2.28. Replacement of the sensor of concentration of oxygen

PREVENTIONS
Be careful during the work with the sensitive sensor of concentration of oxygen to exclude its damage.
The flexible wire and the socket which cannot be removed from the sensor are attached to the sensor of concentration of oxygen. Damage or removal of a flexible wire or the socket can adversely affect its work.
It is necessary to delete lubricant, dirt and so forth from the electric socket and an end face of the sensor.
When cleaning the sensor of concentration of oxygen it is impossible to use solvents.
Handle the sensor accurately.
The casing from kremniyorganichesky connection should be established in the correct situation to exclude its oplavleniye and violation of the correct functioning of the sensor.

The sensor is installed in a final collector, access to it is possible from a motor compartment.
As it is difficult to remove the sensor of concentration of oxygen from the cold engine, warm up the engine up to the temperature of 48 °C.
Disconnect the socket from the sensor of concentration of oxygen.
Mark the provision of a casing from kremniyorganichesky connection and accurately turn out the sensor of concentration of oxygen from a final collector. Examine the sensor on lack of traces of damage.
At removal of the sensor it is possible to use special structure for simplification of an otvorachivaniye by drawing it on a sensor carving. On a carving of the new sensor this structure is already put, but if for any reason the sensor of concentration of oxygen is removed, and then repeatedly is established, before repeated installation the carving should be covered with such structure.
Screw the sensor and reliably tighten it.
Connect the electric socket.
