P144A Mercury Code - Evaporative Emission System Purge Vapor Line Restricted/Blocked
Quick Answer
The Powertrain Control Module (PCM) monitors the Evaporative Emission (EVAP) system for a blocked fuel vapor tube between the Fuel Tank Pressure (FTP) sensor and the fuel tank. Common causes include Faulty Evaporative Emission System Purge Valve, Evaporative Emission System Purge Valve harness is open or shorted, Evaporative Emission System Purge Valve circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
