Dodge Charger fuel gauge fluctuates between full and empty with check engine light on, indicating fuel level sensor issue on Dodge Charger

Some Dodge Charger owners report experiencing fluctuating fuel gauge readings and an illuminated check engine light, which often indicate a fuel level sensor issue. This problem can result in inaccurate fuel level readings, with the gauge potentially stuck on empty or full, or failing to move at all. Additionally, some owners may notice symptoms such as poor fuel efficiency, difficulty starting the vehicle, and the engine running either rich or lean. To resolve these issues, it is advisable to diagnose the fuel pump assembly for performance problems and check the sensor output voltage and fuel pump functionality. Prompt attention to this matter is crucial for maintaining accurate fuel level readings and ensuring proper vehicle performance.
