Just an update incase someone else has the same problem. I think we have found the solution. Although the upstream lambda sensor is coming up as faulty with the code P0132, the actual problem is the downstream lambda sensor. Basically, we had them both changed, but initially only the first one. After this one was changed the same problem occurred and the engine light came back on with a jittery engine. Once the rear sensor was fitted, everything was back to how it should be, so I hope it will help anyone with similar problems!

I've had similar problems too.

I've got a 2004 (54) 1.2 nissan micra which I've had since new.

Last december the amber/yellow warning light came up on the dashboard. Took it to a local garage (well know tyre and exhaust company) and a diagnostic was carried out, I was told that it was the oxygen sensor to the front of the exhaust system and it would need replaced. It cost £170 excl the diagnostic, so in total it was just short of £200.

Now less than 3 months and 1500 miles later the fault has re-appeared again!!!!

Took it back to the garage who did the work, and they've said it'll need another diagnostic to see whether to new part has failed or something else has gone!!!! Considering these sensors are supposed to last between 60 - 80 thousand miles, and I've only done 42 thousand (I only do about 6-8 thous a year mileage). The car is over 6 years old (7 this year) but this is getting beyond a joke.

The car has been regularly serviced by Nissan when it was under warranty and I get it serviced every year by another garage who I go to (they don't have the diagnostic system to carry out this work).

Could it be that the part fitted was faulty? Or could it be something else?

Does anyone have any ideas?

Had another diagnostic done tonight, and the bad news is that the other o2 sensor at the back has also gone. So that's another £200 that I've had to pay tonight. The part has been ordered but won't be in until Wednesday/Thursday. They won't order the part unless I pay for it first.

They've said that the damage to the front one has probably masked the damage done to the back one. Considering I had to wait 2 weeks for the part to arrive for the first one, hopefully this one will arrive when they've said.

So far this car has cost me £400 in 3 months!!!! Sometimes I wonder if the potholes are not helping matters. Since I noticed it on Saturday, I used a quarter of a tank for only 20 miles. I only wish I could afford a new car, but that won't happen unless I win the lottery lol.

Me and the OH have decided that we won't be buying another Micra, as it's costs too much to repair or get replacement parts.

...I'm now expecting the garage to say that it's the downstream sensor!

To follow up from my earlier post, the main dealer did indeed say that the other oxygen sensor needed changing. Apparently this was 'completely unrelated' to the upstream sensor fault, but as an engineer I do find this hard to believe.

The bottom line is that they replaced the second (downstream) sensor and the yellow warning light has not returned yet, so it does seem that the problem has been sorted.

As far as the cost goes, we managed to get the £45 'diagnostic fee' waived and also the labour charges (more of a challenge but they relented). In total an additional £150 inc VAT was paid, which is a slight discount on the cost of the sensor itself, which is apparently £142.50 + VAT.
