Lamda sensor problem on my 172...

[wristel]

need som help... the sensor on the first pic is the sensor for the air/fuel right?

but where is the other one?

and another thing... whats the number on the right sensor?... swedish parts dealers have no idea what goes on what clio...

what year is your 172?

Most likely answer is you have a ph1 and so no post-CAT sensor. Second most likely answer, its been removed from the loom/hidden somewhere and a single sensor/bodged system fitted.

My money is on option 1

Its built october 2000.. in Sweden thats a 2001..

I'd say that's standard

 

[wristel]

Ok.. So the ph1 just have one lamda sensor then..

just one question then.. wich one is the right one for the ph1?.. or could I go with a "universal" with 2 wires?

 

[wristel]

Is it the same 4-wired sensor on all 2.0 16v from 2000 up to 2006?..

Is it the same 4-wired sensor on all 2.0 16v from 2000 up to 2006?..

same sensor. Small differences in wire length but they all fit
