I have a 2004 F250 6.0, I set my SGII up the other day and it now shows 3 DTC on the gauges. When I try to go and scan it says I have no codes or nothing to show. Is this normal or should I bring it to auto zone and have it read. On the gauge it shows 3DTC. Thanks

 

That's the "problem" that I have with my 04. I'd take it to autozone and have them scan it to see what's up.

 

Certainly worth a try. I suspect "DTC count" is a generic code. If the three codes in the trucks memory are not generic SG won't show them.

Please post back and let us know what you find for codes and make/model of the scanner they used if possible.

 

Will do should be in a couple hours.

 

DTC codes P0403, P0405

They used a accutone I believe

 

Hmm... Would have expected SG to pull those. Do you know what version your ScanGauge is? I don't remember right this minute how to get to it but it's on one of the menus.

Both codes EGR related. It would be worth a try to pull the valve and give it a good cleaning but I think the P0403 is usually a bad EGR valve.
Cleaning works sometimes if the code is for flow but those two are for the "sensor" side of the EGR valve.
Inspect the connector and wiring near the valve before swapping parts.

Here are some SG Codes for EGR (if you don't have them) You may want to see if they will read. Expected values are at the bottom of each set of codes. KO=Key on. LI=low Idle. HI=2,500rpm, OR=Operating range of the sensor you are reading.

Thanks rusty I cleaned it today and still nothing I am going to purchase a new valve tonight would it be best to by from my local ford dealer or elsewhere.

 

You can save some significant bucks shopping online. Dealer can slap one in your hand. I guess it depends on your timeframe and finances.

 

I have a post on here that tells you how to get the best dealer prices. Do a search for Fordparts.com AutoNation.
