I need to find the right front cowl ground stud/panel to check for proper grounding of the fuel level sensor.

Hi,

I'm looking at the wiring schematic. It shows the ground for the fuel level gauge to be located behind the left kick panel. See pic 1 below.

The schematic indicates the ground to be G200.

Let me know if this helps.

Take care,

Joe

Thank you, it was very helpful. Can you tell me if the fuel level sensor would be grounded at the same spot?

Hi,

The ground for the rheostat itself is with the fuel pump. The body control module receives a fuel level sensor signal by supplying power to the rheostat which functions as a resister.

Does the fuel gauge do anything? I'm not sure what you are experiencing.

If you haven't already, we need to run the cluster through a self-test mode.

Follow the directions in pic 2. Once you determine if there is a code, follow the diagnostics in the remaining pics.

Let me know what you find or if you have other questions.

Take care,

Joe

The problem that I have is that the Body Control Module was not sending the fuel sensor information to the monitors and so my van wouldn't pass a smog test. There was a fault in the BCM, and I had it repaired but wanted to be sure that there was a proper ground for the fuel level sensor as that was where the problem was. I was trying to locate the ground for the sensor to check to make sure it was making a solid connection. The help you provided was exactly the information I needed and the fact that you took the time to highlight what I was asking about I consider going above and beyond. Thank you so much.
