Dodge Durango Manifold Absolute Pressure (MAP) Sensor: 2018-2025
Is your Durango running rough or losing power? It could be this simple sensor.
- A bad MAP sensor causes poor performance like rough idle, hesitation, and bad gas mileage.
- For 2022-2023 5.7L models, check for a cracked intake manifold before replacing the sensor, as symptoms are identical.
- Replacement is extremely easy for DIYers and takes less than 15 minutes on the 5.7L Hemi.
- Premium aftermarket brands like Delphi and NGK offer OEM-quality performance for less cost.
Is Your Durango's MAP Sensor Failing?
A bad Manifold Absolute Pressure (MAP) sensor can cause a lot of frustrating engine problems. Because it provides key data for the air-fuel mixture and ignition timing, a failure can make your Durango run poorly. The symptoms often start small but can get worse over time. Ignoring them can lead to poor fuel economy, failed emissions tests, and potentially damage other engine components.
Key Failure Symptoms
- Check Engine Light: This is the most common sign. The computer will log fault codes, often between P0105 and P0109.
- Rough Idle: The engine may vibrate or sound uneven when you're stopped.
- Poor Acceleration: You might feel a significant lack of power or a delay when you press the gas pedal.
- Bad Fuel Economy: If the sensor tells the computer to send too much fuel, your gas mileage will drop.
- Hesitation or Stalling: The engine may stumble during acceleration or even stall when you come to a stop.
- Black Smoke from Exhaust: This is a sign of the engine running too rich (too much fuel), which can be caused by a bad MAP sensor reading. 🎬 Watch: A visual guide to common bad MAP sensor symptoms
IMPORTANT: Check for a Cracked Intake Manifold
For 2022-2023 Dodge Durango 5.7L V8 models, there is a Technical Service Bulletin (TSB 09-012-24) for a cracked intake manifold. The symptoms—rough idle, engine misfires (like code P0301), and an illuminated check engine light—are nearly identical to those of a bad MAP sensor. Before replacing the sensor, it is critical to inspect the intake manifold for cracks, especially at the front left side, to avoid a misdiagnosis.

When replacing your MAP sensor, you have a choice between the original Mopar part and several aftermarket brands. For a simple electronic sensor like this, a high-quality aftermarket part can offer the same performance as OEM for a lower price.
Brand Quality Tiers
- Premium Aftermarket (Delphi, NGK/NTK): These brands are often original equipment suppliers to many automakers. They are known for rigorous testing and high-quality standards, making them a reliable choice that often meets or exceeds OEM specifications.
- Standard Aftermarket (Standard Motor Products, Walker Products): These are well-established brands in the aftermarket with a reputation for producing reliable parts. Standard Motor Products (SMP) in particular is a huge manufacturer that also produces parts for other brands. They offer a good balance of quality and value.
- Economy/Value (Crown Automotive, Spectra): These brands can be a budget-friendly option. However, search results show some user complaints about fitment issues or lower-quality materials with brands like Spectra and Crown. While they may perform adequately, they might not have the same long-term durability as premium options.
Pro Tip: Installation
On the 5.7L Hemi engine, replacing the MAP sensor is a very simple job. After removing the plastic engine cover, the sensor is located on the front of the intake manifold. You simply disconnect the electrical plug, twist the sensor counter-clockwise to unlock it, and pull it straight out. The new sensor pushes in and twists to lock. No special tools are needed, making it an easy 15-minute DIY fix.

Frequently Asked Questions
Can I just clean my MAP sensor?
Unlike some other sensors, MAP sensors are generally not cleaned. The sensing element is internal and sealed. Failures are typically electronic and cannot be fixed by cleaning. Replacement is the only reliable solution.
What's the difference between a MAP and a MAF sensor?
Your Durango uses a MAP (Manifold Absolute Pressure) sensor. It measures pressure in the intake. Other vehicles use a MAF (Mass Air Flow) sensor, which measures the volume and density of air entering the engine. Both serve a similar purpose—helping the ECU calculate the correct air-fuel ratio—but they are not interchangeable.
Is a Mopar sensor better than aftermarket?
For this specific part, a premium aftermarket sensor from a brand like Delphi or NGK is an excellent alternative to the more expensive Mopar part. These companies are OE suppliers themselves and produce high-quality electronics. Budget brands may be less reliable, but top-tier aftermarket options provide OEM-level performance for less money.
How difficult is it to replace the MAP sensor on my Durango?
For the 2018-2025 models, especially with the 5.7L V8, it is extremely easy. It requires no tools other than your hands to remove the engine cover. The sensor itself twists out. The entire job can be done in under 15 minutes, making it one of the easiest DIY repairs you can perform.
