Perhaps you have a blocked cat and this is what the sensor is telling you?

Wouldnt expect it to just all of a sudden block and cause the car not to start at all.

The sensor just unscrews from the cat. Mine still works (AFAIK anyway)

The sensor only makes the warning light come on on the dash, it doesn't send any signal to the ECU.

I changed my fried cat and couldn't get the sensor out so I just cut it and blocked the hole in the new cat with a bolt.

The light comes on and goes out when the car is started.

Your cat may be blocked, or your not starting problem could be totally unrelated...

Try removing the cat and starting the car, if it starts, smash the guts out of your cat, reinstall and buy a new cat ASAP.

Same problem with my car .

My car runs and drives fine tho,but the car wont idle for more than 5mins even after a drive and the owner told me the cat temp is not plugged in thats why its causing it to automatically shutdown or theres more to it than that? & the temp light is always on.

thats the light thats always onpost-112075-0-61525800-1372779439_thumb.jpg

any help would be great.

Yes that's my understanding of the R33 too.

In an R32 the cat over temp light is the check engine light so it does connect to the ecu for that purpose.

Can't understand people hacking wires.

Under the passenger seat you can UNPLUG the cat sensor wiring, no need for butchery.

Fit a grommet in the floor pan hole and it's looking good.

Well mods on the

-Full 3" exhaust

-Fuel pump

-pod filter

-TS boost T

stock everything.

idles fine n drives n sounds fine! But if i start the car let it idle it just won't idle for longer than 5mins its the same even after a drive it automatically turns off the car

But all electronics are on all i have to do is turn the key to the right n it starts again fine.

Try hard wiring the fuel pump using the 'how to', most aftermarket pumps don't like the low power supplied by the factory fuel pump controller. To test it you could run a temporary wire to the battery...

What pump did you install?

well this morning i started up to see how long it will run for

it ran for 12mins n could of kept going so believe it or not it didnt happen today

when i came back from work,it usually runs for a bit n shuts down this time it ran for a while till i got bored like wtf :closedeyes:

i bought the car with the fuel pump already installed.the last owner put it in and he said it holds up to 600hp i believe

Brand- no idea

i'll ask for details coz he said he would fix the shutting down problem anyway.

since he said its cat being unplugged,now i know its not im not happpy :verymad:

Reset the ECU. Quick to do and sometimes solves the problems.

Disconnect battery (negative terminal), Hold foot on brakes, flick lights on and off etc, basically just do whatever you can to drain any residual power.

Wait for 10 mins or so then plug the battery back in and start the car, go for a drive etc.

I'm not sure if the 10 mins of sitting is necessary but just to be sure

    • 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.
