ENGINE - 2AZ-FXE ENGINE
D A control system that functions as follows is used: When the
engine is stopped while the vehicle is in motion or stopped, the
fuel vapor-containment valve keeps the fuel tank sealed to prevent
the fuel vapor from being discharged. Only when the engine is
operating, the fuel vapor-containment valve operates, allowing
the canister to absorb the fuel vapor, which is subsequently
consumed by the engine.
D A refueling control system that functions as follows is used: When
the internal pressure of the fuel tank is high because it is sealed,
this system lowers the internal pressure of the fuel tank before
opening the fuel filler door and refueling the tank.
D Approximately five hours after the power switch has been turned
OFF, the THS ECU operates the canister pump module to detect
any evaporative emission leakage occurring between the fuel tank
and the canister through changes in the fuel tank pressure.
Prohibits fuel delivery, ignition, and starting the THS II if an attempt
is made to start the THS II with an invalid key.
When the THS ECU detects a malfunction, the THS ECU diagnoses
and memorizes the failed section.
When the THS ECU detects a malfunction, the THS ECU stops or
controls the engine according to the data already stored in the
memory.
