Does the Dodge Journey have a MAF sensor?
The Dodge Journey does use a Mass Air Flow (MAF) sensor in its intake system for both of its main engine options—the 2.4-liter four-cylinder and the 3.6-liter V6.
The Journey, produced from 2009 to 2019, relies on the MAF sensor to measure incoming air so the engine control module can precisely meter fuel. While some Chrysler/Jeep models rely on other sensors in certain configurations, the Journey’s engines incorporate a dedicated MAF sensor in the air intake path. Below is a concise guide to the engines offered and how the MAF sensor is located and tested.
Engine options in the Dodge Journey
Two primary powertrains were offered during the Journey’s production run, both of which use a MAF sensor to monitor air flow.
Note on variant engines
- 2.4L World Gasoline I4: Uses a MAF sensor in the intake tract to measure air flow for the engine control unit.
- 3.6L Pentastar V6: Uses a MAF sensor in the intake tract as part of the air-fuel metering system.
In typical Journey configurations with these engines, a MAF sensor sits in the air intake duct between the air box and the throttle body. For model-year specifics, consult a service manual for precise sensor part numbers and wiring diagrams.
MAF sensor location and testing basics
Where to look and how MAF sensors are typically diagnosed in the Journey's engines.
Testing and service tips
- Location: the MAF sensor is usually installed in the intake duct between the air filter housing and the throttle body for both the 2.4L and 3.6L engines.
- Appearance: a small, rectangular sensor with an electrical connector and a wiring harness routed to the engine control module.
- Diagnosis: symptoms of a failing MAF include rough idling, reduced fuel economy, check engine light, and poor acceleration. Testing may involve data logging with a scan tool, comparing live air flow readings, and cleaning or replacing the sensor as needed.
Always refer to the official service manual for your exact year and engine to confirm the sensor location, specifications, and replacement procedure.
Summary
Yes—the Dodge Journey employs a MAF sensor on its two main engines (2.4L I4 and 3.6L V6) to measure air intake for proper fuel metering. If you’re troubleshooting performance or fuel economy issues, inspecting the MAF sensor and the surrounding air intake components is a logical first step, with service details varying by year and configuration.
