No problems with EGR valves/system on this model car. Its located under the throttle body. Your valve is electronically controled by the ECM/Computer. Pretty bullet proof setup. What is the actual code number that autozone gave you?? Let me know the code number and will take it from there.

My service engine soon light came on saturday on my 2003 nissan altima 2.5s, took it to the dealer and he stated I need a Catalytic Converter for the light to go off. Last yr Jan I had the same thing happen and there was a recall on the ECM they reset it for free. Any suggestions? I am so tired of getting ripped off being a single woman. The repair price they gave me was $940, my mechanic says he can repair w/new converter total charge of $300

Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with one of the components or sensors it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you need to diagnosed and repaired it. Some problems are minor, but if not addressed it could become major. The list of possible codes number in the hundreds. The code itself doesn't tell exactly what component is defective - it only indicates where to look, or what engine parameter is out of normal range. You or a technician will have to perform further testing to pinpoint cause and the proper repair. Even if you reset the light, if the underlying problem is not addressed it will come back on.
