Lambda/Oxygen sensors - Can they be cleaned?
Discussion
Been looking for good price on Lambda sensors, came across this guys site on Ebay
He reckeons he can clean them using ultrasonic waves, etc & they will back to their best.
(assuming heating element is ok)
He has loads of positive Feedback(100%) & for £10 plus postage I'm tempted to give it a go
Anyone used this guy or had them cleaned elsewhere, does it really work?

Thats also what I thought....
I wonder why the switch becomes lazy though, is it because it becomes furred up or something?
Its an electrical component in a very very harsh enviroment,price/quality also come into the equation like most things it as a lifespan/cycles limitation,bloody hell some long words their,must of swallowed the English dictionaryI wonder why the switch becomes lazy though, is it because it becomes furred up or something?
Spend will slaughter me if he reads this one

I wouldn't be at all optimistic about your chances of cleaning a lambda sensor. Of course, if you send him one that's basically OK and he brushes the soot off the outside and sends it back, it'll still be basically OK. Would that be enough to persuade you to leave positive feedback?
Thats a good point Peter,like it
Just brushes the soot off, I hope not (:
This guy is an aircraft engineer & seems to know what he's talking about
The Sensors get a chemical clean & are cleaned internally by ultrasound apparently
Have emailed him & he reckons he has 100% success rate as long as the heater part is ok
Don't know whether to give it a go........

It might be worth it, but i know how crucial they are to get the engine running right. I would personaly buy new ones as they get affected by temperature and the harsh conditions.
I have a (AFR) Air Fuel Ratio wideband kit for another car i have as im currently tuning it. It has a calibration button on the control unit as after a while the lamba sensor can go out of calibration. The calibration button sets it back to open air.
If you want to get them cheaper look up the part no and order them from america. I did this on my last TVR Chimaera and saved quite abit. I think it only cost me about £45ish delivered. Ill try and dig out the link. It was 3 years ago though. There is a few posts on here about ordering the lambda sensors from america.

Excuse my ignorance but what do the lambda/oxygen sensors do and how would you know if you needed to repair/replace them?
It's a sensor attached to the exhausts (just before the Y-piece) which measures the concentration of oxygen in the exhaust gasses. It sends its readings to the ECU to allow it to adjust the fuel/air mix accordingly.I guess if your sensors weren't working properly, you'd start running lean or rich, pinking must be a risk and could you could also end up fecking up your cat.

You truly are the fountain.
Have found some very cheap ones in the US which are universal type (wires need joining), but are NTK which are supposed to be the best make.
I am an Electrician though, so not a problem.
According to NTK the only difference is they don't come with the plug on, the sensor is exactly the same as the direct fit.
Will let you all know how I get on with them (when they arrive).
They were very cheap, so fingers crossed they end up being the right ones!
(£35 inc P&P for 2)

Talking of generic sensors- can some one confirm the correct voltage for the origional units. The Rover manuals state 0-1v and the RPI site states 5 volt for the 14CUX ? Was there a change in the 14CUX in its history, or have RPI got it wrong and the 5 volt units are for the latter Sajem ECU fitted to the Range Rovers ?
Well they arrived from US, they are the right size, 12mm thread, 17mm socket size
They are 3-wire, Titania, NTK (written on packet).
They do have Nissan written on them, but I believe some old Nissans use the same sensor
Haven't got a socket to remove the old ones at the moment, will probably have to make one out of a deep reach 17mm socket as I can't find anyone who makes the correct tool
Bargain if they work (£35 for the two, including postage from the US)

Hi
I am interested to know if you managed to replace the Lambda sensors, and of course did they work okay? My 450 has just failed miserably on emissions at the MOT test, so I have been looking for ideas at to what the problem might be. Reading some of the threads here I'm thinking it might be the Lambda Sensors.

Yep, got them from the US in about a week
They are NTK easy to change with a spark plug spanner (there are differnt sizes)
Been in for over a year now & all is good, just passed an MOT on emissions for the 2nd year running
Exchange rate is so good at the moment that you ll probably get 2 for about £30
I wouldn't bother changing just the duff 1, for that money you might as well change both IMHO
