Your Guide to the Manifold Absolute Pressure (MAP) Sensor for the 2016-2024 Kia Sorento
Experiencing poor fuel economy or a rough idle? Your Sorento's MAP sensor might be the culprit.
- A bad MAP sensor on a Sorento commonly causes a check engine light, poor gas mileage, rough idle, and lack of power.
- Before replacing, try cleaning the sensor with MAF sensor cleaner, as it can get contaminated with oil.
- Replacement is very easy for a DIYer, requiring only basic tools and less than 30 minutes.
- Ensure you buy the correct part for your Sorento's specific engine, as different engines use different sensors.
Is Your Sorento's MAP Sensor Failing?
A bad Manifold Absolute Pressure (MAP) sensor can cause noticeable problems with how your Sorento drives. Because it provides key data for the air-fuel mixture, a faulty sensor can make your engine run too rich (too much fuel) or too lean (not enough fuel). This can lead to poor performance and, if ignored, potential damage to other components like the catalytic converter.
Symptoms of a Bad MAP Sensor
If your MAP sensor is going bad, you'll likely notice one or more of these signs:
- Check Engine Light: This is often the first sign. Common trouble codes related to the MAP sensor include P0106, P0107, and P0108.
- Poor Fuel Economy: A bad sensor can trick the ECU into using more gas than needed, causing you to fill up more often.
- Rough Idle: Your Sorento might shake or run unevenly when stopped at a light.
- Lack of Power: You may feel that your SUV is slow to accelerate or feels sluggish when you press the gas pedal.
- Black Smoke from Exhaust: This can happen if the engine is running too rich with fuel due to a bad sensor reading.
- Failed Emissions Test: An incorrect air-fuel ratio will lead to higher emissions.
Check This First!
Before you replace the sensor, it's a good idea to inspect it. On some Sorento engines, like the 2.5L, the sensor can get dirty with oil and moisture from the crankcase ventilation system. Sometimes, simply cleaning the sensor with a dedicated Mass Airflow (MAF) sensor cleaner can solve the problem.

Choosing an Aftermarket MAP Sensor
When replacing your Sorento's MAP sensor, you have options besides the expensive dealership part. Aftermarket brands offer a range of quality and price points.
Brand Quality Tiers
- Premium Aftermarket (OEM-level Quality): Brands like Delphi, NGK (NTK), and Standard Ignition (SMP) are well-known for producing high-quality sensors that meet or exceed the original part's specifications. They are a reliable choice for long-term performance.
- Quality Mid-Range: Brands such as Holstein and Walker Products offer a good balance of quality and value. Holstein, for example, states they use high-quality materials and offer a 3-year/36,000-mile warranty.
- Economy/Value: Brands like Skyward, Global Parts, and True Tech provide a more budget-friendly option. While they can get your vehicle back on the road, their long-term durability may not match that of the premium brands.
Common Ordering Mistake
The 2016-2024 Kia Sorento was offered with several different engines (2.4L, 3.3L, 2.0T, 2.5L, 2.5T). Each engine may use a different MAP sensor. Always verify the part number and fitment for your specific year and engine before ordering. Using your vehicle's VIN is the best way to ensure you get the correct part.
