The P0453 trouble code pertains to the Evaporative Emission Control System Pressure Sensor High Input. It indicates that the pressure sensor in the evaporative emission control system is detecting a high input, suggesting a higher than expected pressure level within the system.
Evaporative Emission Control System Pressure Sensor High Input
Code symptoms P0453.
1. Illuminated “Check Engine” or “Service Engine Soon” light on the dashboard.
2. Fuel odor around the vehicle.
3. Rough idling or stalling.
4. Difficulty starting the engine.
This code is common in brands such as:: Chevrolet, Renault, Ford, Toyota, Nissan, Mercedes Benz, Honda.
Causes of the code P0453.
1. Faulty evaporative emission control system pressure sensor.
2. Wiring or connector issues in the pressure sensor circuit.
3. Corrosion or damage to the pressure sensor.
4. Blockage in the evaporative emission control system hoses or lines.
5. Fuel tank over-pressurization due to a malfunctioning vent valve.
Code Solutions P0453.
1. Inspect the evaporative emission control system pressure sensor for proper operation and replace if defective.
2. Check the wiring and connectors in the pressure sensor circuit for damage or corrosion and repair as necessary.
3. Ensure proper electrical connections to the pressure sensor and address any loose or damaged connections.
4. Examine the evaporative emission control system hoses and lines for blockages or leaks and repair or replace as needed.
5. Verify the functionality of the fuel tank vent valve and replace if necessary to prevent over-pressurization.
