P1180 Code - Fuel Delivery System Malfunction Low
Quick Answer
The Powertrain Control Module (PCM) receives Fuel Tank Pressure (FTP) information from the Natural Gas module (NG), which uses the information to infer Fuel Rail Pressure (FRP). Common causes include Restriction in the fuel line, Plugged fuel filter, Faulty Fuel Pressure Regulator. 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.
