Fuel Gauge

[Calvette]

On a trip, had about half tank and all of a sudden the gauge went to empty and the warning light came on....Any ideas... Thanks in advance

Welcome to the CAC!

Even though your Vette is a 2001 and this service bulletin appears to apply to 1997-2000 models, it still looks like this is your problem:

1997-2000: Service Bulletin: Inaccurate/Erratic Fuel Level Gauge Readings

The symptoms you describe match the description in this Knowledge Base Service Bulletin.

Hope this helps!

My '99 Convertible does the exact same thing. Usually the gauge is between 1/2 and 1/4 when it all of a sudden goes to empty and the low fuel warning comes on. If I turn the ignition off then back on, the gauge returns to normal.

What do the service bulletins mean? Will Chevrolet fix the problem at their cost?

Have your dealer try this. It should be covered under your warranty. If your car isn't under warranty it should not be expensive. It takes less than a half hour to do.


Erratic Fuel Gauge Reading (Reprogram the PCM) #02-06-04-010 - (02/21/2002)

Some owners may comment about the fuel gauge intermittently indicating an empty reading and then return to the correct fuel level indication.

This condition may result when fuel blends containing aggressive sulphur compounds react with the fuel sender assembly, which may result in voltage spikes being induced on the fuel level signal to the PCM. Use of another fuel blend may reverse this reaction and return the system to normal operation.

Reprogram the PCM with the new service calibration which is available in the January 2002, Techline TIS 2000 release. Use the TIS 01/2002 or later data update.
