I have a manual 2001 Altima with 192000 miles. I am very ignorant when it comes to car mechanics and where or what everything is. With that said, the engine light came up and I got the code to check the EGR valve and passages. I think it was 1401 or 1400. I was able to search how to take out the egr valve and check it. I took some of those vacuum hoses and replace them (some of them were ripped in half). I was very happy about this. I drove the car and the engine light came on again. I was reading that I needed to clean the egr passages too. Here is my question, Is there a picture or drawing that shows what do the passages look like (it looks to me like a bunch of hoses everywhere) and how I can clean them. If there anything specific I need to do. Summer is approaching and I will have time to work on the car. Sorry of my ignorance. thanks in advance for anyone's help.
