A Guide to the Manifold Absolute Pressure Sensor for the 2012-2016 Chrysler Town & Country
If your Town & Country is running rough or losing power, the MAP sensor is a likely and easy-to-fix culprit.
- A failing MAP sensor causes common issues like rough idle, poor fuel economy, and a check engine light with codes P0106, P0107, or P0108.
- Replacement is extremely easy for a DIYer, requiring no special tools and taking less than 15 minutes.
- High-quality aftermarket brands like Delphi and NGK offer a reliable, cost-effective alternative to the more expensive OEM Mopar part.
- Ignoring a bad MAP sensor can lead to wasted fuel and potential damage to other components like the catalytic converter over time.
Understanding the MAP Sensor in Your Town & Country
The Manifold Absolute Pressure (MAP) sensor is a small but critical component for your van's 3.6L engine. It acts as one of the main sources of information for the engine computer, telling it how hard the engine is working based on intake manifold pressure. When this sensor fails, the computer receives bad data, leading to a host of noticeable engine performance problems. Fortunately, on the 2012-2016 Town & Country, this sensor is located right on top of the engine and is one of the easiest parts for a DIYer to replace.
Is an Aftermarket MAP Sensor a Good Choice?
For many electronic parts, sticking with the original equipment (OEM) Mopar part is a safe bet. However, for a simple and easily accessible sensor like the MAP sensor, a high-quality aftermarket part offers excellent value without sacrificing reliability. Top-tier aftermarket brands like Delphi and NGK are often original equipment suppliers to many automakers and produce parts that meet or exceed OEM specifications. Budget-friendly brands are also available, but for a critical sensor, choosing a reputable aftermarket name provides greater peace of mind.
Pro Tip: Check Before You Replace
Sometimes, the sensor itself isn't faulty, but its connection is. Before buying a new part, unplug the sensor, remove it (it twists and pulls out), and check for oil or carbon buildup on the tip. Cleaning it with a dedicated mass airflow sensor cleaner may solve the problem. Also, ensure the rubber O-ring is in good condition to prevent vacuum leaks.
Choosing the Right Aftermarket Brand
Not all aftermarket parts are created equal. Here is a breakdown of the available brands based on their reputation for quality and performance in engine management sensors.
| Brand Tier | Brands | General Assessment |
|---|---|---|
| Tier 1: Premium Aftermarket | Delphi, NGK | Often OE suppliers, these brands are known for high-quality materials and rigorous testing that meets or exceeds OEM standards. Excellent reliability and a safe choice for replacing critical sensors. |
| Tier 2: Standard Aftermarket | Standard Ignition (SMP), Walker Products | Well-known, reputable brands with a long history in the aftermarket. They offer a good balance of quality, performance, and price, making them a solid choice for most repairs. |
| Tier 3: Economy | Crown Automotive, Global Parts (GPD), Holstein | These brands provide a cost-effective solution. While they are designed to be direct-fit replacements, they may not have the same long-term durability or stringent quality control as premium brands. Best for budget-conscious repairs where easy replacement access minimizes future labor risk. |
Frequently Asked Questions
Where is the MAP sensor located on my 2012-2016 Town & Country?
The MAP sensor is located on the top of the engine's upper intake manifold, just under the plastic engine cover. It is easily accessible in the front, center of the engine assembly.
Can I clean my MAP sensor instead of replacing it?
Yes, sometimes cleaning can resolve the issue, especially if the sensor is just dirty. Use a cleaner specifically designed for electronic sensors like a Mass Airflow (MAF) sensor cleaner. Do not use harsh chemicals like brake cleaner. If cleaning doesn't fix the symptoms, a replacement is needed.
Are there any recalls for the MAP sensor on this van?
No, searches for official NHTSA recalls or widespread Technical Service Bulletins (TSBs) for the MAP sensor on the 2012-2016 Chrysler Town & Country did not yield any results. Failures are typically due to age and normal wear.
Do I need to disconnect the battery to change the MAP sensor?
While it is a good safety practice to disconnect the battery's negative terminal for any electrical work, it is not strictly necessary for a simple plug-and-play sensor like this. The replacement takes only a few minutes. After replacement, the check engine light may turn off on its own after a few drive cycles, or you can clear it with an OBD2 scanner.
