Konrad Posted June 5, 2008 Share Posted June 5, 2008 Quick guide to take off lambda sensors from NA for those, who think their cars are using too much fuel and it would be worth to clean them, but they need full walkthrough . I did it on my white Supra and she is moving now like she would loose around 300 kg. This one was done on my garage sleeping beauty, Pink lady Time: 15 minutes Tools: Philips screwdriver, 12mm socket on ratchet. Take off air induction pipe by loosening screws and them twist it slightly. Unclip and disconnect those 2 small rubber pipes. Screws on heat shield and O2 sensors screws soak with penetration oil. It is possible, that all bolt will come out, do not worry Unscrew O2 sensors and disconnect them. Put them into lemon juice for a night, after that clean them with brake cleaner (I use foam one so all crap is getting out when foam is expanding), dry using pressurized air for example. Put back everything and have fun Konrad. Quote Link to comment Share on other sites More sharing options...

gordy07 Posted June 5, 2008 Share Posted June 5, 2008 Are both sensors the same ie does it matter if you get them mixed up Not that im going to i was just wondering:) Quote Link to comment Share on other sites More sharing options...
TurboBrett Posted June 5, 2008 Share Posted June 5, 2008 (edited) been considering doing this for ages, is there any chance of breaking the o2 sensor? Edited June 5, 2008 by TurboBrett (see edit history) Quote Link to comment Share on other sites More sharing options...
Konrad Posted June 5, 2008 Author Share Posted June 5, 2008 Are both sensors the same ie does it matter if you get them mixed up Not that im going to i was just wondering:) Yes, both sensors are identical been considering doing this for ages, is there any chance of breaking the o2 sensor? No, those sensors are quite sturdy piece of metal Just soak all screws with penetration oil or Gas Plus oil to loosen them a little before unscrewing Quote Link to comment Share on other sites More sharing options...
Konrad Posted June 5, 2008 Author Share Posted June 5, 2008 Does it have to be LIDL ketchup? It's proper Pudliszki ketchup, not cheap Lidl mark! Quote Link to comment Share on other sites More sharing options...
Nic Posted June 6, 2008 Share Posted June 6, 2008 Good guide Konrad Cleaning the O2 sensors is only usually a short term fix, if you want to do the job properly fit brand new ones. Not cheap, but with the price of fuel as it is, it is a very good investment that will pay for itself in no time. Quote Link to comment Share on other sites More sharing options...
Missile Posted April 21, 2011 Share Posted April 21, 2011 (edited) Right - Mr Konrad, I have bitten the bullet and gone for it. It's taken almost a year to get round to actually doing them. But Last year the trip to Japfest and back cost over £100 in fuel. The year before that was way less. So Lemon juice - Playboy shot glasses at the ready... They have been in Lemon since last night. So popping home at lunch to remove them. Will post results GOOD - BAD after re-fit. Just need to get some Brake cleaner. Cheers Konrad.

Havard Posted April 21, 2011 Share Posted April 21, 2011 I need to look into mine on the TT where there is only one sensor. Where does the wire at the other end attach to? Are there just clips near the manifold.? I will go outside and have a look at some point but the car is undercover at the moment. H. Quote Link to comment Share on other sites More sharing options...

The other is just of Konrads pic. I'm betting the clips look simular. Quote Link to comment Share on other sites More sharing options...
Nic Posted April 21, 2011 Share Posted April 21, 2011 Will post results GOOD - BAD after re-fit. Just need to get some Brake cleaner. Cleaning them tends only to make a short term difference - if at all - if they need replacing, would be good if you could post long term results. The 2 x 2JZ-GE sensors are identical, so doesn't really matter which way round they go back. Quote Link to comment Share on other sites More sharing options...

The 2 x 2JZ-GE sensors are identical, so doesn't really matter which way round they go back. I will certainly update. Really am hoping for a difference. I was paranoid so decided I would put them back in as I took them out. I keep getting close to doing the NA - TT swap. Just can't justify spending out on new ones if it's only a short while, saying that, if I'd bought them a year ago they would have paid for themselves but now.

Yeah price of fuel as it is, you could have fitted new ones, done your TT conversion and still have saved money Quote Link to comment Share on other sites More sharing options...

Missile Posted April 25, 2011 Share Posted April 25, 2011 Update... Fuel is lasting longer so great news. But performace has only incresed a little, but saying that it pulls after 5k much harder than it has been. Like it did when I first bought it.

Supra Gaz Posted April 25, 2011 Share Posted April 25, 2011 I will be doing this, seems to be a sensible easy bit of maintenance, how much are new sensors anyway? Quote Link to comment Share on other sites More sharing options...

Found these. The plug looks the same and the unit looks the same? Quote Link to comment Share on other sites More sharing options...
t-one234 Posted May 8, 2011 Share Posted May 8, 2011 ive just taken mine out and they are cleaning also did some research on new o2 sensors the code for denso OEM style sensors is 234-1055 they are coming up at $50 dollars each abroad so im guessing about £30 sterling Quote Link to comment Share on other sites More sharing options...
