How to replace oxygen sensor?

[tbourner]

OK, before I go into doing this, having had so much pisstaking trouble with a bleedin' spark plug change!!! Can someone tell me what to expect from replacing the O2 sensor with a general one?

I know it's a case of cutting the 4 wires and soldering in the new sensor.


Should I expect all the wires to be the same colour? Will it break if I touch it? How does the manifold bracket go on?

Most importantly where the hell is the sensor!!!!! Anyone got a pic handy?

If you touch the wrong bit you will be dead in 30 seconds !!!!:eek:

No scaring people in Technical - be helpful :p

Wire colours - probably different
Don't drop the sensor but apart from that you are OK
It's two 12mm nuts so an absolute piece of piss to do and get this - you can get at them without dismantling anything else :eek: The sensor is on the exhaust downpipe, driver's side of engine bay, follow the one sleeved cable heading in that direction :)

And have a decent socket set cause the nuts will be tight to the last thread !!!!

Sorry guys, Im pretty sure the sensor, doesnt require any soldering, just follow the cable, itll be pinned down near the strut, with a harness connector?

So, just unclip it, and clip a new one in.

HTH,

New off-the-shelf narrowband O2 sensors don't have the Toyota connector on the end :)

Actually, the generic O2 sensors have a screw thread body whereas the Toyota ones are welded into a flange - I know Chris Wilson sells O2 sensors with the correct flange for the sensor to screw into, may be worth talking to him, I think his price is rather good too.

That's if you haven't got one already :)

I ordered one from the US, with a screw in flange, and harness on it already.

Ill find out more.

Getting mine from TRL.

Pete's giving me the correct bracket as well, I'm sure all will become clear when I get it!!!
