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.

What are the possible causes of the automobile fault code P1189 and how can I visually inspect them?

If you’re seeing the engine light on or the service engine soon warning light, the fault code P1189 could be the culprit. This code can be caused by a faulty fuel filter, injector, electric fuel pump, fuel pressure regulator (FPR), rail pressure sensor (RPS), or even the engine control module (ECM). To visually inspect these possible causes, check the related wiring harness and connectors for any damage. Look out for broken, bent, pushed out, or corroded connector pins as well. Take a close look to identify any issues and proceed with the necessary fixes.

How can a faulty fuel filter, injector, electric fuel pump, fuel pressure regulator, rail pressure sensor, or engine control module trigger the P1189 fault code?

If you’re experiencing the dreaded P1189 fault code with your engine light on, it could be due to a faulty fuel filter, injector, electric fuel pump, fuel pressure regulator, rail pressure sensor, or engine control module. To fix this issue, start by checking the possible causes mentioned above. Take a close look at the wiring harness and connectors, ensuring there are no visible damages. Additionally, inspect the components for any signs of breakage, bending, or corrosion on the connector’s pins.

What steps should I take to fix the P1189 fault code and ensure that the related wiring harness and connectors are in good condition?

To fix the P1189 fault code and ensure the wiring harness and connectors are in good condition, start by checking the possible causes: faulty fuel filter, injector, electric fuel pump, fuel pressure regulator (FPR), rail pressure sensor (RPS), or engine control module (ECM). Then, visually inspect the wiring harness and connectors, looking for any damaged components or broken, bent, pushed out, or corroded pins on the connectors.
