DESCRIPTION
A restricted or blocked evaporative emission (EVAP) vent path is detected by the control module monitoring the fuel tank pressure (FTP) during normal operation. The control module commands the EVAP vent valve OFF, or open, and the EVAP canister purge valve ON, or open. The fuel tank pressure should remain low as vacuum is drawn on the EVAP system. If the vent path is blocked or restricted, the vacuum level will increase and DTC P0446 will set.
DIAGNOSTIC AIDS
An intermittent Condition could be caused by a damaged EVAP vent housing, a temporary blockage at the EVAP vent valve inlet, or a pinched vent hose. A blockage in the vent system will also cause a poor fuel fill problem.

Change the evap vent solenoid canister located near the master cylinder on the right side of the engine or your hoses may be cracked. Good luck!
