Nissan X-Trail T30 Oxygen O2 Sensor

Replacing the O2 oxygen sensor on my xtrail t30. I haven't explained in the video how I came up replacing the O2 sensor because I forgot to filmed it while doing the diagnosis. Before I change the sensor I make sure all the wirings are in good condition. I had checked the sensor itself by doing continuity test and its within range but suprisingly the actual performance test was failed while using the scanner. So, I ended up replacing the sensor.

G'day mate. thanks for the video. were there any symptoms in the way the car ran with the old sensor in? I don't have a code checker and am trying to trouble shoot. basically I have a very rough idle but only when the car is at operating temperature. it's fine when cold

Sounds like you may have a failed either spark plug or ignition coil. Just a guess
