1995 850 GLT 2,5 L 20S Lambdas sensors

Hy Buddies,

I'm ready to install my 2 BOSCH brand new lambdas sensors on my 850. Problem : i have only one installed on my exhaust line, and there's nothing behind the catalytic to accept the second sensor...

If lambdas sensors were begun to be installed after 1993, it means that my catalytic doesn't fit to my car. So then, i didn't see any second plug in the engine bay.

The volvo board shows that the rear one is connected to the front one ?

3.2 L.H Jetronic management should have only one...before cat.

There are two different types...zirconia vs.titania.

The ones which are for m4.4. cars doesn't work in Jetronic cars and vice versa.

You should have EXACTLY the same o2 sensor which was originally fitted to your car...with EXACTLY the same Bosch numbers on it.
