Question about 2007 Toyota Corolla
As far as I know there is no code number p4056 in the Toyota code book. It might be:
Error Code: P0456 Fault:
Evaporative Emission (EVAP) System - Small Leak Detected
Malfunction Indicator Lamp (MIL)(K83) active.
Fuel Cap not fully attached.
Evaporative Emission (EVAP) System leaking/faulty.
Evaporative emission (EVAP) pressure sensor.
Check Fuel Cap.
Check Evaporative Emission (EVAP) System.
