Code P0453 2002 Nissan Sentra Description

The P0453 OBD-II trouble code refers to the EVAP (Evaporative Emission Control) System Pressure Sensor High Input. This code indicates that the signal from the EVAP pressure sensor is higher than the expected range under normal operating conditions. The EVAP system is responsible for capturing and storing fuel vapor emissions from the fuel tank to prevent them from escaping into the atmosphere. The pressure sensor measures the pressure within the EVAP system to ensure it is functioning correctly.
