Having problems with your 2006 Chevrolet Tahoe ?
Scanned = p-0449, cleared 2x, replaced sol valve, returned
The usual problem is the vent valve.This is what usually goes bad on these with this code.The vent valve is under the rear spare tire area or by the fill pipe and gets dirt and debris inside and it malfunctions.If you have a scan tool then go into out put test and command the vent valve on and off.You should hear a click.If you don`t hear a click then check for power to the vent valve with a test light.If you have power then replace the valve.Hope this helps.Good luck.
