Check of serviceability and replacement of the block of the fuel level sensor

See the prevention at the beginning of the Section Procedure of Dumping of Pressure of Fuel.

Check

 PERFORMANCE ORDER

  1. The car also establish to Poddomkratta it on props.
  2. Connect ohmmeter probes to plugs of the electric socket of the fuel level sensor (see an illustration below) and measure resistance.
  1. Under the car disunite the electric socket of assembly of the fuel pump / fuel level sensor and measure sensor block resistance, having connected an ohmmeter to plugs of the necessary wires of the socket (the 5.2 l engine is shown).
  1. At first measure sensor block resistance at the full fuel tank. Resistance has to make about 120 Ohms.
  2. Wait for almost full emptying of a tank and repeat the procedure of measurement of resistance - now it has to make 10 Ohms.
  3. If indications differ from stipulated above, or full of a float of the sensor very minor change of resistance sets in motion, replace assembly of the pump with the sensor.

In a different way checks of the fuel level sensor its removal from the car (see item 1 - 4) and measurement of resistance is at extreme provisions of a float.


  1. Measure resistance of the block of the fuel level sensor at the extreme provisions of its float corresponding full (the top situation) and empty (the lower situation) to a tank.

Replacement

 PERFORMANCE ORDER

  1. Remove the fuel tank (The section Removal and installation of the fuel tank).
  2. Uncover access to the fuel level sensor block / the fuel pump (see an illustration) the fuel tank.
  3. Take from a tank assembly of the sensor with the pump. Try not to damage float-operated assembly of the sensor.
  4. You make installation upside-down. Do not forget to replace laying of a flange.
