Details of the Ford p0453 OBD Code
The Ford P0453 code indicates a problem with the evaporative emission control system pressure sensor high input.
Ford 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 fuel tank pressure sensor, which is part of the evaporative emissions system.
The sensor measures the pressure inside the fuel tank and sends this information to the ECM for proper fuel vapor control and emission system operation.
