'02 Maxima - S.E.S light on!

[sotobean23]

Hey Folks,

So I took my car to AutoZone today because the dreaded 'Service Engine Soon' light turned on today! ....Anyways, the error code I got was 'P1320' and here's what the Autozone tech suggested the code meant:

- EGR system fault (exhaus gas recirculation) Explanation - The ECM has detected too little flow on the EGR systems

Probable cause:1. Blocked passage on EGR system2. Failed EGR Value3. EGR solenoid faulty4. Failed EGR pressure sensor where applicable5. Failed EGR position sensor where applicable

Definition:

- Vacuum cut valve bypass valve

Probable cause:1. Failed vacuum cut valve bypass valve2. Blocked line.

Any pointers/suggestions as to what I can do? I am far from mechanical but definitely willing and wanting to learn. Don't really wanna take it to a mechanic but if I have to I will. Any advice would be greatly appreciated!

Thanks!

I show P1320 as being an Ignition Signal problem. EGR should be P0400 and P0403. So the code and definition given to you by Autozone don't match up. Here's our list of codes and their definitions: zerothread?id=126537

Was that the only code that showed? Is the car running as well as normal? Any rough idle or other noticable problems?

Now that you mention it, I do recall seeing the P0403 code as well. So there was 2 codes...P1320 and P0403. As for the car, it's running pretty smooth as usual but at times I do notice a weird noise as I'm turning on the car the first time. It makes a noise as if I was turning the ignition key too much. It doesn't do that all the time, but I do notice it. Everything else is in pretty good shape.
