Thank you wizkid1358! I went to the Tomco website and read the tech tips. The plastic bodied and metal bodied DPFEs both have linear outputs, but they have different slopes. The plastic one produces 1 volt at 0 pressure difference, while the metal one produces less than 0.5 volt for the same difference. When the computer compares the voltage output to it's stored expected value at a given pressure difference, it won't match and an "insufficient EGR flow" code results. So a vehicle that originally had a metal one should get a metal one as a replacement.
