Code P1188 KIA Description
The Engine Control Module (ECM) determines the rail pressure value as a function of the engine’s operating conditions and controls the fuel pressure regulator to ensure that the rail pressure reaches the required value.
Fuel pressure in the fuel line including the pumps and injector are continuously monitored during engine running.
If the rail pressure is excessive, the fuel pressure regulator opens and a portion of the fuel is returned from the rail to the fuel tank via a collector line. If the rail pressure is too low, the fuel pressure regulator closes.
The fuel pressure regulator closes. the fuel pressure regulator is installed in the tail end of high pressure accumulator.
In case of the insufficient fuel supply in the fuel line, the engine symptoms will occur a shut down and a starting impossible.
If the fuel pressure monitoring in engine fuel pressure line generates threshold value, the ECM judged this as a fault and the P1188 code is set.
