Can sommeone tell me were is that sensor and how can I verify it?

 

Thanks

Assuming it's the same as my Loyale - open the hood. stand on the passenger side. look behind the engine, and running down the side of the transmission you'll see a wire that runs down to below everything, ending at the O2 sensor at the exhaust Y/cat.

 

Don't remember the test, but if you don't know how old it is, it probably needs replaced. Inexpensive preventive maintenance.

O2 sensors are always in the first section of exhaust pipe

I don't thing I have O2 sensor:-\....is this possible?

 

Should I look with more attention?

 

Thanks.
