Jeep Cherokee Manifold Absolute Pressure (MAP) Sensor Guide (2013-2023)
Is your Jeep Cherokee running rough or losing power? Your MAP sensor might be the culprit.
- A bad MAP sensor on a Cherokee causes poor fuel economy, rough idle, hesitation, and a check engine light (P0106, P0107, P0108).
- Replacement is very easy and can be done at home in under 30 minutes with basic tools.
- For this specific part, it is highly recommended to choose a Mopar (OEM) or a premium aftermarket brand like Delphi or NGK to avoid faulty parts.
- There are no recalls or TSBs specifically for the MAP sensor on this vehicle.
Is Your MAP Sensor Failing? Common Symptoms
A faulty MAP sensor can make your Cherokee run poorly. Because it sends bad information to the engine's computer, you might notice several problems. Look out for these common signs of failure:
- Check Engine Light: This is often the first warning. The light will come on, and a code scanner will likely show codes like P0106, P0107, or P0108. 🎬 Watch: P0106 code explained and how to fix it.
- Poor Engine Performance: You might feel like the Jeep is slow to accelerate or hesitates when you press the gas pedal.
- Rough Idle: The engine may shake or vibrate more than usual when you're stopped.
- Bad Fuel Economy: If the computer thinks there is more pressure than there really is, it will inject too much fuel, causing you to visit the gas station more often.
- Black Smoke from Exhaust: This is a sign of too much fuel being burned, which can be caused by a bad MAP sensor reading.
- Stalling: In some cases, the engine may stall unexpectedly, either while driving or at idle.
Could It Be Something Else?
Symptoms like a rough idle or hesitation can also be caused by a vacuum leak in one of the engine's hoses. Before replacing the sensor, it's a good idea to quickly check the vacuum hoses connected to the intake manifold for any cracks or loose connections.
Choosing the Right Aftermarket MAP Sensor
When it comes to electronic sensors for your Cherokee, quality matters. A cheap, poorly made sensor can fail quickly or even be bad right out of the box, causing the same problems you were trying to fix. Here’s a breakdown of the available aftermarket brands to help you choose.
Premium Aftermarket Brands
These brands are known for making high-quality electronic parts and are often suppliers for original equipment manufacturers (OEMs). They are your most reliable options next to buying a Mopar part from the dealer.
- Delphi: A well-respected brand that makes many original parts for car companies. It's considered a top-tier choice for sensors.
- NGK (NTK): NGK is famous for spark plugs, and their sensor division, NTK, has a strong reputation for quality and reliability. While rare, defects can happen with any brand.
- Standard Ignition (SMP): A solid mid-to-upper-tier brand. Generally considered a reliable choice, though some mechanics have experienced occasional issues with their sensors.
Standard & Budget Brands
These brands offer a lower price, but the quality can be inconsistent. They might be a good fit for a tight budget, but there is a higher risk of getting a faulty part.
- Crown Automotive: This brand specializes in Jeep parts. However, owner feedback is very mixed. Some have used their parts for years with no issues, while others report parts failing immediately. It can be a gamble.
- Walker Products, Holstein, Global Parts: These brands fall into the budget-friendly category. While they can save you money upfront, be aware that the risk of premature failure is higher compared to premium brands.
OEM vs. Aftermarket: The Bottom Line
For a critical sensor like the MAP, most experienced mechanics recommend using either the original Mopar part or a premium aftermarket brand like Delphi or NGK/NTK. Paying a little extra often saves you the headache of diagnosing the same problem twice if a budget part fails.
Replacement Cost for a 2013-2023 Jeep Cherokee

Frequently Asked Questions
Where is the MAP sensor located on my Jeep Cherokee?
The location depends on your engine. On the 2.4L 4-cylinder engine, the MAP sensor is on the back of the intake manifold and is often easiest to reach from underneath the vehicle. 🎬 See this video for the 2.4L sensor location and replacement. On the 3.2L V6 engine, it is much easier to find. It's on the top front of the intake manifold, right in the open after you remove the plastic engine cover.
Can I replace the MAP sensor myself?
Yes, this is a very DIY-friendly job for both engines. For the 3.2L V6, it takes only a few minutes. 🎬 Watch a quick walkthrough of the MAP sensor replacement. For the 2.4L, it may take a little longer since you might need to get under the car. The sensor is typically held in by one small bolt or a simple twist-lock mechanism. No special tools are required beyond basic hand tools.
Are there any recalls for the Jeep Cherokee MAP sensor?
No. As of now, there are no specific recalls or Technical Service Bulletins (TSBs) from Jeep or the NHTSA for MAP sensor failure on the 2013-2023 Jeep Cherokee.
What is the most common mistake when ordering this part?
The most common mistake is buying a low-quality, cheap sensor that fails quickly or doesn't work correctly. This leads to frustration and having to do the job a second time. It's worth spending a few extra dollars on a reputable brand to ensure it works right the first time.
