2.6.15. Removal and installation a lambda probe after the catalyst

Removal

Fig. 2.252. Shtekerny connections for a lambda probe and heating a lambda probe


Disunite electric shtekerny connection 2 (the brown plug) for a lambda probe after the catalyst (fig. 2.252).

Fig. 2.253. Location lambda probe and heating lambda probe


Unscrew a lambda probe after the catalyst 1 by means of the tool from a set of cap keys for a lambda probe (fig. 2.253).

Installation
The electrical wiring a lambda probe has to be surely fixed on the former installation sites to avoid contact of an electrical wiring with an exhaust pipe.
Inhaling moment: 55 N · m.

NOTE
New a lambda probes are greased with adjusting paste; hit of paste on probe case grooves is not allowed.
When using being in the use a lambda probe it is allowed to grease with heat-resistant paste only a carving. Hit of this paste on probe case grooves is not allowed.
