Egr flow

[nine23]

There is prolly a thread on this already but I have a cel for the egr flow and I cleaned the ports but it's still there so just wondering if anyone else has had this problem... I read that if you take the manifold off and clean it up that it could help but some people still had cel on.... Let me know cause I think I'm gonna dive into it this weekend

Thank in advance

Re: Eft flow

What's your code? Depending, it may be shared with bad o2 sensor or cat that's triggering it.

It's a p1491 I believe....

like Red said.. it could be related to the o2 sensors.

imo... i would just do the egr delete and check the o2 senors to make sure they're still good

I have to pass emmisions here in Connecticut... Stupid question but would it pass then if i just deleted it? im not really that knowledgeable about emission stuff since im originally from missouri and we dont have to worry about it lol.... sorry for the stupid questions

i honestly dont know if you could still pass without the egr. hopefully another member can chime in on that

I live in Mass, I dont know how different our emissions tests are compared to CT but I HATE IT. I had the same problem as you. So I cleaned all the ports out. The code went away. Then it came back. So I cleaned it out again, went away again. Then it came back again! So I thought it HAD to be that the EGR sensor failed. So I replaced it for $69.xx on RockAuto.com and it the code still hasn't come back.

I'd say you should just replace the EGR valve and call it a day.

insufficient EGR lift...take off the EGR valve, clean it and test it.

 

[nine23]

Yeah that exactly what I was gonna do cause I was trying to avoid having to pay the $125 for the egr so I'll prolly clean it out and if it doesn't go away then I will prolly end up buying a new egr and hopefully that helps....

How do you go about testing the egr? I had it off and cleaned the ports but I didn't know how to test it....
