Yes, it is the EVAP Vent Valve Solenoid Assembly. Is mounted on the frame just above the rear axle and in front of the rear part of the gas tank.

ok, there are two different bulletins for vent sol. one is for the truck models, which you do move the vent sol. to another location. on the suburban, they mount in the same location, with a new designed braket. here is the info that applies to your vehicle.
Some customers whose vehicles are operated in dusty type environments, such as farming or mining off-road type applications, may comment about the illumination of the instrument panel SES light, with a DTC of P0446 (Restricted/Blocked EVAP Vent Path) being set.
Dirt and dust intrusion into the EVAP canister vent solenoid, resulting in restricted air flow, may cause this condition.
After following the Service Manual diagnostic P0446 and determining that the EVAP canister vent valve is the cause of the SES light, replace the existing EVAP canister vent solenoid and bracket. This new vent solenoid has an enhanced filtering capability and a filter element that can be easily removed and cleaned. To ensure correct installation, follow the procedure below.
Tighten the bracket mounting bolt to 12 N·m (106 lb in).
Bracket, EVAP Emission Canister Purge
Valve, EVAP Emission Canister Control
If I mont it to the same location, the line that goes to the canister will be to short. It would need to double the length. Did they give the wrong part?.
Ok, then for sure you got the wrong part. here is the correct part number
The only thing that gets me is everything that I have read says that it has to be reloacatedand if is for pickups. Nothing really points to suburbans, also i have seen the same issue with avalanche.
Yes please if you would.
