check engine code PO446
2007 Sierra check engine light came on...took it to Auto zone...code PO446. Did some research and found out this is the solenoid assembly and cannister vent. I just purchased this truck and it is certified, meaning I have 12 month, 12,000 mile bumper to bumper warranty.....so, I'm assuming this fix will be covered under warranty?
