Service bulletin PIC4996C
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
This PI offers diagnostic tips to a technician when diagnosing a possible fuel level sensor concern. The tech is advised to ohm test the sensor at the terminals located on top of the fuel module while performing a sweep test. If the test fails the technician is instructed to replace the sensor and then perform the sweep test again. If the test passes the technician is instructed to reinstall the fuel module in the tank and if the test fails with the new sensor the technician is advised to replace the fuel module.
