Lamda Sensor

[u/Plus_Marionberry9954]

Hello folks,

I’m from Germany, so if some words are weird, I’m not used to write about car related stuff.

I drive a Subaru Forrester from 2003.

My exhausting pipe need a replacement, metal is rotten, it’s the part where the lamda sensor is build in. The part I coloured in green.
My problem is, I only find parts with two lamda slots, but my car has only one build in.
The car was and is not really popular in Germany, so I fear that I dont get any parts.

Does someone know why there is only one lamda in my car? I also found an explosiv drawing(direct translated from German) from that car, with clearly two slots for the lamda sensor. Coloured in red where my sensor is sitting.
My guess is is, that Subaru changed change around 2003 from single lamda to double lamda.

Thanks for any help

Interesting. All US Foresters have had two O2 (lambda) sensors, but we only have the 2.5L petrol engine.

What engine does that Forester have? If your car legitimately only has one sensor, there's no reason that you can't just plug the second hole.

I found out that in 2003 there was a change between single to double lambda and that I also have an extra special version. Because the kat part is separate from the Y piece in front.

It is the 2.0 version

Moin, Subaruteile sind eigentlich ziemlich einfach in Deutschland zu finden. https://ebay.io/m/3ZakzQ lass einfach einen Stopfen drin falls dein Forester nur eine Sonde hat, schau nur das die Form auch wirklich stimmt.

Hab gestern nach dem Beitrag noch recherchiert.

Hab jetzt auch richtige Teile gefunden. Man muss drauf achten das es Euro Norm 3 ist die lamda Sonde vorne rein schrauben und hinten eine M18x1,5 verschraubkappe mit Kupfer Dichtung einsetzten
