2007 GMC Diagnostic?

[CATNHAT]

Anyone have a GMC diagnostic tool for determining codes? My check engine light is on in My GMC Yukon, 2007, dealership wants $90/hr to "diagnose" the problem.

Thanks

Thanks Dr. Buick aka Jim for all the help today! Scanned my truck, obtained an accurate diagnsosis, then did the research on the interweb and printed off an 8 page description with detailed parts, and step by step instructions!

Stopped by EVS on the way home, picked up the parts for $30, went home and fixed the truck in about 1 hour!

Probably saved me about $150 at least!

Thanks again--I really appreciate it!

Dealers overcharge. That's why I just work for one, haha.

so what was the issue?

Engine light came on. Code was for a malfunctioning EVAP CVS filter. TSB recomends replacing the conduit, install new CVS (canister vent solenoid) Valve and filter.

Apparently the valve and filter are one piece. I had to lower the spare tire to get access to the filter. 2 hoses and 1 electrical connection were all that needed to be disconnected and then reconnected. Went pretty smoothly accept one of the hoses is a rigid, almost pvc grade hose that broke. I had to heat the end with a hairdryer to get the hose pliable and reconnected it.

Since I do not have a scanner, I was not sure how I was going to reset the computer to eliminate the code. I disconnected the battery for 2 mins and VOILA! All fixed!

This was done on my 2007 GMC Yukon Denali XL, BTW.

That formed hose on the vent valve can simply be cut with a hose cutter, and then you install a piece of 5/8" heater hose between your new valve and existing hose with a couple of hose clamps.
What code did you have? P0446 p0449 or p0455?

Not sure, I did not see the scanner.

IIRC, Jim said it was the P0446 Vent valve.
