Hey guys,

I was just cruising down the road at about 50 mph when my Service Engine Soon Light comes on. Nothing changed after the light came on, no slowing in throttle, knocking, noises nothing! I'm just worried something could be close to dying since this light came on. I have not done any upgrades for about a month. Here is a list of performance mods I have installed:

Tanabe Exhaust
Fujitsubo Y-Pipe
Stillen Race Pipes
UR Pulley Set

If I bring the car to the dealer to get it checked will they void my warranty? What should I do, I want my Z to be ok again. ;_;

They can't just go an "void" your warranty. The only way anything will not be under warranty is if the problem has to do with those parts you added onto the car. In which case you either fork out for the repair which it is probably minor, or take it to another dealership and see if they will do it.

Also, it could be a loose gas cap or something too. Check that, and if its fine, just go to the dealer, they plug in their little machine to your car and they will know within minutes what is wrong.

your car is going to blow up...you're screwed...


j/k...just take it to autozone and they can read the code for you...its probably just the race pipes and the code will be an overly rich condition. autozone can clear it or i think resetting your ecu with the pedal procedure or by disconnecting the battery fpr a while clears it.

You can use the diagnostic procedure from the Service manual or the Technosquare website to see what the error code is. I have seen the gas cap issue on both my wife's Maxima and the Z. You can also reset the SES light using the instructions provided.

ironically enough, mine came on last night too! I was just pulling away from a traffic light (it was raining), and bamn, it came on. I was really low on gas at the time, but nothing else about the car has changed. All my mods have been on since forever, so who knows

With the gasp cap, usually after 6 starts/offs of the car the code goes away (got that one once before) - I am on my 8th since it happened, but it is still on. Now the car is sitting with the negative terminal disconnected....will update later. If I could find my palm pilot, I could scan it myself!

I would take it to Autozone. I threw a code about 7k miles after I installed my test pipes and that is what the code pertained to. It went off about 5 days later.

I have the R/T cats, and my light comes on now an then. Performance said it was likely due to the cats. After a day or two it goes out and I may not see it for a couple months or so.

Got my sorted out...was a low thermstate threshold (I forget the code number). Was able to find my Palm and reloaded the OBD2 scanner software to find it out...very handy!

Now if I could jsut figure out how to keep my Palm from eating batteries !

Took it to the dealer, Maroone Nissan. My service advisor is excellent, complimented me on my upgrades and pulled up code for me. He said it was a "catalyst code" and since I had race pipes he said it was that, reset it for me too. How can I keep the ECU from hating my race pipes? I've heard something about an O2 Simulator, a pamplet to install one even came with my Stillen Race Pipes. Jason at Performance Nissan told me O2 Simulators dont come with Stillen Race Pipes so where can I get one?

All anyone needs is a watch with a second hand. If you follow the instructions on ECU diagnostics and resetting your car will tell you what is going on and you can look up the code on the internet. You can also reset the ECU which eliminates the SES light. Quite easy, free and takes a matter of minutes.

yeah but gets confusing sometimes (lots of codes for ODB2) and you need to be in front of a pc
