Continue to get a EGR low flow code on the car. I have removed the EGR to making sure it is clean and the plunger moves freely. Checked for clogging and debiris in ports and all appears OK. Is there a way to test the EGR valve itself by connecting it to 12 volts on a bench? Which wires at the plug supply currnet to the EGR and what activates them? Appreciate any help to test before I go buy a new EGR.
