Is Your Chrysler 300's MAP Sensor Failing?
A faulty Manifold Absolute Pressure (MAP) sensor can cause a surprising number of issues that you might mistake for a more serious engine problem.

Choosing the Right Aftermarket MAP Sensor
When replacing the MAP sensor on your 2012-2023 Chrysler 300, you have several options outside of the dealership. Here’s an honest look at the brands available and where they generally stand in terms of quality.
- OEM-Equivalent Brands (Top Tier): Brands like Delphi and NGK (NTK) are often original equipment manufacturers or produce parts to the same strict standards. Delphi sensors are noted for being internally protected against moisture and vibration. NTK sensors are manufactured to meet or exceed OE specifications for fit and function. Choosing one of these is the closest you can get to OEM quality without the Mopar box.
- Reliable Aftermarket (Mid-Tier): Standard Ignition (SMP) and Walker Products have a long history in the aftermarket. They produce reliable sensors that offer a good balance of price and quality. These are a solid choice for a daily driver where you want a dependable part without the premium price tag.
- Budget-Friendly (Entry-Tier): Brands like Crown Automotive, Global Parts, and Holstein often provide the most affordable options. While they can be a good fit for a tight budget, quality can sometimes be inconsistent compared to higher-tier brands. They are functional replacements, but may not have the same longevity or precise calibration as more expensive options.
How Much Does a New MAP Sensor Cost?
The cost can vary depending on the brand you choose and whether you do the work yourself. Replacement is a simple DIY job for most owners.
| Part/Service | Estimated Cost |
|---|---|
| New OEM (Mopar) Part | $70 - $120 |
| New Aftermarket Part | $26 - $90 |
| Shop Labor | $50 - $100 |
Frequently Asked Questions
Where is the MAP sensor located on my Chrysler 300?

What happens if I ignore a bad MAP sensor?
Driving with a bad MAP sensor for an extended period can lead to several problems. You'll experience poor fuel economy, reduced engine power, and potentially damage your catalytic converter over time due to an incorrect air-fuel mixture. You will also fail any emissions tests.
Do I need to reset the computer after replacing the MAP sensor?
Yes, after replacing the sensor, it's a good practice to clear the engine trouble codes with an OBD2 scanner. Alternatively, you can disconnect the negative battery terminal for about 15-20 minutes to reset the ECU. 🎬 See how to fix a P0108 check engine code This allows the computer to recalibrate with the new sensor's readings.
