## 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.
