Well mine is sort of like that but my egr position sensor is right before the EGR valve. From the intake manifold the hose goes to the EGR position sensor then comes out from that into the EGR valve. I think ive figured it out though. I think its just b/c my damn truck wont get to normal temp so it stays in closed loop. When its doing the KOER test and the temp isnt at normal would it not use the EGR valve and throw that code.
