I had my car inspected and received codes P0440, P0441, P0446. I understand this emissions, but what exactly needs to be fixed and how should I go about this to not get overcharged or ripped off and make sure it gets done right the first time.
Where is Evap Emission Control System Purge Flow fault
Error code P0446 is an Evaporative Control System vent control
malfunction. DTCs P0441 and P0446 are recorded by the ECM when
evaporative emissions leak from the certain components, or when there
is a malfunction in either the VSV for EVAP, the VSV for
pressure switching valve, or in the vapor pressure sensor itself.
You need to replace the check valve, Genuine Toyota Check Valve 77390-52010
