Took it to the nissan dealer and the told me that it was the EGR Valve and EGR Valve position sensor. They want $800 to repair this problem. The check engine light sometimes stays on and sometimes it turns off. Is there a way to clean the EGR Valve? What parts are involved with the EGR Valve? THANK YOU FOR YOUR HELP.
Hello,
But if something triggers the check engine light to come on, shouldn't it stay on until the problem is fixed or the check engine light reset? The cars seems to be running perfectly, except for the check engine light turning on and off. Can it be an electrical problem?
