How to replace oxygen sensor?

Recommended Posts

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?

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 :)

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 :)
