What's the fault code read? this should give you a clue?

a 21 or 25 would point to the sensor. Use a voltmeter on it to see if it's giving a valid reading 0 - 1 V

Yes indeed I have just changed the oxygen sensor in my 1997 carina and if you are anything like me you will have been gobsmacked at the £300+ tag on a piddly sensor. I had problems tracking down a universal replacement as finding out what engine type I had was a real pain. Eventually got the info from toyota tech team. If the sensor is on the front of the engine on the manifold its a lean burn and thats the expensive one. If its on the down pipe it could still be one of two others. I got a lot of help from a guy at lgpkits.com who advised and got me a replacement for £225 as a favour. If you engine is not lean burn you can get a replacement for about £65 from these guys. Dont buy second hand ones and finally did you reset the ecm by pulling the fuse for 30 seconds?
