How To Check For Error Codes

Hi Guys, I am having a little issue with my idle still. I have replaced my O2 sensor, cleaned and resoldered my AFM, Cleaned my ACC Valve and reset my ECU.

The problem is that it idles at 1500-2000rpm for about 5secs and then drops down to normal!

Resetting the ECU has fixed the problem before but it came back the other day after a big drive (400KM).

I am happy to reset it again, but I am guessing it will continue to occur and due to it fixing itself after a reset it should be electrical and I think it would be worth checking the ECU for error codes and might be able to narrow it down.

I have had a look but I have not found anything conclusive.

Can someone instruct me how to check for codes (is it a light that flashes a certain number of times and that number corresponds with a particular fault?) and could someone post up a list of the codes and their meanings? Any other help would be great!!

I have also read about a consult cable that connects to your notebook... This could be good, would this be a better option?

If I am able to get all the info it could be an idea to add it to the FAQ sticky.

Thanks guys!!

Todd

There will be a tutorial somewhere, otherwise any number of previous threads on how to recall the error codes from the ECU. Note however that any errors are retained for 50 "start cycles", so an error showing up is not necessarily related to your immediate problem.

To your immediate problem - how often does it do this "fast idle" cycle thing? Frankly, still sounds like a problem with the AAC valve - it needs to be stripped right down and thoroughly de-carboned.

The problem happens ALL the time. Not just when cold or first starting.

I can drive solid for an hour and stop at the lights and it will idle at 1500-2000rpm.

This is most anoying when in traffic and you are bumping along at low revs but every time you put your foot on the clutch it jumps up.

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.

      Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
