It is possible for a 2017 Dodge Journey check engine light to come on as a false alarm. There are a number of reasons why a check engine light might come on, and it is not always an indication of a serious problem. Here are some possible reasons why a check engine light might come on as a false alarm:

  • Loose or damaged gas cap: A loose or damaged gas cap can cause the check engine light to come on. Make sure the gas cap is tightened securely.
  • Dirty or clogged air filter: A dirty or clogged air filter can cause the check engine light to come on. Replacing the air filter should resolve your issue.
  • Failed oxygen sensor: A failed oxygen sensor can cause the check engine light to come on.

2017 Dodge Journey Check Engine Light, Why Is It So Important?

The 2017 Dodge Journey check engine light is an important part of your vehicle’s onboard diagnostics system. It is designed to alert you when there is a problem with one or more of your vehicle’s systems that could affect its performance or emissions. When the check engine light comes on, it means that your vehicle’s onboard computer has detected a fault in one of these systems and has stored a diagnostic trouble code (DTC) in its memory. The DTC is a code that represents the specific problem that has been detected, and it can be retrieved and used to diagnose the issue.

It is important to address the problem that caused the check engine light to come on as soon as possible because it can affect the performance and efficiency of your vehicle.
