FUEL LEVEL SENDING UNIT /
SENSOR
DESCRIPTION
The fuel gauge level sending unit is attached to the
side of fuel pump module. The level sensor is a vari-
able resistor.
OPERATION
Its resistance changes with the amount of fuel in
the tank. The float arm attached to the sensor moves
as the fuel level changes.
The fuel level input is used as an input for OBD II.
If the fuel level is below 15% of total tank capacity
several monitors are disabled. There are diagnostics
for the level circuit open and shorted.
REMOVAL
Remove fuel pump module. Refer to Fuel Pump
Module in this section.
(1) Depress retaining tab and remove the fuel
pump/level sensor connector from theBOTTOMof
the fuel pump module electrical connector (Fig. 2).
NOTE: The pump module harness on TOP of flange
is not serviceable or removable.

TEST ACTION APPLICABILITY
1NOTE: A loose gas cap could have caused this DTC to set. Make sure gas cap
is tight and in good condition. Ensure the gas cap meets OEM specifications.
Turn the ignition on.
With the DRBIIIt, read DTC's.
Is the DTC Specific Good Trip Counter displayed and equal to zero?All

No®Go To 4
2 To continue testing you will need Miller Tools #6872A (Evap System Pressure Pump)
and #8382 (Gas Cap Tester/Adapter).
WARNING: The test equipment is designed to be used to pressurize the
vehicles Evaporative System only. Using the equipment in a manner for
which it was not designed could be harmful.
WARNING: Keep lighted cigarettes, sparks, flames, and other ignition
sources away from the test area to prevent the ignition of explosive gases.
Keep the test area well ventilated.
NOTE: The fuel tank should have between 20% and 80% of fuel tank capacity
to properly test the Evap system.
Attach the power red source clip of Miller Tool #6872A to Battery (+) and the black
ground clip to Battery (-).
Perform the Evaporative System Pressure Pump self test that is specified on the
tester cover.
Remove gas cap and install Miller Tool #8382 on vehicle. Install gas cap to Miller Tool
#8382. Attach the pressure supply hose from Miller Tool #6872A to the fitting on
#8382.
Disconnect the vacuum supply hose at the Leak Detection Pump. Connect and apply
a continuous vacuum supply (i.e. 209Hg) to the Leak Detection Pump. A vacuum
pump such as an A/C recovery unit works well.
Turn the ignition on.
With the DRBIIItin System Tests, select Leak Detect Pump Test. Read instructions
and then press Enter. Select: #3 - HOLD PSI.
On Miller Tool #6872A, set the Pressure/Hold switch to Open and set the Vent switch
to Closed. Turn the pump timer On and watch the gauge.
NOTE: If the pressure does not build up, there is obviously a large leak in
the system and the presence of strong fuel odor may be present. A visual
inspection should find a leak of substantial size.
When the gauge pressure reaches 149H2O, turn the Pressure/Hold Valve to Closed.
Turn the pump timer off. Note the time and pressure. After 10 sec of stabilization
time.
Did the pressure drop more than 69H2O in 2 minutes?All
