Had a look at my egr valve and noticed it only has 2 wires running to it.Does that mean it's a simple solenoid valve is on or off?I put my scanner on it and watched the commanded egr and egr error.At wot it commanded 4.7% with little egr error which seems to imply it's working fine.The question I have is,Does the egr valve send a position single back to the ecu in order to achieve the correct commanded egr percentage.Some other egr valves I have worked on before had a reference position by means of a pintle position 5v referenc that have more than 2 wires.
