This vehicle started this problem after the exhaust system was repaired and it happened that the technician cutoff the exhaust pipe o2 sensor location together with the sensor. When I diagnose, I didn't see the fault code on the O2 sensor, I used live data to read the parameter and it showed not supported by vehicle, at this point I check and notice the sensor was not there. Please I need the complete exhaust diagram to see the sensor location and I will put it back. thanks

Try this one: Black smoke is usually running very rich and can cause a converter failure if equipped. This shows both versions of that system, one for unleaded ethanol and one for other fuels. The arrows point to where the O2 sensors should be.

That vehicle isn't covered in our service information because it was not sold in the US or Canada, however this site has a possible manual that should cover it. At least it claims to be for that car, and I downloaded it and it seems to cover various versions with electrical data. It should give you some direction but I would verify the actual wiring against what your car has.
