How can I get access panel, to my fuel tank pressure sensor
Older models of Impalas did have access panels for the fuel pump, which would allow you to also access the fuel tank pressure sensor. However, by 2012, Chevy no longer included the fuel pump access panel. To change the sensor, you are going to have to drop the tank. Once the tank has been removed, you can cut and design your own access panel if you so choose. If you do not have experience with this kind of fabrication, seek help from a professional. Good luck.
