Low Fuel Light Error?

[dsteinGA]

Recently, my low fuel light will come on and the guage will show below empty (as though there was no power to the guage) if I'm stopped at a light or idling for a bit.  Very odd.  Does it regardless of how much gas is in the tank.  I'm not sure if it's electrical or if it's just the sending unit.

 

Any ideas?

 

Thanks,

Description and Operation

 

The IPC displays the fuel level as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the fuel level percent. The fuel gauge defaults to empty if:

 

 

The PCM detects a malfunction in the fuel level sensor circuit.

The IPC detects a loss of class 2 communications with the PCM.

When the fuel level is less than a pre-determined value, the low fuel indicator illuminates.
