check engine light

[drewzx3]

I just got my car back running from changing motors and now the check engine light is on. The code is 332 insufficent egr flow detected. What all could be causing this?

broken vac line to the egr valve. mine throws that code like everytime I drive it. Its becaue my vac lines broke and i have then held together with a piece of rubber hose. Not sure if it can get cloged up inside or not

That sounds right. when i changed motors i changed to a trick flow intake and the egr vacume line was to short to reach so i had to get another one that was laying around the shop and it doesnt fit tight.

yeah when mine snaped it kinda smashed the ends and has gave me issues ever sense

If you notice detonation, fix it ASAP.

Good luck.

I havent noticed any but I have only drove it a few miles.

if the hose checks out ok, hows the gasket? also maybe the egr tube has a pinhole or crack. just some other areas to look at.

Just delete it and be worried no more, unless you have emmisions.

thats really the best fix, i ditched mine and haven't looked back.

I wouldnt personally dlete it unless I could turn off the EGR function in the computer.
That is just me.

I replaced the hose and the gasket is new.

You can apply 5-6" hg of vac to the nipple on the EGR valve and watch the diaphram travel. A bad diaphram can cause it to not move much. Also one can remove the valve and clean it out (they coke up). This can also reduce the flow (the debris in there causes the inert gasses to bottleneck).

It takes 5 mins or so to remove the EGR valve (two bolts or nuts, the feed pipe [soak it in PB first] and the vac line. I think that is it).

Good luck.

Can someone post a pic of the vacume line that runs off of the egr valve and the others so I will know I have all of them in the right place.

 

[MysteryMachine]

Sure man i'll run out and try to get some now.Sorry I haven't got them to ya yet just got on the computer

I think I had a vacume line in the wrong place. I swapped two around and it has not came on since. thanks
