removing lambda sensor

[daz the plumber]

i can`t work out how to remove a lambda sensor , the nut is to hard to get to with a spanner and i can`t get a socket over it due to the cable and connection , when i try to use a pair of grips it just squashes the sheathing .

You need either a 17mm socket slim enough to fit inside a 26mm bore and big enough to clear the sensor, or a 17mm box spanner.

To use the socket you need to cut a slot down the side to clear the cable.

To use the box spanner you need to remove the terminals from the plug (easily done by releasing the latches using a small screwdriver) leaving the rubber bung on the wires, then push the bung + wires down the inside of the box spanner. Make a note of which wire goes where in the plug so you can put them back into the plug afterwards. Of course you can use the other side as a guide as long as you don't do them both at the same time ...

I have just removed mine with a home brewed tool made from a spare spark plug box spanner that I cut a 3mm wide slot in to feed the wire through, however as the sensor was very tight I found that I needed to put a jubilee clip over the end of it to stop the spanner slipping, once I had done this it worked a treat.
I can mail you a picture of the tool if it helps.
If you are replacing your lambda sensors and if you dont want the old ones could I have the old ones please? I want a couple of the connectors to make up a test meter. Happy to pay for postage.

Good luck

I bought a 17mm long series socket from Halfrauds and used an angle grinder to form a slot down it to take the wire. No need to remove the connector.

I used a jubillee clip around the socket once the cable was threaded through in order to stop the socket flaying out at the slot.

Ditto, but i didn't need the jubillee clip

Thanks
