Cubes Posted January 31, 2006 Share Posted January 31, 2006 I replaced my o2 sensor with a genuine item. Around the same time fuel economy went really bad ~350-380km's to a tank, at times I felt what felt like 1/4 throttle travel flat spots not to mention the really hard cold starts. :S However, I had been having cold stumbling starts for a while prior. I ripped the injectors out and noticed a couple of the pintles were seated at different heights. Dropped GTR injectors in, trimmed the injectors by 58.5% in order to get them to drop in to closed loop mode. Initial drive... 130km's to a tank, 250km's by half... Looks like economy is back, rb30det. Link to comment https://www.sau.com.au/forums/topic/43095-o2-sensor/page/9/#findComment-1913695 Share on other sites More sharing options...
GTAHH Posted February 1, 2006 Share Posted February 1, 2006 (edited) Does the EL sensor work or not? Who has actually installed the sensor and it is working? I need an O2 sensor I have a RB20DET, and in desperate need of a sensor. The direct fit EL OX-207 is the go?

Col-GTSX Posted February 1, 2006 Share Posted February 1, 2006 Yes the EL sensor works... Did mine weeks ago and found it to be fine... Dont bother soldering just crimp the wires... Apart from that its all good... Link to comment https://www.sau.com.au/forums/topic/43095-o2-sensor/page/9/#findComment-1916046 Share on other sites More sharing options...

RANDY Posted February 1, 2006 Share Posted February 1, 2006 Nick, don't forget that the bottom of the tank is a bit smaller, so you'll go through the bottom half quicker than the top. I made the mistake of thinking "wow! I've fixed it!" when I got 100 in the first quarter of a tank. I filled on 350km exactly last night. Putting the stock BOV back on doesn't seem to have fixed anything other than getting rid of that noisy "woosh" noise that makes police and old people look at me funny.

Cooper Posted February 2, 2006 Share Posted February 2, 2006 I have read through most of this tread, there seems to be hardly any info on the R33 GTR. How hard are they to get to? Is it any easy DIY job or should i get a mechanic etc to do it? Does it entail taking the exhaust out or turbos in a GTR since there i limited room around and behind the turbos? Any help will be appreciated Link to comment https://www.sau.com.au/forums/topic/43095-o2-sensor/page/9/#findComment-1919129 Share on other sites More sharing options...
Duncan Posted February 2, 2006 Share Posted February 2, 2006 Actually it has been a PITA finding ones for the 33 GTR. They are 3 wire, 18mm thread titania ones. ACA don't have a part that will fit (ie ROX203 nor ROX207 are right). Let me know if you have any luck finding another alternative. And, the rear one is a real pain to remove while the motor is in the car....not impossible but you will need a very short flare style spanner Link to comment https://www.sau.com.au/forums/topic/43095-o2-sensor/page/9/#findComment-1919267 Share on other sites More sharing options...
wrxhoon Posted February 2, 2006 Share Posted February 2, 2006 Easy with a special socket Duncan but a bit hard if you dont have one . Link to comment https://www.sau.com.au/forums/topic/43095-o2-sensor/page/9/#findComment-1919448 Share on other sites More sharing options...

Cooper Posted February 2, 2006 Share Posted February 2, 2006 So its looking like i will have to buy genuine nissan ones and get a pro to install them for me, bummer i was hoping to save some money.

wrxhoon Posted February 2, 2006 Share Posted February 2, 2006 No duncan and Nissan are rip off merchants about $150 each i think . Copper you should be able to get them off with a spanner, anyway its cheaper to buy the tube socket and then you have it for next time .

Cooper Posted February 2, 2006 Share Posted February 2, 2006 When u say tube socket do u mean a socket like the one for removing spark plug or another type. How hard are they to get to? can u come in from the engine bay or do u have to go from underneath ie take of the exhaust etc?

wrxhoon Posted February 2, 2006 Share Posted February 2, 2006 Its similar to a spark plug socket with a slot on one side going almost all the way down so the cable fits in there, 22 mm . Go to any place where they sell tools even normal auto shops would probably have it and you should be able to get a cheap Chinese one. The rear one is very easy on the gtr ( when you have the tool ), you dont have to remove anything to get to it. The front i think you will have to remove some ducting to get to it .

Cooper Posted February 4, 2006 Share Posted February 4, 2006 I had a look where the o2 sensors are located and they dont seem to be in a very difficult place i dont think it would be too hard with the tool mentioned above and some WD40. I just dont know whether to get aftermarket sensor or OEM ones.

Fly-By Posted February 6, 2006 Share Posted February 6, 2006 Had a read but couldnt find anyone else experiencing the same problem.... My 02 sensor when starting my car basically just sits at 0.3 volts. doesnt cycle like u guys mentioned. After driving around and wen the car heats up the voltage slowly drops down to 0.00 volts! It occasionly slowly comes back up for whatever reason, but definately isnt cycling, pretty much constant reading. Fuel economy isnt the best either 300kms if im lucky. any ideas? obviously not normal.
