Re: 2006 X-Trail Catalytic Convert Issues Hello all
Little while since I have posted but have an update.
After doing some more research, discovered some interesting facts that I had not considered.
1. Found that O2 sensor have about 80-150K km life (dependant on brand), anything past that is awesome/lucky.
2. In my case, asked Nissan Moorooka to visually inspect the condition of both O2 sensors and Catalystic converter @ 270K km service (which I discovered they did not, mostly because when I got a mechanic to replace O2 sensors found that there was no tool marking on the sensors..... They where never inspected, maybe CC was not inspected either)... good job Nissan taking my money, shan't be taking my Trail there again...
Anyway...
- This part I really wished I took a photo's of the old sensors.
Found that the old sensors had a some sort of baked on residue that completely covered the sensors leading edge. This residue had worked it's way into the exhaust gas inlet of the sensors rendering them not working as advertised. The effective exhaust gas sampling was the aft part of the sensor, about 90 degree arc from behind. So 270 degrees was blocked off.
3. Residue may have likely come from long term use of ULP 91... The idea was thrown around...
4. 3 Months down the track after replacing O2 sensors have found the following. Wanted to get some solid numbers/performance before posting the good news
- No more pesky Malfunction Indictor Lamp (P0420 Catalyst System Efficiency Below Threshold)
- Much better fuel efficiency!! From 480-530kms a tank to 610-640kms!!
- Feel a lot more torque then what I had.
- And much better acceleration.
Huzzah!! Hope maybe this will help someone down the track that has a Trail with 150K+ km with an annoying MIL (P0420)

Re: Thanks Kenny for the post. I had P0420, I replaced the "bank 1" O2 Sensor, cleared the MLIL code, so far so good. My exxy has 180k, so going by your research info, mine was overdue for the )2 sensor (s) to be replaced.
Did you also replace the lower 02 sensor ?, if yes any chance you have the part number ?.
Cheers

Re: Anyone got a part number for the O2 sensor from a 2004 model?
Not sure how to describe my cars' symptoms but it struggles, and feels very restricted, when trying to "rev it out". Also strugglying to get better than 12.5 L/100 economy just everyday driving.
Had to replace the Manicat Friday (Installed a second hand unit as couldn't afford the 500 for new) as the exhaust mech said it was the cause of the funny noise coming from the frony. He also showed me it was starting to crack and break up inside (Viewed throught the O2 port)
Only had the car for 4 months but rwally thought the performance, on a 91k old car, would be far better.
