Where is the gas gauge sensor in 2005 Chevy Malibu located?

In a 2005 Chevy Malibu, the gas gauge sensor is integrated into the fuel pump assembly, which is located inside the fuel tank. To access the sensor, you'll typically need to remove the rear seat and the access panel or drop the fuel tank itself. The sensor works by detecting the fuel level and sending this information to the gauge on the dashboard. If you're experiencing issues with the gas gauge, it may be related to the sensor or the wiring connected to it.
