What sensors are on a Dodge Journey?
The Dodge Journey uses a broad array of sensors across engine, drivetrain, safety, and comfort systems. In short, you’ll find engine-management sensors, transmission and speed sensors, airbags and tire-related sensors, plus climate and exterior monitoring devices. Below is a categorized guide to the most common sensors found on Journey models from 2009 through 2019.
Engine and emissions sensors
What these sensors monitor
They continuously track engine conditions to manage fuel, ignition, and exhaust aftertreatment. The typical Dodge Journey includes:
- Mass Air Flow (MAF) sensor
- Manifold Absolute Pressure (MAP) sensor
- Oxygen (O2) sensors — upstream and downstream
- Throttle Position Sensor (TPS)
- Crankshaft Position Sensor
- Camshaft Position Sensor
- Engine Coolant Temperature Sensor
- Intake Air Temperature (IAT) sensor
- Fuel Pressure Sensor
- EGR valve position/flow sensor (where equipped)
- Oil Pressure Sensor or oil pressure switch
- Oil Level sensor (on some models)
- Knock Sensor
These sensors supply data to the engine control unit (ECU) to optimize fuel delivery, ignition timing, and emissions controls.
Transmission and drivetrain sensors
What these sensors monitor
To control shifts and monitor the drivetrain, the Journey typically uses:
- Vehicle Speed Sensor (VSS)
- Transmission Fluid Temperature Sensor
- Transmission Input Shaft Speed Sensor
- Transmission Output Shaft Speed Sensor
- Shift position/PRNDL sensor
- Torque Converter Clutch status/feedback sensor (where applicable)
These sensors help manage gear shifts, transmission health, and overall drivetrain performance.
Safety and occupant protection sensors
What these sensors do
They support airbags, seat occupancy, and stability systems. Common items include:
- Airbag deployment/acceleration sensors (impact sensors)
- Front passenger Occupant Classification System (seat weight sensor)
- Tire Pressure Monitoring System (TPMS) sensors
- Wheel Speed Sensors (for ABS and stability control)
- Yaw Rate / Lateral Acceleration Sensor (stability control)
These sensors detect collisions, monitor tire pressure, and assist in vehicle stability and occupant safety.
Climate, comfort, and exterior sensors
What these sensors affect
They help regulate cabin comfort and respond to environmental conditions. Typical sensors include:
- Outside Air Temperature sensor
- Interior Cabin Temperature sensor (and related humidity sensing in some HVAC systems)
- Ambient Light Sensor (features such as automatic headlights may rely on it)
These sensors support climate control efficiency and vehicle lighting/visibility features, adapting to outside conditions.
Model-year considerations and variability
Model-year differences
The Dodge Journey spanned multiple engine options (2.4L I4 and 3.6L V6) and trim levels, so sensor complements can vary by year. The lists above cover the most commonly reported sensors across typical Journeys, with some additional sensors appearing on specific trims or later model years.
Summary
In essence, a Dodge Journey relies on a comprehensive sensor network to manage engine performance, transmission operation, safety systems, and cabin comfort. From MAF and crankshaft position sensors to TPMS and airbags accelerometers, these sensors continuously feed data that keeps the vehicle running smoothly, safely, and efficiently. For a precise, year-specific sensor set, consult the exact service information for your model year and engine configuration.
