What does the p0440 code on a Toyota mean?
The P0440 code means that the control module has detected a leak in the Evaporative Emission (EVAP). Loose fuel tank filler cap is the most common cause that triggers the P0440 code. The cost to diagnose the P0440 TOYOTA code is 1.0 hour of labor.
Where is the p0446 code on a Toyota Camry?
The P0446 codes triggered when an improper voltage signal is sent to Engine Control Module (ECM) through EVAP canister vent control valve. The Evaporative System ( EVAP) canister vent control valve is located on the EVAP canister and is used to seal the canister vent.
What causes the EVAP purge solenoid to be off?
The ECM commands the EVAP Purge Solenoid OFF once the system has reached a predetermined level of vacuum. This test verifies if a vacuum can be achieved in the EVAP system. Failure to develop a vacuum may be caused by a large leak or a restriction.
