Order of inspection
P0453 Evaporative Emission Control System Pressure Sensor/Switch High Input Low
The P0453 code means the sensor that measures pressure inside the vapor system is reporting a voltage above the maximum. It is usually an open circuit or a corroded connector. It does not affect the engine, but it keeps the leak test from running and with it the emissions inspection.
