Replacement

Oxygen sensor (turbo engine)

Removal





Important: The electrical connector may be located either under the cover panel over the false bulkhead space or under the intake manifold.

1 Remove the cover panel.

2 Unplug the oxygen sensor connector.

3 Withdraw the oxygen sensor's leads. To do this, it may be necessary to raise the A/C pipes slightly.

4 Remove the clamps securing the oxygen sensor 5 lead to the coolant pipe.

5 Remove the clamp adjacent to the A/C compressors lower retaining bolt.

6 Remove the oxygen sensor.

Important: The leads must not be twisted. The oxygen sensor is sensitive to impacts and jolts and should therefore be handled with care.


Fitting





1 Before fitting the oxygen sensor, lubricate the threads with Molycote 1000.

2 Fit the oxygen sensor.
Tightening torque: 55 Nm (41 lb ft).

3 Fit the clamp adjacent to the A/C compressor's lower retaining bolt.

4 Press home the clamps securing the oxygen sensor's lead to the coolant pipe.

5 Introduce the oxygen sensor's leads. To do this, it may be necessary to raise the NC pipes slightly.
