2. Temperature sensor downstream of the particle filter

REFITTING

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

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

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

• 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.

• 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.

• 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.
