Chrysler Concorde Engine Intake Manifold Temperature Sensor Guide (1993-2004)
Fixing poor performance and bad fuel economy in your Concorde starts with this simple sensor.
- A bad IAT sensor commonly causes a Check Engine Light with code P0113, poor fuel economy, and rough idling.
- This is an easy and inexpensive DIY repair that can be done in under 15 minutes.
- Aftermarket brands like Standard Ignition offer reliable, cost-effective replacements for this part.
- Before buying a new sensor, try cleaning the old one and checking its electrical connector for damage or corrosion.
Is a Failing IAT Sensor a Big Deal?
Yes, it can be. When the Intake Air Temperature (IAT) sensor fails, it sends wrong information to your Concorde's engine computer. The computer might think the air is -40°F when it's actually a warm day. This causes the computer to inject too much fuel, a condition called "running rich." This leads to poor gas mileage, rough idling, and can even make it hard to start your car, especially in cold weather. Ignoring it can lead to more serious issues like engine misfires and carbon buildup.
A very common code associated with a failing IAT sensor is P0113 (Intake Air Temperature Sensor 1 Circuit High Input). This means the sensor is sending a voltage signal that is too high to the engine computer, which often happens when the sensor fails or has a bad connection.
Choosing the Right Aftermarket Sensor
For a vehicle like the 1993-2004 Chrysler Concorde, aftermarket IAT sensors offer a great balance of quality and value. The technology for this type of sensor is well-established, and aftermarket brands produce reliable replacements. There is no significant performance difference compared to the original OEM part for this specific sensor, making an aftermarket choice a smart financial decision.
Brand Options:
- Standard Ignition (Standard Motor Products): A well-regarded brand in the aftermarket world. They are known for producing parts that are direct-fit replacements and undergo extensive testing. Customer reviews for their IAT sensors are generally positive, often mentioning good fit and fixing engine issues. They are a solid choice for reliability.
- True Tech: While reviews for this specific sensor are not widely available, True Tech is generally known as a brand associated with NAPA Auto Care centers and receives positive feedback for honest service and quality parts in the general auto repair context. They represent a budget-friendly option that should perform reliably for this application.
Typical Costs for a New IAT Sensor

Frequently Asked Questions
Where is the IAT sensor located on my Chrysler Concorde?
The IAT sensor is typically located in the air intake path, between the air filter box and the engine's throttle body. It's a small, two-wire sensor that screws or pushes into the intake ducting or the intake manifold itself. A quick search online for your specific model year and engine will often show a diagram of its exact location.
Can I replace this sensor myself?
Yes, this is a very beginner-friendly job. It usually involves unplugging the electrical connector, and then unscrewing or pulling the old sensor out. The new one goes in its place. The whole process can take less than 15 minutes with basic tools.
Are there any recalls for this part on my Concorde?
Searches of the NHTSA database did not show any specific recalls for the Intake Air Temperature sensor on the 1993-2004 Chrysler Concorde. There was a recall (98V-184) for fuel rail o-rings on 1993-1997 models, but this is unrelated to the IAT sensor.
What's the difference between an IAT and a MAF sensor?
The IAT sensor measures air temperature. A Mass Air Flow (MAF) sensor measures the total volume and mass of air entering the engine. On many modern cars, the IAT sensor is built into the MAF sensor housing. However, on many Concorde models, it is a separate, standalone sensor.
