P0450 Code - Evaporative Emission Control System Pressure Sensor Malfunction
Quick Answer
The Evaporative Emission System (EVAP) control system pressure sensor detects pressure in the purge line. Common causes include Faulty Evaporative Emission System (EVAP) Pressure sensor, Evaporative Emission System Pressure sensor harness is open or shorted, Evaporative Emission System Pressure sensor circuit poor electrical connection. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.
