My 99 Contour SE (V6 2.5l) is having EGR Excessive Flow issues (CEL P402). Based on other posts, it seems like the DPFE sensor is a likely cause. The newer plastic version seems to be preferred to the metal one. However, the dealer told me that the plastic one only fits a 4 cylinder engine and that I would need a metal one for my car.
Looking at my DPFE sensor, it seems like a metal one would be a better fit for the two hoses that connect to the bottom. Is there any benefit to getting a plastic one other than price? And can anyone verify that a plastic DPFE sensor will work with a V6 engine? I appreciate your input. Thanks!
