You can download a schematic of the car etc on the manuals thread (wherever it is on the latest version of the forum). Try a forum search for "manuals".Hello everyone,
Working on my 2000 Insight MT 95K and still having some jerking problems. So I am looking at the EGR valve to possibly fix the problem. The EGR has been cleaned before in the life of this car but not sure when. So I attempting to clean the EGR by spraying electronic terminal cleaner into the top portion but I am not sure how to cycle the EGR from open to closed. I have five terminals to put the positive and negative leads too but from reading the threads I didn't read about where to put your positive and negative leads. I can just use the regular 12v car battery for this correct?
These are the 5 terminals/connections

So where do I attach gator clips too?
IIRC The valve starts to open a little over 2.3 V which is controlled by the engine ECU.
12 Vdc is way too much voltage for the valve.
My MT engine has to be above 154° F before lean burn can engage and it's best for the engine to be fully warmed up for testing.
Try disconnecting the EGR connector and see if that gets rid of the herky jerky. The valve should be closed while in lean burn.
My Accord EGR valve cost $5 from my favorite junk yard. Over the years I've found that junk cars will sometimes have brand new-last-resort parts to fix the car before it was junked. My EGR valve was new and made by Seimens.
I would guess if it looks like an Insight EGR valve it should work.
