P1189 Fault Code: Understanding The Description And Troubleshooting Tips
The P1189 fault code relates to fuel pressure monitoring in the high-pressure system of the automobile.
The Engine Control Module (ECM) determines the rail pressure based on the engine’s operating conditions and controls the fuel pressure regulator to ensure it reaches the required value. The fuel pressure in the fuel line, including the pumps and injectors, is continuously monitored while the engine is running.
If the rail pressure is excessive, the fuel pressure regulator opens, allowing some fuel to return to the fuel tank.
Conversely, if the rail pressure is too low, the fuel pressure regulator closes. The P1189 code is set when the ECM detects a deviation in the governor at high engine speeds, indicating a fault in the fuel pressure monitoring system.
This can lead to engine shutdown and difficulty starting the vehicle.
