Lambda sensor help!

4 posts in this topic

Hi, I found out what is causing the engine managment light too come on my car, its the lambda sensor.

I was wonderin how much one of these would cost and if I could fit it my self. If so how do I do it?

Its the pre cat lambda sensor on a focus st170 54 plate

Cheers people

your looking at around £42 plus delivery from online automotive, although i would get the part number of the old one if you can and give them a call to double check. failing that have a look on ebay

you could fit this yourself, not a difficult job providing the old one comes out.

thanks mate, price doesnt sound too expensive lol, very happy with that,

but how would i remove the lambda sensor, i looked at it last night and i can unplug one end of it but the actual sensor which plugs into the cat im not too sure about, i didnt wanna force it just in case i damage the cat or something

yep i thought the price was reasonable, there are genuine ones on ebay for a whack more.

my advice would be to give it a good soak with some wd40 and leave it overnight if you can. sometimes a rag soaked with it and wrapped around the sensor may help too.

you should get away with using a 22mm ring spanner on it. if it doesnt come free then it may require some gentle heat from a blow torch.

if it does come out, a little bit of copper grease on the threads before you put it back in is a good idea. the new one doesnt need to be super tight either, just nip it up and it will be fine
