hey everyone. i need some help. So i got myself a jspec motor. hella clean. when i was swapping the wire harness over (they cut the one from the jspec motor) i noticed in the rats nest that there was no EGR Valve sensor (yellow plug). then i looked on the intake manifold and there was no EGR valve. So, being that my USDM wire harness has the yellow plug but there is no EGR valve, will i be getting a "Check Engine" light?? Also, I live in a town that does not need emissions. if anyone can guide me (with pictures; before and after) as to what stuff i can take off the rats nest that'd be great too. thanks for your time.

Are you using the stock ECU?

 

yeah.

 

If you have a Cali based ECU, then yes you will get the EGR CEL. However, I don't believe that will cause any performance problems; just an annoying dash light.

If you don't have a Cali based ECU, then you just need a resistor for the EGR solenoid or you can just connect it and not connect any vacuum lines to it.

 

how can i tell if i have a cali based ECU??

 

Easiest way is to plug everything up without the EGR and see if you get ECU code:

16 - EGR valve (California only)

 

I have a cali car.

my egr was giving me cel light on the dash, so I unhooked the vacuum line and plugged the holes.


I only sometimes get the light on.

I did mention i plugged the holes.. Is this ok? I copied the read me from rob rinnete or watever his name is website =)

 

so if the Check Engine light does come on, will my car boost right (10-8-10)?? or will i be in limp mode?? if i can boost right, i will just put the resistor on so that the Check Engine light will possibly be off.

 

Not every CEL code puts the car into limp mode. I don't believe the EGR code will do that.
