Installation
Replacing the IAT sensor is a straightforward job for most DIY mechanics. It is typically located on the intake manifold or the air intake duct, making it easily accessible. The process usually involves disconnecting the electrical connector, unscrewing or unclipping the old sensor, and installing the new one. This can often be done in under 30 minutes with basic hand tools.

Where is the IAT sensor located on a Chrysler Town & Country?
The location varies by engine. On older 3.3L/3.8L engines, it's often a screw-in sensor on the intake manifold. On the later 3.6L Pentastar engines, it is typically a push-in style sensor located in the air intake duct between the air filter box and the throttle body. Always consult a repair manual for your specific year and engine to be certain.
What are the common error codes for a bad IAT sensor?
The most common trouble codes are P0112 (Intake Air Temperature Sensor 1 Circuit Low) and P0113 (Intake Air Temperature Sensor 1 Circuit High). P0112 suggests the sensor is sending a signal indicating an extremely low temperature, while P0113 indicates an extremely high temperature or an open circuit. These codes will cause the check engine light to come on.
🎬 Watch: Diagnosing a P0113 code on a Town & Country.Are there any recalls for this sensor?
As of early 2026, there are no specific NHTSA safety recalls for the intake air temperature sensor on the 2002-2016 Chrysler Town & Country. Likewise, there are no widespread Technical Service Bulletins (TSBs) related to this specific part failing, indicating it is not a common factory defect.
Is the IAT sensor the same as the coolant temperature sensor?
No. The IAT sensor measures air temperature entering the engine. The Engine Coolant Temperature (ECT) sensor measures the temperature of the engine's coolant. Both are critical for engine management, but they are separate parts with different functions and locations.
