Oxygen Sensor Removal Tool Needed .

[discopotato03]

Hi all , need to be able to remove the 02 probe from my S2 R33 GTST and having had the heatshield out twice I think it's obvious that the only way is with a dedicated socket .

Can anyone suggest a brand of socket known to work on these cars .

Cheers A .

Ive got one you can have for $40 posted obviously only been used once

When I replaced my O2 sensor, I cut the top off and put a standard socket on it.

i used a pipe spanner...but you may not have room

I bought a long socket in the right size then put a hole in the side of it with a dremel for the plug to fit through... worked well

I don't want to destroy it , just remove it so a wide band can be used for tuning occasionally .

obviously it has to be long enough to seat properly on the hexagon but not so long that I can't get a square drive into it or a suitably sized spaniard if it has a hex on the top of it .

Also for some stupid reason I can't find any Snap On dealers contact numbers online for Southern Sydney .

I drove past the local truck this morning but had other places to be at the time .

Snap on Eddie - where are you !!!

Cheers Adrian .

Quick update , going to see George at Aus Tools Dulwich hill tomorrow .

He does a T&E branded 22mm oxygen sensor socket (2-7231) which has the hex on top for ~ $25 .

He's going to let me do a trial fit so I'll know if it'll work .

Cheers Adrian .

why not stick the wideband inside the exhaust tip ? I'm pretty sure that's what most tuners do when tuning ..well from what I've seen anyway.

But on 2nd thoughts, that does bring an interesting question to mind .. just how accurate are the readings from the tailpipe vs dump pipe. After all the gases coming out of tail pipe have already been filtered by the catalytic converter. HMM!

i changed nine as it had done over 40,000km. used 22mm (or 7/8") from KC tools it only just fit tho and i had to cut the old wires off..

also needed a f**king strong power bar as mine had been in for a good 110,000km... was time for a replacement!!!

a good tube socket would work BUT im guessing you wont be able to get the plug from the wires thru the centre..

i took mine off in less than 5 min.

i cut thru the metal bit on the outer shell & then used a long screw driver & hammer to smash thru the

ceramic centre. Once that was done any regular 22mm socket would fit.

The o2 sensor shouldn't be done up super tight. They only need to be hand tight + a 1/4 or 1/2 turn or something. But I got mine off by using 2 spanners (lol) one angled onto the sensor as best as i could get cuz of the tight space, then use an adjustable spanner on the first spanner to lever it around and undo the sensor. easy

thought i would post an update on before & after O2 sensor install.

with old o2 sensor :

* idle was a bit rough

* engine was running very rich with shocking fuel consumption.

after new universal o2 sensor

*idling perfectly in cold & warm

*fuel has leaned out & im very happy with the new fuel consumption.

* feels like there's a power gain, not sure though without a dyno test

it's all in your head mate. o2 sensor only comes into play on light load eg. cruising.

when giving it the berries the o2 sensor has zero effect.
