Check of serviceability of a functioning / state and replacement of components of systems of decrease in toxicity of the fulfilled gases

Petrol models

System of ventilation of a case

Components of system of ventilation do not need service, except for regular check of a condition of hoses.

System of catching of fuel evaporations

Check

PERFORMANCE ORDER

1. Disconnect hoses from a coal adsorber and the valve of its purge and, by blowing off, make sure of their passability. Defective adsorber and the valve of a purge are subject to replacement.

Replacement of a coal adsorber

PERFORMANCE ORDER

1. The coal adsorber is behind a radiator and is fixed on the left wall of a motive compartment.
2. Mark two hoses and disconnect them from the top part of an adsorber. If for fastening of hoses collars of the twisted type are used, at assembly they will be reasonable to be replaced more practical screw or worm. If hoses fasten by means of sockets of bystry undocking, wring out the central plugs of sockets the small screw-driver with a flat sting and remove step from unions.
3. Give fixing nuts and remove an adsorber from the basic arm. In case of need to an otboltita also remove an arm.
4. Installation is made upside-down. Track correctness of connection and reliability of fastening of hoses.

Replacement of the valve of a purge of an adsorber

PERFORMANCE ORDER

1. The valve is fixed on the left wall of a motive compartment, behind a coal adsorber.
2. Disconnect a negative wire from the battery. Release a clamp and disconnect an electrical wiring from the adsorber purge valve.
3. Disconnect hoses from both parties of the valve and release the last from the fixing collar. Take the purge valve from a motive compartment. 4. Installation is made upside-down. Track correctness of an arrangement of the valve and reliability of fastening of hoses to it.

Catalytic converter and l-probe

Check

Efficiency of functioning of the catalytic converter can be checked only by definition of composition of the fulfilled gases by means of carefully calibrated gas analyzer (address the Head Routine maintenance).

If contents level WITH on a cut of an exhaust pipe exceeds admissible value, the car should be driven away on car repair shop for performing full diagnostics of systems of injection of fuel and ignition. If during such diagnostics any violations do not manage to be revealed, replace the catalytic converter (see System of production of the fulfilled gases - the general information, removal and installation).

Replacement of the catalytic converter

See System of production of the fulfilled gases - the general information, removal and installation.

Replacement of the l-probe

The oxygen sensor is among fragile electronic elements. Do not shake the l-probe and do not drop it. The break of food or use for cleaning of the sensor of chemical means can also lead to a l-probe exit out of operation.

PERFORMANCE ORDER

1. Walk on an electrical wiring from the l-probe screwed in a reception pipe of system of production of the fulfilled gases to the top part of a case of transmission. Disunite both the electric socket and release an electrical wiring from intermediate clamps and bindings.
2. Turn out the sensor from a reception pipe. Also remove it together a sealing washer.
3. Installation is made upside-down. Do not forget to replace a sealing washer. Before installation grease a carving part of the sensor with high-temperature lubricant. Track reliability of tightening of the sensor and correctness of laying of its electrical wiring (wires should not adjoin in the heated surfaces of system of production of the fulfilled gases and the engine).

Diesel models

System of ventilation of a case

Components of system of ventilation do not need service, except for regular check of a condition of hoses.

Catalytic converter

Check

If there are doubts in serviceability of functioning of the catalytic converter, before make sure of serviceability of nozzles. More detailed information can be obtained at experts company service centers of the Citroyon company.

Replacement

See System of production of the fulfilled gases - the general information, removal and installation.

System of recirculation of the fulfilled gases (EGR)

Check

Performance of check of serviceability of functioning of the EGR system should be charged to specialists of car repair shop.

Replacement of components

At the time of drawing up the present manual information on replacement of components of the EGR system was absent.

System of compensation of changes of atmospheric pressure

Check

Performance of check of serviceability of functioning of this system also should be charged to specialists of car repair shop.

Replacement of components

Detailed information on replacement of the sensor of temperature of cooling liquid is provided in the Head of the Cooling system, heating.

Information on replacement of the block of the relay/timer of system of preheat see in the section System of Preheat - diesel models.

At the time of drawing up the present manual information on replacement of the sensor switch of atmospheric pressure was absent.
