EGR valve help

[D-money]

95 c280
so my check engine light came on, pulled the codes and they were p400, p411, p170. i highly suspect that all these are related and is caused by one problem. Doing some research i found out that p400 is probably because my EGR tube is clogged and needs to be cleaned. im hoping that if i clean it out the cel will go out. the problem is i need your guy's help on how to go about on cleaning in. do i have to remove it, or can it be cleaned unremoved?? if i have to removing it, how? how is it removed?

any help is appreciated,

My CEL just turned on out of the blue. Car runs as normal and theres no issues. Im suspecting that its an O2 sensor or my EGR tube needs cleaning. what how and where?

[Nelson Lago]

well if its an o2 sensor i dont think theirs anything you can do but buy a new one and their not cheep dont know the price but i think its a around 100$ as far as egr if its stuck due to carbon build up theirs a samll possibalty you can free it up

FWIW, I have seen posts from people who after they had it disconnected had success using an old speedometer cable to "snake it" out and then used throttle bottle spray to jet out the loose stuff

ya somthing like that but i dont have the same year as you so i really dont know where yous looks like to see where to clean it but i would say maby a coat hanger so scrape some off adn like xvvvz (werd name) and spray some brake clean and if you can maby the last some lube (wd-40 or sea foam)
