Removal of lambda sensor ...

What tool do i need to remove the lambda sensor and is the o/s the same as the n/s ?

You can buy special sockets for them.. same tool for both sides.

Will Partco or Halfords sell them ? Is the sensor the same on both side (need to order one ?)

You might struggle to find the 17mm lambda socket.Many of us have cut a slot in a deep 17mm socket instead.When i did mine it cost £3.50 from my local motorfactor,and about 10 mins with a cutting disc

Socket ? How do you get it over the wires ??

I think that's what the slot is for...

By cutting a slot in it?

...hence the slot!
The "proper" ones are impact wrench grade to try and cope with the force twisting the lambdas off, the standard ones with a slot in them can shatter if you get a particularly tough one to remove.

Sorry Mongoose just read your reply again and I understand what you mean now .... you have cut down the side of the deep socket to make room for the wires ...... yes ?

,i used a litle penetrating oil to help free the sensors also.This didn't harm them,but helped them come out easily

Just one more tip,when you cut the slot in the socket,make sure you de-burr the inner and outer edges of the slot,so as to stop you chaffing the sensor wires.

Thanks everyone.

I just use an ordinary common or garden box spanner, take the wires out of the plug and push them down the middle of the spanner. Takes an extra couple of minutes, but it's not something you need to do very often.

Mine have been in and out a few times just using an un-slotted 17mm deep socket. Dismantle the plug on the end of the Lambda cable and thread through the socket, then use a set of grips on the socket to undo. I did have to file a couple of 'flats' onto the outside of the socket for one which was very tight, but it saved cutting a slot in the socket...
