Removal and installation of the sensor of oxygen

At the BMW car of the 3rd series sensors of oxygen are located before and after the catalytic converter to provide control of purity of the fulfilled gases.

Connecting cables of sensors of oxygen are not under repair and are not soldered. In the presence of damages the cable is replaced in a set.


 REMOVAL

Lifting operation and installations of the car on supports is connected with danger! Therefore before carrying out operation study Poddomkrachivaniye's Section and towage

1 Lift and install the car on supports.
2 Models 316i, 318i: The oxygen sensor socket-3 also turn out Rasstykuyta the sensor-4-of a reception pipe.

3 Models 320i, 323i, 328i: Rasstykuyte shtekerny connections of sensors of oxygen (two arrows on the right on an illustration).

Mark plugs not to mix them at assembly. Uncover the engine to open plugs, address to the Section Removal and installation of the lower cover of a motive compartment.

4 Disconnect the holder of a cable (the left arrow). Turn out oxygen sensors from a reception pipe. The cap key, for example, of HAZET 468/4 is for this purpose necessary.


 INSTALLATION

Do not clear the oxygen sensor around top and do not allow contact with greasing. When drawing a sheeting on the bottom close sensors.

5 Cover an oxygen sensor carving with special high-temperature greasing "Nevar seez Compound".

If the sensor of oxygen is rolled without high-temperature greasing, the carving burns over time and the sensor cannot be turned out. New sensors have the corresponding covering.

6 Screw the oxygen sensor in a reception pipe and tighten the moment 55 N • m.
7 Lay an electric wire so that it did not fray and did not concern system of release.
8 Establish an engine cover.
