Jeep Compass 2007-2012 Manifold Absolute Pressure Sensor: A Complete Guide
Experiencing rough idle or poor performance in your Jeep Compass? Your MAP sensor might be the culprit.
- A bad MAP sensor on a 2007-2012 Compass causes check engine lights (P0106, P0107, P0108), rough idle, poor acceleration, and bad gas mileage.
- Replacement is simple for DIYers; the sensor is on the back of the intake manifold and held by one bolt or a twist-lock.
- While budget brands are available, choosing a quality aftermarket brand like Delphi or Standard Ignition is recommended for reliability.
- Before replacing the sensor, check for vacuum leaks or damaged wiring, which can cause similar symptoms.
Is Your Jeep Compass MAP Sensor Failing?
A faulty Manifold Absolute Pressure (MAP) sensor can cause a range of noticeable engine problems in your 2007-2012 Jeep Compass. Because this sensor's data is critical for engine performance, you'll likely experience issues that affect drivability. Ignoring these symptoms can lead to worse fuel economy, failed emissions tests, and potentially damage other expensive components like the catalytic converter.
Common Symptoms of a Bad MAP Sensor
- Check Engine Light: This is often the first sign. The computer will store fault codes like P0106, P0107, or P0108. 🎬 Watch how to diagnose these specific engine light codes.
- Poor Engine Performance: You might notice sluggish acceleration, hesitation, or a general lack of power.
- Rough Idle: The engine may shake or run unevenly when stopped.
- Engine Stalling: The engine might stall unexpectedly, especially at low speeds or when coming to a stop.
- Bad Fuel Economy: If the sensor sends bad data, the engine may use more fuel than necessary.
- Black Smoke from Exhaust: This indicates a rich fuel mixture, where too much gasoline is being burned.
Choosing the Right Aftermarket MAP Sensor
When replacing the MAP sensor on your Compass, you have a choice between OEM (Mopar) and various aftermarket brands. For critical sensors like the MAP, quality matters. While OEM Mopar parts are considered the benchmark, some aftermarket brands offer a good balance of quality and value.
Tier 1: Premium Aftermarket & OEM-Equivalent
These brands are known for manufacturing parts for automakers directly or for having a strong reputation for quality and reliability. They are your best bet outside of a Mopar box.
- Delphi: A major OEM supplier known for high-quality electronics. Delphi sensors are often considered a top-tier alternative to factory parts.
- Standard Ignition (SMP): A well-regarded brand in the aftermarket, often seen as a reliable choice, though some users report occasional inconsistency with sensors.
- Mopar: The original equipment manufacturer. While typically the most expensive, it guarantees a perfect fit and performance.
Tier 2: Reputable Aftermarket
These brands provide a good balance of affordability and performance. They are a solid choice for budget-conscious repairs.
- Spectra: Known for a wide range of fuel and engine management parts.
- Walker Products: A long-standing company specializing in fuel and emission control components.
- Holstein: Offers a range of sensors and other electronic parts for European and domestic vehicles.
Tier 3: Economy Brands
These brands focus on being the most affordable option. While they can get the job done, their longevity and performance consistency may not match higher-tier brands.
- Crown Automotive / Omix-Ada: Very popular in the Jeep community for a wide variety of parts. While some have success with their sensors, others prefer Mopar for critical electronics.
- Global Parts: Generally positioned as a budget-friendly option.
Pro Tip: For critical electronic sensors, spending a little more on a reputable brand like Delphi or Standard Ignition can save you from future headaches and ensure your Compass runs smoothly. Some owners insist on Mopar for any engine sensor to avoid compatibility issues.
How Much Does a MAP Sensor Replacement Cost?
Replacing the MAP sensor is a relatively inexpensive repair. The part itself is affordable, and the labor is minimal since the sensor is fairly easy to access on the 2.0L and 2.4L engines.

Frequently Asked Questions
Where is the MAP sensor located on a 2007-2012 Jeep Compass?
On the 2.4L engine, the MAP sensor is located on the intake manifold, on the back side of the engine. 🎬 See exactly where the sensor is located on your engine. It can be tricky to see from the top, but it is reachable. Some videos show it's easier to access from underneath the vehicle after jacking it up safely. It is a small black plastic sensor with an electrical connector and is held in by a single bolt or a twist-lock mechanism.
Can I replace the MAP sensor myself?
Yes, this is a very DIY-friendly job for most home mechanics. The process involves disconnecting the battery, unplugging the electrical connector, removing one bolt or twisting the sensor, and pulling it out. The most difficult part 🎬 Follow this step-by-step guide to replace the sensor yourself. is reaching the sensor's location on the back of the intake manifold.
Are there any recalls for the MAP sensor on the Jeep Compass?
There are no specific recalls for the Manifold Absolute Pressure sensor on the 2007-2012 Jeep Compass. A recall for some 2016 models mentioned crankshaft or camshaft sensors causing stalling, but not the MAP sensor. Always check for recalls using your vehicle's VIN on the NHTSA website.
What do MAP sensor error codes like P0106, P0107, and P0108 mean?
These are common codes related to the MAP sensor.
- P0106: Indicates the sensor's performance is out of the expected range, meaning its readings don't match what the computer expects based on other sensors.
- P0107: Means the sensor's circuit voltage is too low, suggesting a short to ground or a faulty sensor.
- P0108: Means the sensor's circuit voltage is too high, suggesting a short to voltage or a faulty sensor.
