P1185 KIA Code - Fuel Pressure Monitoring-Maximum Pressure Exceeded
Quick Answer
As input rail pressure sensor signal, the Engine Control Module (ECM) of the standard rail diesel engine controls Fuel Pressure Regulator Valve (integrated with a high-pressure pump) to maintain optimum rail pressure according to current engine rpm and load. Common causes include Faulty Fuel Pressure Regulator Valve (FPRV) stuck open, Faulty Fuel Rail Pressure Sensor (RPS), Fuel Rail Pressure Sensor harness is open or shorted. 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.
