It is activated by vacuum,but not until the ECM tells it to!! There is a vacuum solenoid that is controlled electronically by the ECM!! It recirculates unburned exhaust gases,it's part of the emissions controls!!does it open under vacum or close..

Reduces combustion temps. I'll get ping on my 1989 if it is not working correctly.
Hi I have 1990 and I recently changed my injectors soon after started getting a code 32 when driving at about 65mph for about 10 miles or so not sure if this problem is related to the injectors but could use some help getting to the bottom of this Thanks!
Update!! I disconnected the vacuum line going to the egr valve and connected a mighty vac to it and it made no difference at idle also it didnt seem to hold any sort of vacuum at all, thoughts anyone?? Im guessing the egr valve went bad.Hi I have 1990 and I recently changed my injectors soon after started getting a code 32 when driving at about 65mph for about 10 miles or so not sure if this problem is related to the injectors but could use some help getting to the bottom of this Thanks!
The 90 uses a positive pressure EGR. Check this link for info on how to test.
