Code P1450 Mercury Description

The Powertrain Control Module (PCM) Monitors the fuel vapor vacuum and pressure in the fuel tank. System failure occurs when the Evaporative Emission (EVAP) running loss monitor detects excessive fuel tank vacuum with the engine running, but not at idle. The Diagnostic Trouble Code (DTC) will be set when the Powertrain Control Module running system monitors and detects excessive vacuum in the fuel tank/EVAP system.
