REMOVAL

I - REMOVAL PREPARATION OPERATION

  • Position the vehicle on a two-post lift.
  • Disconnect the battery.

II - OPERATION FOR REMOVAL OF PART CONCERNED

1 - Downstream temperature sensor

Exhaust

  • Remove:
    • the downstream temperature sensor insulation bolts (3) ,
    • the downstream temperature sensor insulation (4) .

Exhaust

  • Remove the bolt and the nut (5) of the downstream temperature sensor mounting.
  • Unclip the downstream temperature sensor mounting (6) .

Exhaust

  • Disconnect the particle filter downstream temperature sensor connector (7) .
  • Unclip the wiring at (8) .
  • Remove the particle filter downstream temperature sensor union (9) from its adapter welded to the particle filter.

2 - Upstream temperature sensor.

  • Remove the particle filter.

Exhaust

  • Remove the particle filter upstream temperature sensor union (10) from its adapter welded to the particle filter.

REFITTING

I - REFITTING PREPARATION OPERATION

  • Check the condition of the temperature sensor wiring.
Note: If necessary, replace the particle filter temperature sensor wiring.
  • Coat the particle filter downstream temperature sensor bolt union with COPPER-ALUMINIUM LUBRICANT.

II - REFITTING OPERATION FOR PART CONCERNED

1 - Upstream temperature sensor.

  • Refit the upstream temperature sensor to its adapter.
  • Torque tighten the particle filter upstream temperature sensor union (30 N.m).
  • Refit the particle filter.

2 - Downstream temperature sensor

  • Refit the downstream temperature sensor to its adapter.
  • Torque tighten the particle filter downstream temperature sensor union (30 N.m).
  • Connect the downstream temperature sensor connector.
  • Clip on the downstream temperature sensor wiring at (8) .
  • Refit the downstream temperature sensor mounting.
  • Torque tighten the downstream temperature sensor mounting bolt (4 N.m).
  • Refit the downstream temperature sensor insulator.
  • Torque tighten the downstream temperature sensor insulation bolts (6 N.m).

III - FINAL OPERATION.

  • Connect the battery.
  • Check that there are no faults using the Diagnostic tool.
