I recently took all the emmisions stuff off my truck but left the EGR valve and I did a KOER test and got the following codes:

33-EGR Valve Position sensor o Pressure Feedback EGR sensor indicates EGR valve is not opening. or EGR Valve Position sensor or pressure Feedback EGR sensor indicates EGR Valve not seated (closed) properly.

44- Problems in Thermactor Air Control System

If anyone has any idea's please share.

 

no advice anyone?

 

The coffee can you took out will help that, but you'll have to see if that's the only problem after it's back together and running.
