Condition

Some customers may comment about inaccurate or erratic fuel gauge readings. A typical comment might be that it appears from the gauge reading that there is fuel available, yet the tank is nearly empty.

Cause

This condition may be the result of the corrosive effect of certain fuel blends on the contact surfaces of the fuel tank sender.





Vehicles built between the VIN breakpoints shown.





Vehicles built prior to VIN breakpoint shown.

Correction

Important:

^ When servicing the fuel tank module or the fuel sender, DO NOT replace both parts. Only replace the appropriate part to repair the customer's concern.

^ The complete fuel level sender assembly P/N 22683260 is no longer available through GMSPO. This assembly is now serviced by a fuel tank module P/N 88957239 (minus sender) and the fuel tank sender, P/N 22709333. These two parts are no longer sold as one unit and can only be purchased separately.

^ Dealers within the provinces of British Columbia, Quebec, New Brunswick and the State of Maine, should refer to Customer Satisfaction Campaign 00101, dated January, 2001.

When fuel gauge diagnosis in the Service Manual indicates the cause to be the fuel tank sender, replace the existing sender with a new sender, P/N 22709333, with improved corrosion resistant wiper contacts.

Important:
With the availability of this new fuel level sender kit, DO NOT replace the complete fuel level sender assembly, P/N 22683260.

To insure correct installation, follow the instructions contained in the kit and the service procedure in the applicable Service Manual
