Reasons for Check Engine Light in Dodge Avenger
The check engine light in a Dodge Avenger can come on for various reasons, and it’s essential to address the underlying issue to prevent potential damage to the vehicle. Here are some common reasons for the check engine light to illuminate:
1. Loose Gas Cap or Sensor Problem: The check engine light in a 2012 Dodge Avenger can be caused by a loose gas cap or a sensor problem.

There is a recall for these issues, but it’s essential to verify if the specific vehicle is included in the recall.
5. Electrical or Transmission Issues: The check engine light can also be related to electrical or transmission problems, such as a faulty alternator or issues with the transmission control module.
6. Regular Maintenance: The check engine light can also come on when regular maintenance is required, and it will stay on until it is reset after the required maintenance is performed.
It’s crucial to have the issue diagnosed by a qualified mechanic to ensure the proper resolution.
