02 Sensors For 33 Gtr

[Pal]

not sure on that one snoz, the zirconia needs heating to work properly (the two white wires are for heating)but not sure on the titania.

checked my fuel usage and ive hit 190km on half a tank. looks like the dirty afm's could have been a big contributor to the poor fuel economy. should get the new o2 sensors next week, i'll fit them next and see how that goes

Tunes not going to make a huge difference as I doubt nothing mechanically has changed requiring different fuel and ignition loads. Could removing from fuel from the tune by they generally run lean then shift AFM drops when acceleration occurs, so could get some better fuel economy, but I bet it's something like AFM, o2 ect. I've got a set here that are used, but worked fine previously Eric.

They work like a thermocouple (from my understanding), which means they would read different because of the two different types of materials.

Thanks clint, as i said, got a new set of o2 sensors coming next week, and i will keep a eye on the afm's. if there is any problems with them. 'll come and see you.

are you back from holidays yet? still got to get that price for a set of front rotors off you.

Sure dude, I'll shoot you a pm.

ok makes sense.. but is the difference in material a longetivity thing or do they operate differently due to the difference in material?

operate differently and are not compatible with each other afaik

just fitted the new o2 sensors. had to buy a special socket to get the sensor out (rare as rocking horse poop too). will see if this makes a difference.

If anybody needs to change there o2 sensors and is SOR im quite happy to help as the socket makes it very easy.

if u bought o2 that are RB25 compatible, couldnt u just get the ford EF o2 sensor from repco, as it mentions in the general maintainence section that that is compatable with the RB25, i did that and im sure it was under $100 for it, plus some connectors, and no special tool required,

a bit late now, but might help someone else that is looking thru this thread

I got the o2 sensors for $77each, Gtr sensors are alot harder to get at than the gtst so it was easier to get the correct tool for the job

So how did it go Eric? Noticed any difference?

I really need to replace mine lol.

got the fuel economy down to 13.8l/100 without the tune highway/city driving. o2 sensors are working perfectly (pfc sensor check screen). was hoping for a tune by now but other things have come up so it keeps getting put off. knocked up a catch can at work and that is now fitted so hopefully no more oil on the afm's.
