Chrysler Intrepid (1995-2003) Intake Manifold Temperature Sensor Guide
Having engine problems with your Intrepid? A bad intake air temperature sensor could be the culprit.
- A bad IAT sensor on your Intrepid will most likely cause a Check Engine Light with codes P0111, P0112, or P0113.
- Symptoms directly impact driveability, including rough idle, poor fuel economy, and hesitation.
- For the 2.7L engine, replacement is extremely easy, requiring only a single socket to change the sensor on top of the intake manifold.
- Quality aftermarket brands like Standard Ignition or True Tech are reliable and cost-effective choices for this part.
Is Your Intrepid Showing These Symptoms?
A failing intake air temperature (IAT) sensor can cause a surprising number of issues. Because the engine's computer relies on this sensor for correct air-fuel mixture, a bad reading can throw everything off. You might notice one or more of the following problems.

| Symptom | Description | Severity |
|---|---|---|
| Check Engine Light | This is the most common sign. A faulty IAT sensor will often trigger diagnostic trouble codes like P0111, P0112, or P0113. | 🎬 Learn how to test and replace a sensor with these codes.Moderate |
| Poor Fuel Economy | If the sensor incorrectly tells the computer the air is cold, the engine will run rich (too much fuel), wasting gas. | Minor |
| Rough Idle or Stalling | An incorrect air-fuel mixture can make the engine idle unevenly or even stall, especially when it's warming up. | Moderate |
| Hard Starting | The engine may be difficult to start, particularly in cold weather, if the computer gets the wrong temperature reading and provides the wrong fuel mixture for cranking. | Moderate |
| Engine Hesitation or Sluggish Acceleration | A bad sensor can confuse the computer during acceleration, leading to a sluggish or hesitant response when you press the gas pedal. | Moderate |
A Note on Cleaning
Sometimes, the sensor probe is just dirty with oil or carbon buildup, which can insulate it and cause bad readings. Before replacing the sensor, you can try cleaning it with a dedicated mass airflow sensor cleaner. However, on a high-mileage vehicle, replacement is often the more reliable fix.
Choosing the Right Aftermarket Sensor
For the 1995-2003 Chrysler Intrepid, you don't necessarily need to buy an expensive OEM Mopar part. Quality aftermarket brands offer a reliable and cost-effective alternative. The key is to choose a reputable brand.
- Standard Ignition (SMP): A well-known aftermarket brand that has been around for a long time. While some of their product lines have been outsourced, they are generally considered a quality option for sensors and ignition components. Their parts are often engineered to meet or exceed original specifications.
- True Tech: This is a product line from Standard Ignition. It is designed to offer a good quality part at a competitive price point, often functioning identically to the main Standard-branded part.
For a critical but simple sensor like the IAT, both Standard Ignition and its True Tech line are solid choices that provide good value without sacrificing reliability.
Cost of Replacing an Intrepid IAT Sensor
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket Part | $28 - $57 |
| Shop Labor | $50 - $100 |
| Total Professional Replacement | $78 - $157 |

Where is the IAT sensor located on my Chrysler Intrepid?
On the 2.7L V6 engine, the IAT sensor is threaded directly into the top of the plastic upper intake manifold, located near the ignition coils. On other Intrepid engines, it is typically found in the air intake tube between the air filter box and the throttle body.
Can I drive my Intrepid with a bad IAT sensor?
Yes, you can usually still drive the vehicle. However, you will experience poor performance, reduced fuel economy, and potentially hard starting. It is not a critical failure that will leave you stranded, but it should be addressed to prevent long-term issues like carbon buildup and to restore proper engine function.
Are there any recalls for the IAT sensor on the 1995-2003 Intrepid?
No, a search of NHTSA records shows no specific recalls for the intake air temperature sensor on the 1995-2003 Chrysler Intrepid. Most issues are related to age and normal wear.
What tools do I need to replace the IAT sensor?
For the 2.7L engine, the job is very simple. You will typically only need a ratchet and a 3/4-inch socket to unscrew the old sensor and install the new one. Always be careful not to overtighten the new sensor, as it threads into a plastic manifold.
