What does the code P0089 mean?
Fuel Pressure Regulator Performance
Diagnostic trouble code (DTC) P0089 stands for “Fuel Pressure Regulator Performance.” This trouble code sets when the powertrain control module (PCM) has determined that the desired and the actual fuel pressures do not correlate.
What is a fuel pressure sensor?
The fuel tank pressure sensor is part of the fuel pump assembly and is mounted on top of the tank or inside the tank. It’s part of the evaporative emissions system (commonly referred to as “EVAP”) and reads pressure in the fuel system to detect evaporative leaks, such as a loose or faulty gas cap.
What happens when pressure sensor fails?
The fuel pressure sensor is one of these sensors, and if it fails then it can significantly decrease your car’s ability to supply its engine with the right amount of fuel. This can lead to symptoms like weak acceleration, difficulty starting the car, stalling, and poor fuel economy.
Can you clean fuel pressure regulator?
Do not use compressed air to clean a fuel pressure regulator. If necessary, clean the fuel pressure regulators screen. If the fuel pressure regulator is immersed in a solvent bath, it will be damaged. The pressure regulator should be replaced if the filter screen is contaminated.
How do I know if my fuel pressure regulator is bad?

- Excessive fuel pump noise.
Where is the fuel tank sensor located?
What causes the p0089 trouble code on a Ford Explorer?
Potential causes of a P0089 trouble code may include: Possible Solutions. Fuel pressure – Fuel pressure can be checked by using a mechanical gauge attached to the fuel rail. If the fuel pressure is within factory specificaions, there may be a fault with the fuel pressure sensor giving false readings to the PCM/ECM.
What does the fuel rail pressure sensor do on a Renault?
P0089 Renault Description The Engine Control Module (ECM) uses commanded fuel pump flow to determine a desired fuel rail pressure. The actual fuel pressure is monitored using the Fuel Rail Pressure (FRP) Sensor.
What to do if you have a p0089 DTC code?
If there are any other codes such as Lean o2 sensors present along with the P0089, the P0089 code should be solved first before proceeding with other codes. Related fuel pressure regulator engine codes: Symptoms of a P0089 DTC may include:
