Does this value tell you anything about the condition of your EGR valve?

I inputted it on the Scangauge xgauge, and get a readout usually within the operating range of 0-14...but a few times it spiked up to somewhere in the 80s.

 

I've been wondering this too... I didn't see that code on their site when I programmed my gauge a while back, but I've been seeing people asking about it on here.

 

Mine runs consistently from 0 to 5 but I have also seen it go to 80 one time.

 

Did not get much response on this, so I will try again.

Does the EVM readout tell ANYTHING about the condition/function of the EGR valve?

 

Wish I could help on your post. I have a delete kit. My ScanGaugeII results wouldn't help much. Most of the guys are probably watching football right now. Give it time, someone will come along with an answer.

 

there is also a "EGR Desired" and when I am showing both this and the "Measured", it appears that it can be telling you how well the valve is actually meeting the setting command, which might inform if the valve is lagging or failing to open or close or whatever.

Having only my own to compare I don't know what normal should look like. It always eventually measures whatever is desired, but it's not instant and there are times when measured will spike way off what desired is. Makes me think, just from watching it, that it might be getting 'sloppy', being pushed around by the flows rather than holding what it's told to do.

Just an impression, I don't know.

 

My desire and measured always move together and stay the same. I can't help any more than this.

 

Sorry for chiming in but do any of you no what the EVD and the ETP on the scangauge shoud be reading at idle? I can not got the EVM to read on truck for some reason. But I am trying to pin point a problem with my truck and this thread caught my attention. My scangauge is showing my EVD to be 11 @Idle and my ETP is -4093 @ldle and it only goes up to -4094 when I rev up the rpms? Sorry for the hijack but i am going crazy trying to figure this thing out!

 

No idea, and so off topic you may just wanna start your own thread.

 

How could it be off topic? they are the other two EGR functions measured by the scangauge. I thought that was what you where asking to Sorry about that.

 

I'm not sure what all these mean, you guys are seeing the readings. I got these OP values from a Tech. I just hope I separated them correctly. At the bottm you will see how I got them.

Hopefully someone with a little more info can chime in here. I see I might have operating values in 2 spots for 2 different Gauges. I Would like to be set straight on this.

right now I'm running with the EGR connector disconnected. My '05 has a very early flash and this does not cause a CEL or fan problems. EVD still varies with conditions, but EVM always reads 100.
