Details of the Dodge p0453 OBD Code

Dodge fault code P0453 relates to a problem with the evaporative emission control system pressure sensor.

Dodge OBD code P0453 indicates a problem with the Evaporative Emission Control System Pressure Sensor High Input.

This code is triggered by the Engine Control Module (ECM) when it detects a high voltage signal from the pressure sensor, which is part of the evaporative emissions system.

The pressure sensor is responsible for monitoring the pressure in the fuel tank and vapor management system.

When the ECM detects a high input signal from the sensor, it sets code P0453 to indicate a potential issue with the evaporative emissions system.
