2002 egr valve problems

Something is going on with the egr valve in my mazda 2002 tribute.
Something seems to be creating pressure strong enough to blow a hole in the valve. Has happened twice in last 2 months. Problem started after taking care to a precision tune and they replaced the part as part of a tune up service.
They are planning on doing a diagnostic on the cat converter to see if there is a blockage causing a pressure build up.

    My garage is telling me that they don't think it is the catalytic converter, they have replaced #5 & #6 coils and replaced rear converter, anything else could be causing these problems?

That would be exactly what I would look for... When the catalytic honeycombs become blocked, it causes a build-up of exhaust pressure... and this restriction in the exhaust will also have a very definite effect on engine performance: The typical symptoms are an engine that initially seems to running okay, but slowly loses power.. in severe cases it will lose power to the point the engine stalls and will not restart until the pressure build up bleeds off.

Good luck with the problem --- it sounds like you are on the right track. And don't forget to rate my advice: your approval is my "paycheck"!

Thanks!

The front cat is bad for cracking apart and falling into the elbow in the pipe below it. Over time the honeycomb erodes from the extremely hot exhaust blowing, not through the comb, but against the side of the broken off piece down in the elbow. Over time the tiny pieces that blow off it clog up the third cat just behind the flex part of the exhaust. You must replace the front cat, or cut it open and clean it out and re weld it shut, and also replace the third cat...or but clean it out too. Bypassing the two cats don't cost a thing and the egr is 50 bucks. It will run like a top. If you only replace the front cat and the egr, the car will not be able to go over 50mph and your new egr will blow.

Hi I seem to be having the exact same problem that you did. I got a new EGR valve and about a month later it happened again. I was wondering if you ever resolved this problem because we cannot seem to fix the problem. Hope to hear back soon!

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.

You probably will have to take your Mazda to a mechanic and have everything replaced that you ruined by power washing the engine.

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 problem, took it to Autozone for diagnose and theys say it can be either the EGR valve or de EGR pressure sensor, how can I check what problem it has? thanks.


The valves rarely fail, what usually happens is the passage that delivers the exhaust gas into the intake manifold gets plugged. It is possible you have a problem with the sensor but the code should tell the difference between the two. What is the trouble code?

I can't find the location of the DPFE (EGR pressure sensor). I've already replaced the solenoid, but can't find this sensor anywhere.


Usually mounted on driver side,on a bracket over exhaust manifold or on a bracket on intake manifold. One of the 2 hoses that attach to it goes directly to egr valve. If you still cant locate it follow hose from egr valve it ends at sensor.
