Oxygen Sensor

[svgnewbie]

Is there a way to clean an oxygen sensor, i dont wanna buy new ones cause i'm planning on getting a "new" engine in a month or two. Thx in advance.

even with the "new" engine youre gona need a new o2 sensor..

and no an o2 sensor cannot be cleaned without damaging it

They're $40-ish at RockAuto.com. Just get a new one. Your "new" engine most likely will not come with one, and if it does, it probably won't be any good.

Not even that any more. A Denso one I just checked with 1st class shipping is $32.

They are like $10 at your local pull-a-part sure there's a chance it won't work but you can take it back and get another one

just drive it like it is since ur geting a new engine only thing is ur fuel milage want be as good as it wuld if o2 wus good

Until he clogs his catalytic converter and has to replace that as well... and they're not $32.

As cb7rush said, you'll need an o2 sensor for the new engine... so get it now. Just be sure to get one that will be compatible with the new engine, as splicing o2 sensor wires doesn't always yield the best results (it can alter the resistance, causing inaccurate readings.)

Even if you find one that works, how long does that one lasts? For $22 more, it saves you the hassle of changing it again or at least you know it's new and not worry about it any more.
I saw the diagram with the o-ring before putting the O2 sensor on that must be changed. When you get the new one, does it come with that already? Or is that a washer and it's included with a new one?

Thanks.

if you really want to "clean" the o2 sensor try this.

1: remove the sensor. dont just remove the sensor. heat up around the thread area with a torch. if you dont have a torch then drive around for 20 minutes or so. get the exhaust noce and hot. shut off car and immediately go to sensor with socket and remove.

2: take sensor and spray area below threads (thats inside exhaust pipe) with carb cleaner. soak it wet with the stuff. now take the torch and apply flame to area that you just sprayed. will drip flames and posibly flare up. keep the flame on it til there is no more residue on the sensor area.

3: now spray same area as before with brake cleaner. apply flame again. again watch out for dripping flames and flare ups.

4: repeat step 2

5: repeat step 3

6: apply flame again until sensor area is red. allow to cool by air or just blow out with compressed air from air gun

7: apply anti-sieze compound to thread area on sensor and reinstall into exhaust. connect wire and drive happily until you can get a new sensor
