hi guys i just installed some test pipes on my car and the service engine soon light came on. I was wondering if thats the 350z version of a check engine light??? what i want to know is if that is the check engine light does that put the car into a timing retard mode to protect the car cause it feels a little slower any help would be great thanks

 

SES is the same thing as a CEL. Go tohttps://my350z.com/forum/intake-exhaust-334/ for some "expert" advice on getting rid of that light and other questions.

 

mine came on after i installed the pipes also. it goes off after a couple of days.

 

so noone knows if it reduces power?

 

^^no power is reduced. its just light bulb. i believe its only on because the o2 sensors are getting used to it

 

sorry guys it sounds stupid but i race honda and if a check engine light comes on it retards the timing and gets slower

 

o. i dont for sure but mine didnt feel any slower

 

two words "non-foulers" problem solved, and whoever said the CEL light will go away after a few days is wrong, the car doesn't "get used" to the pipes.

 

^^mine did

 

what year z do you have?

 

^^ 03 perf.

 

Most 03s do not have an issue with the CEL from test pipes. Its the 04.5 and up that have issues. If you buy a set of non foulers youll be set. You can make your own or you can buy them premade for $20 shipped. Just search around the forums and there are people who sell them. Good luck.

 

The light is on because basically the computer thinks something is wrong with the Cats. The code doesnt affect the way the car runs whatsoever.

 

The light just indicates some OBDII code. It may put the 350Z in "limp mode." May not.

 

I"ve been driving with that light on for about 6 months. It doesnt go away, and it doesnt retard timing, atleast not according to the timeslips.

I put non-foulers on as well after a few weeks to try and get rid of the light. Didnt work, so I may have actually damaged a O2 sensor in the process of installation.

but yeah, its just a light, minor annoyance at the worst, atleast there isnt an audible warning

 

well MY350zIsblack was right after i installed the test pipes and about 3 days later the light just turned off and hasnt come back on thanks for the help....i hate check engine lights

 

^^thank you sir.

 

ive been driving with mine on for over a year. It doesnt hurt anything just get it checked ever so often so you know thats the only code you are throwing. I tried non foulers and no luck here either.

 

thats why yours went out, any 350z over the year 2004.5 will not just go off.

 

so is mine special???? and why do you think that is? not bein a smart a$$. im actually curious
