If I were you I would return the EGR valve, I too replaced EGR valve after getting this code and it came right back after about 150 miles...Troubleshoot first with the EGRC solenoid,,replacing this should hopefully resolve this issue.

 

That's what I probably will do, but I am going to hold on to my egr valve either way. Next, time I drive by the nissan stealership I will find out how much they are going to dig in my pockets for an EGRC solenoid bet I am not getting code 1005.

 

Replace your coil packs. What your describing is a signature of failed coil packs. The CEL flashes when a misfire is detected electronically. You have a faulty coil pack, it's a common failure. Unfortunately your ECU can't figure out which one it is so your not getting a code for it. If the secondary side of the coil has gone out, the primary side, which is what the ECU can measure might be still working. If thats the case then the ECU cannot see the error.

Both crank position sensors are used to detect misfires that will flash the CEL. They are serious enough to disturb the engine's smooth rotation enough for them to detect it, therefore bad for the engine - thats why the CEL flashes when your under a load. Gas pedal down around 1/3 sets it flashing, but if your gentle the car will drive without the light flashing.

If thats whats happening, then it's your coils.

 

ive had this code for over a year, and there hasnt been a problem besides the damn code, although my tb probably looks like the inside of a large intestine right now so im gonna clean it after winter.

 

ok here's a brain teaser . . . .
All my EGR related components have been changed for brand new OEM parts. All coils were changed in July. Yet the EGR 0302 code lights up. It goes away automatically after several computer cycles but comes back on. So here goes . . . . the SES light only comes on when i am going at a steady speed of 50+ mph and then suddenly let go of the gas pedal for a panic/abrupt stop.
Any ideas on this one?

 

Sounds like mine but my code will come on if I use the AC fan or stop in go driving.

 

wow this THREAD is getting really interesting. I have same Problem and now waiting what erbentraut will find.? please help this poor guy finding how to find which coil pack is bad as it will help alot of other ORGERS like me who are in trouble for this code...

 

So just as an FYI - the code went away for a few weeks then came back. The car ran great though - the coilpacks were definately the culprit causing the misfire. I could care less about the stupid code ... I never did get it resolved ... I got so tired of it, it gave me a good excuse to buy a new 350z .... do I did.
