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. To Poddomkratta the car also establish it on props.
  2. Connect щупы an ohmmeter 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 resistance of the block of the sensor, having connected an ohmmeter to plugs of the necessary wires of the socket (the engine in volume of 5.2 l is shown).
  1. At first measure resistance of the block of the sensor at a full fuel tank. Resistance should make about 120 Ohm.
  2. Wait almost full devastation of a tank and repeat procedure of measurement of resistance - now it should make 10 Ohm.
  3. If indications differ from stipulated above, or the full speed of a float of the sensor gives very minor change of resistance, replace pump assembly with the sensor.

In a different way checks of the fuel level sensor its removal from the car (see item 1-4) and resistance measurement 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 bottom situation) to a tank.

Replacement

 PERFORMANCE ORDER

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