6.4.2.7. System of decrease in toxicity of exhausts

MODELS WITH THE CARBURETTOR ENGINE

Check

PERFORMANCE ORDER
1. Adjust structure of a fuel mix for an idling mode (level WITH) (subsection 2.2.2 see).
2. Uncover the block of safety locks for access reception to a socket of diagnostics which is established from below the block of safety locks.
3. Establish a tester on measurement pressure and connect it щупы to a control socket of the block of safety locks how it is shown in drawing.
4. Start the engine, lift speed of work of the engine approximately to 2000 rpm and keep it at such level approximately within 2 minutes, watching a tester scale. If the gauge of exhaust gases works correctly tester indications should change about 0 Volt to approximately 12 Volt at least 5 times each 10 seconds. If is not present, possibly, the gauge is faulty. For carrying out of more detailed check of the gauge and каталитического the converter address to experts.

MODELS WITH FUEL INJECTION

Check

If WITH in exhaust gases too high, work of the gauge of exhaust gases it is necessary to check up level, having included the electronic block of management of the engine in a self-diagnostics mode (subsection 6.2.11 see).

For carrying out of more detailed check of the gauge and каталитического the converter address to experts.

THE GAUGE OF EXHAUST GASES

The prevention

The gauge of exhaust gases is very fragile and will fail, if it to strike or drop, if during its work to disconnect a food, or at hit on it of any cleaners.


Replacement

PERFORMANCE ORDER
1. On models with the engine in volume of 1,6 litres, walk along wires from the gauge of exhaust gases which is twisted in a final collector. Disconnect a socket of connection and get wires from all fixing clips.
2. On models with the engine in volume of 2,0 litres put the car on a manual brake, lift a forward part of the car and establish it on support. Walk along wires from the gauge of exhaust gases (which it is twisted in a reception pipe), getting wires from all fixing clips.
3. Disconnect a connection socket.
4. Unscrew the gauge and remove it together with a sealing washer.
5. Installation is spent upside-down removals. At installation use a new sealing washer. Before gauge installation grease a carving of the gauge with high-temperature greasing. Reliably twirl the gauge. Check up, that wires have been correctly laid and did not concern exhaust system or engine pipes.
