Hi all

After a long discussion with my auto leccy, we have seen that the ford EF/EL sensors shouldn't be used on skylines. Ever since installing one of these on my car, I have had problems with it. On the scan tool it showed us that the o2 sensor was dropping to 0v, then back up to around .8-.9v at idle. The actual graph showed the o2 sensor was sending all f**ked up signals to the ECU. I dont know if any of you other guys have had the same problems (mostly idle prodlems) that are using the Ford o2 sensor..

has anyone had the same experiences? I may be opening a can of worms here but I'm interested to know.

Thanks guys

zactly.. had the same problem when I put one in the 32.. doesn't work as it should... see my warning here too :)http://www.skylinesaustralia.com/forums/in...ic=43095&st=400

10 mins on the dyno and monitoring the voltage correctly via a datalogger showed this was the case.

It 'kinda' works.. but not properly.

You are best off with an original item, even if it does cost that much more.

My Bro-in-law had a generic aftermarket O2 sensor in his 32 and had an intermittent idle problem where the revs would drop and then pickup (if it didn't stall). I spent ages trying to identify the problem and he even purchased another new generic O2 sensor and still had the same problem. I eventually found it to be the source of problem when I could rectify the low idle revs by disconnecting the sensor. Plug it back in and the revs dropped.

Replaced it with a factory item and hasn't missed a beat since.

I have fitted a el o2 sensor into mine and had no issues. ('93r33) On the dyno, it runs a tad leaner, but occilates between 14.6 and 15 AFR on idle, but looks to be OK. The stochiometric point is probably a little leaner than the regular item.

Your choice, should you choose to use it.

I have an EL falcon Sensor in my series 2 gtst and its been great. I got better fuel mileage too. Havent had any idle problems.

Strange some people are fine and some have problems

Maybe its just an R32 problem? then again, its probably a different sensor :D I think that is mentioned in the big o2 thread.

Yes, you are right. The R32 use a Titania oxygen sensor, this is different to the Ziconia sensors used on other Skylines, and is not interchangeable. No wonder people are having problems on R32's if you're using the wrong type of sensor. :kiss:

Does any one know if the R33 GTST sensors (NGK or other brand replacement) work on a GTR ive been trying to find a cheaper option than going to Nissan and no other retailers supply O2 Sensor for the GTR.

Check out the NGK (Aus) website, they should have an NTK replacement for the GTR.

      r34's love to squeal

      By Nizzy_R34 · Posted

      just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.

      My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.

      To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?

      So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
