The automobile fault code P1186 indicates a problem with the fuel pressure in the engine. The most common symptom is the Engine Light being ON or the Service Engine Soon Warning Light.
The cause of this fault code can be a faulty Fuel Pressure Regulator Valve (FPRV) stuck open, a faulty Fuel Rail Pressure Sensor (RPS), an open or shorted Fuel Rail Pressure Sensor harness, or a poor electrical connection in the Fuel Rail Pressure Sensor circuit.
To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion. Additionally, look for any broken, bent, pushed out, or corroded pins in the connectors. The repair time for this issue is estimated to be around 1.0 hour.
To interpret the fault code, you can refer to the “Possible Causes” listed above and perform the necessary inspections and repairs.

P1186 Fault Code: Understanding The Description And Troubleshooting Steps
The P1186 fault code is related to the fuel pressure in a standard rail diesel engine. The Engine Control Module (ECM) monitors the input rail pressure sensor signal to control the Fuel Pressure Regulator Valve. This valve helps maintain the optimum rail pressure based on the engine’s current rpm and load.
However, if there is a problem that causes the rail pressure to deviate from the target value set by the ECM, the engine will be shut down, and the P1186 fault code will be set.
This code indicates a “Fuel Pressure Monitoring-Minimum Pressure at Engine Speed Too Low” issue. It can be caused by low-pressure fuel supply, mechanical issues with the high-pressure pump, or problems with the Rail Pressure Sensor (RPS) output voltage and duty.
FAQ
If you’re seeing the engine light on or the service engine soon warning light, the fault code P1186 could be the culprit. This code is often caused by a faulty fuel pressure regulator valve (FPRV) stuck open, a faulty fuel rail pressure sensor (RPS), an open or shorted fuel rail pressure sensor harness, or a poor electrical connection in the fuel rail pressure sensor circuit. To fix this issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
If you’re dealing with the P1186 fault code and notice that your engine light is on, it’s time to take action. The possible causes for this code include a faulty fuel pressure regulator valve, a faulty fuel rail pressure sensor, an open or shorted fuel rail pressure sensor harness, or a poor electrical connection in the fuel rail pressure sensor circuit. To fix this issue, start by visually inspecting the wiring harness and connectors. Look for any signs of damage, such as broken or bent pins, corrosion, or components that are out of place. This step will help you identify any issues that need to be addressed.
When resolving the P1186 fault code, start by checking for damaged components or corroded connector pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any broken, bent, pushed out, or corroded pins on the connectors. By addressing these issues, you can effectively fix the problem and clear the Engine Light or Service Engine Soon Warning Light.
Wrap Up
If your engine light is on and you’re dealing with a P1186 fault code, it could be due to a faulty Fuel Pressure Regulator Valve (FPRV) stuck open, a faulty Fuel Rail Pressure Sensor (RPS), an open or shorted Fuel Rail Pressure Sensor harness, or a poor electrical connection in the Fuel Rail Pressure Sensor circuit. To fix this issue, visually inspect the wiring harness and connectors, check for damaged components, and look for any broken, bent, pushed out, or corroded connector pins.
