Why would a check engine light come on for a Dodge Avenger?

Reasons for a Check Engine Light in a Dodge Avenger
The check engine light in a Dodge Avenger can come on for various reasons. Here are some common causes:
1. Loose Gas Cap: A loose or improperly tightened gas cap can trigger the check engine light.
2. Sensor Problem: Issues with sensors in the vehicle, such as the oxygen sensor or the mass airflow sensor, can cause the check engine light to come on.
3. Catalytic Converter Problem: A malfunctioning catalytic converter can lead to the check engine light coming on.
4. Engine Misfire: A severe misfiring of the engine can trigger the check engine light to blink, indicating a critical issue.
5. Other Engine Problems: Various engine-related problems, such as a faulty ignition coil or a problem with the fuel system, can also cause the check engine light to come on.
It’s important to note that a blinking check engine light usually indicates a more serious problem that requires immediate attention, while a steady light suggests a non-emergency situation that still requires a mechanic’s diagnosis.
If the check engine light comes on in your Dodge Avenger, it is recommended to schedule an appointment with a mechanic to diagnose and address the issue as soon as possible.
