P1453 2009 Toyota Prius Code - Fuel Tank Pressure Sensor High Input

Quick Answer

While the engine is running, if a predetermined condition (closed-loop, etc.) is met, the purge VSV is opened by the Engine Control Module (ECM) and stored fuel vapors in the canister are purged to the intake manifold. Common causes include Faulty Fuel Tank Pressure (FTP), Fuel Tank Pressure harness is open or shorted, Fuel Tank Pressure circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1453 2009 Toyota Prius Description

While the engine is running, if a predetermined condition (closed-loop, etc.) is met, the purge VSV is opened by the Engine Control Module (ECM) and stored fuel vapors in the canister are purged to the intake manifold. The ECM changes the duty cycle ratio of the purge VSV to control purge flow volume. The purge flow volume is also determined by the intake manifold pressure. Atmospheric pressure is allowed into the canister through the vent valve to ensure that the purge flow is maintained when the negative pressure (vacuum) is applied to the canister.
Key-off monitor
This monitor checks for Evaporative Emission (EVAP) system leaks and canister pump module malfunctions. The monitor starts 5 hours after the power switch is turned OFF. More than 5 hours are required to allow the fuel to cool down to stabilize the Fuel Tank Pressure (FTP), thus making the EVAP system monitor more accurate. The leak detection pump creates negative pressure (vacuum) in the EVAP system and the pressure is measured. Finally, the ECM monitors for leaks from the EVAP system and malfunctions in both the canister pump module and purge VSV, based on the EVAP pressure.
