P1452 2006 Toyota Prius Code - Fuel Tank Pressure Sensor Low 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 P1452 2006 Toyota Prius Description
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 accurateThe 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.
