hey everyone,,

my car was misfiring a bit recently,,,, so first thing i did today was run the ecu diagnostic,,

ran the engine for a few mins,, then ran the diagnostic,, and came up with error 17 & 46,,

thought it might have something to do with the car not being warm enough,, so i wamed up the car,,, but it still showed the same error,,,, while i was there, i ran the 02 sensor diagnostic,, that came out fine,,

wierd thing is,, last week i was only getting error 55,, i.e all good,, and now am getting 17 & 46,, and i can't find out what these mean,,,

car seems to be running fine,, i.e boosting,,,, had the plugs checked out few weeks back,, they r fine,, injectors are clean,,

anyone got any idea's?

, none,, except exhaust,,,

everything else is standard,,,

i also checked all the coils,, they all had about the same resistance,, can't remember how much it was,, but they were all the same,, so i figured it wouldn't be the coils,,,

i sprayed wd40 in all the connectors i could get to,, but still the error keeps coming up,,

its wierd,, coz the car seems to be running fine,, except for the misfire here and there,,,, but its the error codes thats got me baffled,,

How do you get into diagnostic mode to being up the error codes on the 34?

same way you do the other skyline,,, find the diagnostic plug,,,,

its under the driver's side dash... have a look underneath,, the dash,, alsmost inline with the accelerator pedal,,, (i think),,, there should be a small black cover,, take that out,, and on it will be attached a grey plug,, i used the paper clip method,, u get to diagnostic mode,, i'll try to take pics to show where the plug is,, but you should find it fairly easily,,

type in "paper clip ecu" in the search path, and i'm sure u'll come up with something,, if u get code 55, than all is fine with the ecu diagnostic

either way,, i still have the errors,, its so annoying,,, car is running perfectly,,,

Hi Afro

ylwgtr2 wasn't correct with his comment "bnr34 code 46 is an abs code,and theres no 17 listed."

If you have a R34 with a RB25DET (he might be using r33 data) code 17 means -

ABS-TCS control unit circuit

- Throttle control unit detects malfunction in the system (open throttle sensor harness etc.)

- TCS/ABS control unit detects malfunction

A 46 means -

Throttle Motor sensor signal circuit

- Throttle motor sensor input voltage is approx. 4.8V or greater (open circuit) or less than 0.3V (short circuit) for predetermined time.

So I'd say you have a throttle or electrical problem...

Hope that helps.

hmmm i would have to disagree with you on that one ian,and agree at the same time.....BNR34(GTR) code 46 Is definately an ABS code.....I understand that he has a ER34(GT-T) thats why i stated BNR and not ER....I posted the info as a guide as ER and BNR "may" be the same....Although i shouldve posted that part!!72 is the BNR 34 TPS code

Yep, I understood he had a ER34(GT-T) and for that car the codes are as I mentioned (it's the same car as I have:-). (44 on his car would be a coms problem with the ABS..)

      RB20DE NEO smallbox clutch.

      By Duncan · Posted

      yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      RB20DE NEO smallbox clutch.

      By MBS206 · Posted

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.

      That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.
