Dodge Journey Manifold Absolute Pressure (MAP) Sensor Guide (2009-2020)
Experiencing poor fuel economy or a rough idle in your Dodge Journey? Your MAP sensor might be the culprit.
- A failing MAP sensor on a Dodge Journey commonly causes poor fuel economy, rough idle, and a check engine light with codes P0106, P0107, or P0108.
- Replacement is extremely easy, requires no special tools, and can be done in minutes, making it an ideal DIY job.
- For best results, choose an OEM Mopar part or a high-quality aftermarket brand like Delphi or NGK (NTK) to avoid compatibility issues.
- Before replacing the sensor, quickly inspect for cracked or disconnected vacuum hoses, as they can cause identical symptoms.
Is Your Dodge Journey's MAP Sensor Failing?
A faulty Manifold Absolute Pressure (MAP) sensor can cause noticeable problems with your Dodge Journey's performance. Because this sensor directly influences the air-fuel mixture and ignition timing, a bad reading can throw the whole system off balance. The most common sign is the check engine light turning on, but you might also notice other issues during your drive.
Key Failure Symptoms
- Poor Fuel Economy: One of the most common complaints. A bad sensor can trick the engine's computer into sending more fuel than necessary, causing your Journey to run rich and burn through gas faster.
- Rough Idle: Your engine may shake, sputter, or sound unstable when you're stopped at a light.
- Loss of Power: The vehicle may feel sluggish and slow to accelerate. It might feel like it's struggling to get up to speed.
- Check Engine Light: A failing MAP sensor will almost always trigger a check engine light. Common trouble codes include P0106, P0107, and P0108.
- Hard Starting: The engine may take longer than usual to start because the computer can't determine the correct amount of fuel for startup.
Choosing the Right Aftermarket MAP Sensor
When it comes to engine sensors, quality matters. While OEM Mopar parts are the benchmark, several aftermarket brands offer reliable alternatives for your Dodge Journey. It's generally best to avoid the cheapest, no-name options, as they can fail prematurely or provide inaccurate readings, leading to persistent performance issues.
Brand Quality Tiers
- Top Tier (OEM Equivalents): Brands like Delphi and NGK (NTK) are often original equipment manufacturers for many car brands and are highly regarded for their quality and reliability. Choosing one of these is the safest bet for a long-lasting repair that performs like the original.
- Mid-Grade (Reliable Aftermarket): Standard Motor Products (SMP) and Walker Products are well-known aftermarket brands that generally offer good quality parts. They provide a solid balance of price and performance. For SMP, stick to their standard line rather than budget-tier offerings.
- OEM: Mopar is the original part for your Journey. It guarantees perfect fit and function but comes at a higher price point. If your budget allows, this is always a great choice.

DIY Installation is Easy
Replacing the MAP sensor on a 2009-2020 Dodge Journey (both 2.4L and 3.6L engines) is a very simple job that most owners can do in under 15 minutes with no special tools. The sensor is located right on top of the intake manifold under the plastic engine cover. The process is straightforward: pull the cover off, disconnect the electrical clip, twist the old sensor to unlock it, and pull it out. Installation is just the reverse.
Frequently Asked Questions
Where is the MAP sensor located on my Dodge Journey?
The MAP sensor is located directly on top of the engine's intake manifold. You can access it by simply pulling the plastic engine cover straight up and off. It's a small sensor with an electrical connector plugged into it.
Can I clean my MAP sensor instead of replacing it?
Sometimes, cleaning the sensor tip with a dedicated mass airflow sensor cleaner can resolve minor issues caused by carbon or oil buildup. However, if the sensor's internal electronics have failed, cleaning will not help, and replacement is necessary. Given the low cost of a new part, replacement is often the more reliable solution.
Are there any recalls for the Dodge Journey MAP sensor?
No, there are no specific recalls or widespread Technical Service Bulletins (TSBs) from Dodge or the NHTSA for MAP sensor failure on the 2009-2020 Dodge Journey.
What is the difference between a MAP and a MAF sensor?
A MAP (Manifold Absolute Pressure) sensor measures air pressure in the intake manifold, while a MAF (Mass Airflow) sensor measures the volume and density of air entering the engine. Both help the ECU calculate the correct air-fuel ratio. Your Dodge Journey relies primarily on the MAP sensor for this calculation.
