This PI is being superseded to update instructions on how to get the new service kit. Please discard PIT4280.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
The fuel gauge is erratic and displays the incorrect fuel level in below-freezing weather.
Example concerns:
- The fuel tank is ¾ full. While driving, the fuel gauge gradually starts to display a lower fuel level, beyond the reduction that is due to engine fuel consumption. The fuel gauge may subsequently recover to an accurate fuel level display.
- After being parked in below-freezing weather, the vehicle is started and the fuel gauge displays a reading of "E". With driving, the gauge reading may slowly recover towards the actual fuel level. If the ignition is then cycled, the fuel gauge may now display the actual fuel level.
Note: A P0463 Diagnostic Trouble Code may or may not be set. If it is set, the fuel gauge is commanded to "E".
The condition is related to excess water in non-ethanol fuel at below-freezing temperatures causing ice crystals in the fuel which interfere with the proper operation of the fuel level sender. Engineering has released new a fuel level sensor with a cover. The new fuel level sensor with a cover will prevent the ice crystals from interfering with the operation of the fuel level sensor.
Recommendation/Instructions:
The new fuel level sensor with cover can be obtained by filling out the form below and faxing it or E-mail it to the Warranty Parts Center (WPC). It will also be necessary to order O-Ring Seal P/N 22682111 from Service Parts separately to replace the old seal with the new one upon reassembly of the fuel pump module with sender into the fuel tank.
Important NOTE WHEN PRINTING THIS FORM: If the form prints out on two pages, make certain you fax BOTH pages so that the WPC receives all the needed information. Missing information will delay or prevent the part from being shipped.
