Greetings! Welcome to Tezzaworld website, unfortunately you are a few years late to the show as nearly everyone has been and gone, there is still lots of useful archived material to read through, not many active users unfortunately, but that’s the way it goes, hopefully you are not too disappointed...
I replaced mine last month with a universal 4 wire one. Cost €70 from local motor factor, a fraction of what they are new from Toyota. I had to cut the wires going to the original one and solder them to the new 02 sensor as universal ones don't come with the multiplug that connects into the passenger footwell. The make of it was Meat Doria. Handy enough job to do. It had 2 white wires, a black wire and a grey wire. The 2 white wires join to toyota's 2 black wires (heater wires) The black wire joined to Toyota's white wire (ground) and the Grey wire joined to Toyota's Blue wire ( signal)
Thread size is M18 & you will need a size 22 spanner or adjustable wrench to loosen old one & fit new one
Think a genuine one is about £100 from what I can remember.
Non genuine ones are ok but I have had issues with jap cars and non genuine lambda sensors. If you buy a non-gen one and it doesn't fix you're problem and that non-gen part could still be the problem but you are non the wiser. Hope you can make some sense out of that.
However my car has been doing 29mpg. Some people on here say that they get better than that. They claim to get 600km off a full tank which is 60liters of fuel. That works out to be 37mpg. Now i dont understand how they are getting that kind of mileage when Toyota themselves say that my tezz is good for 30mpg. So i thought i would try something to gather if there was a problem with my car.
I thought that an aftermarket sensor would be inexpensive and is just a plug & play. Obviously it is neither...
Lol I'm pretty sure my car has never done 38mpg, when it was n/a it did about 20mpg round town and 30mpgat a push when on a long motorway run. That's only if I was driving it fairly slow and sensible. I think it's actually a bit better now it's turbo'd, although my fuel gauge isn't very reliable now tho so I'm not completely sure.
29mpg actually sounds pretty good, especially considering you live in a warmer country too.
Part number is 89465-53070 and i got quoted 286NZD from Nick. I fitted a universal sensor last week and i dont think it works very well. As tomo said, getting a non original part can not always solve the problem. Does anyone know how much they cost in UK and where would be the best place to get one?
Good lad, i think i mite have an lambda sensor at home for one, i got a second hand manifold at the weekend and there was one win it.. the wires where snipped tho so you'd have to rejoin or solder them, i'l see if i can find it if ya want, i just used my own sensor,
as regards mpg, i was getting round 600km to a tank, but i taught it was a 55 liter tank and worked it out round the 30mpg mark... but if its 600liters i think it still works out around 28mpg..
No bother lad, its there if ya want... but i just read trough that again sounds like your getting good enough mpg.. like i worked it out from wen the light comes on, and last time i filled it it toke about 53 or 4 liters so if it is a 60 liter tank there's another gallon in it, so like its not bad..
i just wonder if it was mapped for Irish petrol would it make any difference...
