Where is DPFE sensor 2002 mazda tribute V-6


Between the engine and firewall. there is a metal tube that connects to the exhaust manifold and the EGR valve. EGR is close to the throttle body. On this tube you will see two other tubes coming off it, with rubber hoses attached. On the other end of the rubber hoses is the DPFE sensor. It has an electrical plug, wit two wires.

Multiple engine codes 2002 tribute. p0171, p0174, p0300, p1401


I doubt it.
Codes 171 and 174 are for lean fuel mixtures, 300 is for random missfires which could be fuel or ignition related, and 1401 is for a problem with the EGR valve system. Now the EGR could cause the other codes if the valve is open or leaking when it should be closed.
The EGR valve and sensor would need to be tested first.

Egr valve keeps failing may have clogged catalytic onverter


That would be my diagnosis as well. Have someone follow you while you're driving it. Many times a vehicle with a failing cat. converter will smell like sulfer or rotten eggs to someone driving behind them.

Code 402 0n 2001 mazda tribute


A code P0402 most likely means one or more things has happened. The DPFE (differential pressure) sensor is faulty and needs to be replaced, there is a blockage in the EGR (most likely carbon buildup) or the EGR valve may not be opening due to a lack of vaccuum.
