P1188 Fault Code: Understanding The Description And Troubleshooting Tips
The P1188 fault code is related to fuel pressure monitoring in the high-pressure system of an automobile.
This monitoring system is designed to detect any issues or fuel leakage in the system.
The Engine Control Module (ECM) plays a crucial role in determining the rail pressure value based on the engine’s operating conditions. It also controls the fuel pressure regulator to ensure that the rail pressure reaches the required level. During engine running, the fuel pressure in the fuel line, including the pumps and injectors, is continuously monitored.
If the rail pressure becomes excessive, the fuel pressure regulator opens, allowing a portion of the fuel to be returned to the fuel tank via a collector line. On the other hand, if the rail pressure is too low, the fuel pressure regulator closes. The fuel pressure regulator is installed at the tail end of the high-pressure accumulator.
In case of insufficient fuel supply in the fuel line, this can lead to engine symptoms such as a shutdown and difficulty in starting the engine. When the ECM detects a threshold value in the fuel pressure monitoring system, it considers it a fault and sets the P1188 code, indicating a fuel pressure monitoring leakage issue.
