joe, the delta pressure feedback exhaust gas recirculation (DPFEGR) sensor is easy to identify. just located the EGR tube, and find the 2 usually short hoses around 3-4" long that branch off of it and are connected to a small black plastic or aluminum rectangle shaped sensor with a connector hooked to it with 3 wires if i remember correctly. all cars have a different one. there is a recall.......02M01 is the number which extends the warranty coverage on most late model ford vehicles. check with your local dealer to find out if your in the coverage.
