Renault Clio: Particle filter pressure sensor: Removal - Refitting

K9K, and 772

The pressure measurement circuit must only ever be opened at the adapters on the exhaust pipe.

REMOVAL

I - REMOVAL PREPARATION OPERATION

• Position the vehicle on a two-post lift (see Vehicle: Towing and lifting) (MR 392, 02, Lifting equipment).
• Disconnect the battery (see Battery: Removal - Refitting) (MR 392, 80A, Battery).
• Remove:
  • the engine cover,
  • the engine undertray.

II - OPERATION FOR REMOVAL OF PART CONCERNED

• Remove the upstream pressure measurement connection (1) from its adapter (2) bolted to the exhaust pipe.

WARNING

When the pressure measurement connection is removed, the adapter must be held with a lock spanner.

• Remove the clips (3) from the heat shield.

• Remove the downstream pressure measurement connection (4) from its adapter (5) bolted onto the exhaust pipe.

WARNING

When the pressure measurement connection is removed, the adapter must be held with a lock spanner.

• Detach the downstream pressure measurement connection from the heat shield.
• Remove:
  • the pressure sensor nut on the steering box,
  • the pressure sensor equipped with its upstream and downstream pressure measurement connections.

REFITTING

I - REFITTING PREPARATION OPERATION

WARNING

Always replace any adapter that has been removed from the exhaust pipe.

• In the event of replacement, torque tighten the adapter (44 N.m).
• Coat the temperature sensor threading with ANTISEIZE COPPER GREASE or COPPER-ALUMINIUM LUBRICANT.

WARNING

Make sure that the grease does not run over the threading.

II - REFITTING OPERATION FOR PART CONCERNED

• Refit:
  • the pressure sensor equipped with its upstream and downstream pressure measurement connections.
  • the pressure sensor nut.
• Clip the downstream pressure measurement connection on the heat shield.

• Refit the downstream pressure measurement connection bolted to the exhaust pipe, observing an angle of +3
