Code P1454 Acura Description

The P1454 diagnostic trouble code (DTC) for Acura vehicles indicates a Fuel Tank Pressure Sensor Range/Performance Problem. This code is triggered when the powertrain control module (PCM) detects that the signal from the fuel tank pressure sensor is outside the expected range or is not performing as it should. The fuel tank pressure sensor is responsible for monitoring the pressure inside the fuel tank and providing this information to the PCM to ensure proper fuel vapor management and emission control.
