Code P0453 Infiniti Description

The P0453 code for Infiniti vehicles indicates a high input signal from the EVAP (Evaporative Emission Control) system pressure sensor. The EVAP system is responsible for capturing and storing fuel vapors to prevent them from escaping into the atmosphere. The pressure sensor monitors the pressure levels within the system to ensure it is functioning correctly. A high input signal from the sensor suggests that there is an issue with the pressure levels in the EVAP system, which can lead to increased emissions and potential environmental harm.
