Do you have access to someone with a Tech 2 that can command the EGR pintle on and off. Then watch the actual position of the pintle while commanding it on/off. If you have 110% verified that there are no leaks caused by cracks in the stovepipe of EGR piping, check to make sure that all gaskets at pipe connections are secure, as well as the point of entry into the intake plenum/TB.

After that is verified NOT to be the culprit, it can only be electrical and would most likely be a ground/short somewhere in the harness. You may even be tipped off to this electrical issue when trying to command the EGR on/off. Have you checked the fuses/relays for the EGR system. I guarantee that the troubleshooting list is gonna ask you to check with a test light or DMM, the EGR feeds to any fuse/relay in the fuse block!

Iím at work, so I canít pull the code and ití* troubleshooting list from SI, so I will have to do it tonight when Iím at the shop.

I pulled the TB and EGR tube again, just to make sure there are no cracks. I aslo cleaned the EGR tube port with a whole can of TB cleaner. I also cleaned the connection harness to the EGR. I still get the EGR code.

I tried to trace the wiring to check for shorts/grounds, but did not get very far. The wiring dissapears into the main harness coming off the top of the engine.

I agree that this must be a wiring issue, but don't know how to find the problem. Any suggestions?
