Emission control system

Models with the carburettor engine

Check

PERFORMANCE ORDER

1. Adjust the composition of the fuel mixture for idling (CO level) (see. Subsection 2.2.2).
2. Remove the fuse box cover to access the diagnostic connector, which is mounted below the fuse box.
	3. Set the tester to measure voltage and connect the probes to the test fuse terminal block as shown in the figure.
4. Start the engine, lift the engine speed to approximately 2000 rev / min and hold at that level for about 2 minutes, keeping an eye on the scale of the tester. If the exhaust gas sensor is working properly, the tester readings have varied from 0 volts to about 12 volts at least 5 times every 10 seconds. If not likely faulty sensor. For a more detailed inspection of the sensor and the catalytic converter, refer to specialists.

MODELS WITH FUEL INJECTION

Check

If the level of CO in the exhaust gas is too high, the work of the exhaust gas sensor should be checked, including electronic engine control unit in the self-test mode (see. Subsection 6.2.11).

For a more detailed inspection of the sensor and the catalytic converter, refer to specialists.

Exhaust gas sensor

A warning

Exhaust gas sensor is very fragile and will fail if it is hit or dropped, if during operation turn the power off, or in contact with him of any cleaning agents.

Replacement

PERFORMANCE ORDER

	1. On models with engine capacity of 1.6 liters, walk along the wires from the exhaust gas sensor, which is screwed into the exhaust manifold. Disconnect plug connection and remove all wires from the mounting clamps.
	2. On models with engine capacity of 2.0 liters put the car on a manual brake, lift the front of the car and establish it on support. Walk along the wires from the exhaust gas sensor (which is screwed into the exhaust pipe), pulling wires out of the mounting clamps.
	3. Disconnect a connection socket.
	4. Remove the sensor and remove it along with the sealing washer.
5. Installation is spent upside-down removals. At installation use a new sealing washer. Before installing the sensor probe, lubricate the threads with high temperature grease. Firmly tighten the sensor. Make sure the wires are correctly routed and do not touch the exhaust pipe or engine.
