if your talking about the fuel level sensor (that tells how much fuel is in the tank), it is located in the fuel tank. accessible from under the back seat or by removing the entire fuel tank from under the car.
It is located on the fuel pump module which is located in the fuel tank. The fuel tank will need to be removed from the vehicle in order to service the fuel level sensor/sending unit.
the sensor is on the gas tank-if you remove the rear bench seat, there is an access plate to get to the top of the tank. Located under that is the fuel pump/fuel sensor level sensor. Remove the o-ring and lift the assembly out. On a scale of 1 to 10 (10 being the most difficult) it is a 3 or 4, tops.
The Fuel Level Sending Unit, or Fuel Level Sensor, is located in your gas tank with the Fuel Pump Module. The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The sending unit consists of a float, an arm, and a variable resistor track (card).
The Fuel Pressure Regulator is located within fuel pump module. The fuel pressure regulator controls fuel system pressure. The PCM cannot detect a clogged fuel pump inlet filter, clogged in-line fuel filter, or a pinched fuel supply or return line. However, these could result in a rich or lean condition causing the PCM to store an oxygen sensor or fuel system diagnostic trouble code.
Both of these sensors are connected with the Fuel Pump Module. Here is a diagram:
Both the fuel level sensor/sending unit and the fuel tank pressure sensor are located on or in the fuel pump module.
The fuel tank will need to be lowered in order to gain access to the fuel tank pressure sensor which will be the black sensor on top of the fuel pump module.
The fuel tank will need to be removed in order to remove the fuel pump module to gain access to the fuel level sending unit attached to the side of the fuel pump module.
This is if it is an internal filter, if it is not you still have to pull the whole bottom of the back seat out and look for the inspection plate.
Relieve the fuel system pressure by first
removing the fuel pump fuse. Then, start the engine and allow it to run
until it stalls. Crank the engine for 2 to 3 seconds to release the pressure Turn the ignition off.
Step 2
Disconnect
the negative battery cable. Remove the rear seat bottom and the
inspection hole cover. Disconnect the electrical and quick connectors
and remove the six screws. Remove the fuel level sensor unit and the
fuel pump assembly. Then, take out the flange and snap fit portion of
the fuel pump.
Step 3
Remove
the fuel tank temperature sensor harness, the fuel level sensor flange,
and the fuel pump connector. Disconnect the quick connectors from the
fuel level sensor, and remove the fuel level sensor from the chamber.
Take out the fuel filter.
Step 4
Put
the new fuel filter in the chamber, followed by the fuel level sensor.
Attach the quick connectors to the fuel sensor. Connect the fuel pump
connector and put the fuel level sensor flange and fuel tank
temperature sensor harness back.
Step 5
Place
the fuel pump assembly inside the tank. Replace the screws and
electrical connectors. Reattach the quick connectors. Reconnect the
negative battery cable.
Step 6
Start your car
and check for leaks, and make repairs if necessary. When repairs are
complete, replace the inspection hole cover and the rear seat bottom.
The fuel level sensor located on the fuel pump is giving a false reading. You need to have the fuel level sensor replaced. or the fuel pump replaced. The sensor might not come seperately
