Hello!

I am new to the forum and would like to help. I have a Outlander Sport 2011 and she began to fail in the second oxygen sensor. I realized exchange and has since appeared a strange noise. Does not alter the car's running, but it bothers a lot. I took the mechanic again, but found nothing.

Any suggestion? The noise is the car on the left and only appears when in D or R, just when the motor vibrates more.

Noise:

 

Hard to diagnose via youtube...but thumbs up for going that far. Almost sounds like a heats shield is loose. Not sure where you are, but some of us have shields that rust off in a few years....perhaps mechanic damaged a rusty bracket while changing the O2 sensor.
I can't think of anything else.

 

Thanks for your reply my friend.

Im in Brazil. My car was made in Japan. After the exchange of the probe, it took me back to the mechanic who did not diagnose anything. As was already there, I took and changed the oil automatic transmission. Unfortunately the noise continues.

I will investigate what you said.

Here, in Brazil, i didnt find nothign to help me a discover what is the origin of this noise. Sorry about my english.

Tks again my friend.
