The engine light on your 2015 Dodge Journey can indicate various issues, ranging from minor to serious. Understanding the potential causes and solutions is crucial for maintaining your vehicle's performance and safety.

Common Causes of Engine Light Activation

Several factors can trigger the engine light in your Dodge Journey:

  • Loose or Damaged Gas Cap: A common issue that can lead to fuel evaporation and trigger the engine light.
  • Faulty Oxygen Sensor: This sensor monitors the exhaust and can affect fuel efficiency if malfunctioning.
  • Catalytic Converter Problems: Issues with this component can lead to increased emissions and decreased performance.
  • Mass Airflow Sensor Failure: This sensor measures the amount of air entering the engine, and its failure can disrupt engine performance.
  • Engine Misfire: Problems with spark plugs or ignition coils can cause misfires, leading to engine light activation.

Steps to Diagnose the Issue

If your engine light is on, follow these steps for diagnosis:

1. Check the Gas Cap: Ensure it is tight and undamaged.

2. Use an OBD-II Scanner: This tool reads error codes from the vehicle's computer, helping identify the specific issue.

3. Inspect for Visible Issues: Look for any obvious signs of damage or leaks under the hood.

4. Consult a Mechanic: If you cannot identify the problem, a professional can provide a thorough diagnosis.
