2.6.15. Removal and installation a ljambda-probe after the catalyst

Removal

Fig. 2.252. Shtekernye connections for a ljambda-probe and heating of a ljambda-probe


Disunite electric штекерное connection 2 (the brown tip) for a ljambda-probe after the catalyst (fig. 2.252).

Fig. 2.253. A site of a ljambda-probe and heating of a ljambda-probe


Unscrew a ljambda-probe after the catalyst 1 by means of the tool from the complete set накидных keys for a ljambda-probe (fig. 2.253).

Installation
Ljambda-probe electroconducting should be necessarily fixed on the former installation sites to avoid contact of electroconducting with an exhaust pipe.
The inhaling moment: 55 Нм.

THE NOTE
New ljambda-probes are greased by adjusting paste; paste hit on grooves of the case of a probe is not supposed.
At use of the ljambda-probe which was in the use it is authorised to grease with heat-resistant paste only a carving. Hit of this paste on grooves of the case of a probe is not supposed.
