Has anyone else had any problems with their EGR valves? I have gone through several and think that I am losing the one currently in the car. Also if anyone has any reasons as to why they don't last.

 

Where is the egr? Is it just above the Y pipe or is it under the uim? Whats the benefit of removing it?

 

the service manual shows it just above the turbos and beside the plenum. the mazda service guys say that because of the extreme heat that is why they blow. I just do not know if that is the case or not.

 

Yea thats it. The other one is the acv.

 

If you remove the EGR valve capping the ends the check engine light won't be on, will it?

 

i think my egr went and the check engine light came on

 

Yeah dump that egr. Either get a block off plate or just block the vacumm signal going to it somehow. It will pass smog with it disconected as long as you fool the ecu with a relay to make it think it's working so the check engine light wont come on. Its easy to make it "look" like its still conected. As far as hooking up a relay to it, the two wires going to the switch button on the egr get switched together when the egr opens. So all you have to do is wire a relay off of the egr solenoid harness under the upper intake manifold to switch the two wires going to the button on the egr together when theres power going threw the harness. I might not be explaining this very well. Do a search, thats how I found out about it. It does work, I'm sure of that.

 

I think if you have aftermarket ECU e.g. Power FC. You do not have to worry about the engine check light.
It was pulled anyway from the ECU plug.
And removing, then capping the EGR hole should take care of the problem.
