Lambda Sensors

Lambda Sensors. 02 XKR 4.0Ltr convertible. 140,000Mls

I am replacing Upstream - Bank 2 / Passenger-side sensor, also decided to replace both Upstream units as I noted quite a fiddly job whilst on ramp.

Are the sensors changeable i.e. can you swop left to right, although I appreciate not upstream to downstream

As I am keeping this lovely I am now considering replacing both ‘downstream’ sensors as well, thinking will be cost-effective for 17 year old car with 140,000Mls…excellent engines!

Is there any Information of the life expectancy for these sensors..?

Appreciate your comments & observations;

“ Thanks “

Hi Clive,
Not sure about life expectancy of the Lambda sensors but I think you are wise to replace all at the same time.
Also it could confuse the ECU a little if you have one new one and three old ones but then I'm a bit eccentric like that .(keeps things all nicely balanced,IMO).
At seventeen years old your bound to get another one go if you just do the one,if your luck is anything like mine .
No difference between passenger side or drivers side.
Hope that helps a bit.
Take care.

Hello again Clive,
Not sure if you do your own work on your car but I should of said if you need a workshop manual for your XKR just PM me you email address and I will gladly send you a copy in PDF(the wonders of the modern world ).
Take care.

Lambda sensors are not dissimilar to spark plugs in that they deteriorate steadily throughout their lives. It's best to treat them in the same way and take a deep breath (when you see their cost) and for best performance, be prepared to replace them as a set once they have survived past 100,000 miles.

" Thanks " Andy & Mike
Appreciate your response, agreed I'll get the garage (I dont have the facilities/ability myself) change all 4.
Should then be good for another 100,000+

Best

Clive
