DESCRIPTION
The Fuel Lever Sensor is an important input to the Control Module for the enhanced evaporative system diagnostic. The fuel level information is needed for the Control Module to know the volume of the fuel tank. The fuel level affects the rate of charge in the air pressure in the EVAP system. Several of the Enhanced Evaporative System diagnostic sub-tests are dependent upon the correct fuel level information. Refer to Evaporative (EVAP) Emissions System Diagnostic Tests. Testing and Inspection
