my car toyota corolla 2000 VE
engine light is on - PO446
Brought it to check in auto repair, they said no leak in this assembling(EVAP system).

Answer 1

HI there,

If there isn't a leak in the evap system and you have this code, then it's likely the fuel pressure sensor causing the code. If it's not reading properly it will throw an evap code.
