What causes the check engine light to come on in a Dodge Avenger?

Causes of the Check Engine Light in a Dodge Avenger
The check engine light in a Dodge Avenger can come on due to various reasons. Here are some common causes:
1. Loose or damaged gas cap: A loose or damaged gas cap can cause the check engine light to come on. The gas cap acts as a seal for the fuel system and helps maintain pressure in the fuel tank. If the gas cap is loose or damaged, it can lead to reduced gas mileage and increased emissions.
2. Sensor problem: A sensor problem can also trigger the check engine light in a Dodge Avenger. The specific sensor that is malfunctioning can vary, and it would require a mechanic to diagnose the issue using a scanner.
3. Maintenance required: The check engine light can also come on to indicate that regular maintenance is required. The onboard diagnostic computer generates and stores trouble or fault codes that indicate the need for service. Once the necessary maintenance or repairs are performed, the check engine light can be reset.
It’s important to note that a blinking check engine light indicates a critical issue, while a solid light reflects a non-emergency situation. If the check engine light is blinking, it is recommended to have the issue diagnosed by a mechanic as soon as possible.
Please keep in mind that these are general causes, and it is always best to have a qualified mechanic diagnose the specific issue with the check engine light in a Dodge Avenger.
