- Failed fuel pump replaced.
What does P0089 code 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 are the symptoms of a stuck fuel pressure regulator?
Symptoms Of A Bad Fuel Regulator
- Engine misfires/poor acceleration.
- Black smoke coming from the exhaust.
- Spark plugs appear black.
- Reduced fuel mileage.
- Gasoline in the vacuum hose.
- Engine backfires.
- Engine won’t crank.
- Excessive fuel pump noise.
How much is fuel pressure regulator?
The average cost to replace a fuel pressure regulator will be anywhere from $140 to $380 total. The parts cost alone will be anywhere from $60 to $240 while the labor costs will likely be around $80 to $140.
What does the fuel rail pressure sensor do?
It is a part of vehicle’s fuel system and designed to monitor the fuel pressure that is present at the fuel rail. The sensor sends this signal to the computer, which then uses it to make adjustments to the vehicle’s fuel and timing. When the sensor has an issue it can cause problems with the performance of the vehicle.
How do I know if my fuel pressure regulator is stuck open?
If a fuel pressure regulator is stuck open, it will build up more pressure than it should. This will cause the fuel injectors to inject more gas into the cylinders, resulting in a rich air/fuel mixture.
What happens if a fuel pressure regulator goes bad?
A faulty fuel pressure regulator can cause a loss of fuel pressure. As a result, the engine may exhibit performance problems, such as hard-starting, rough running, stalling, and a lack of power.
What are symptoms of a faulty fuel pressure regulator?
Usually, the following symptoms indicate a faulty fuel pressure regulator.
- Engine Misfires and Decrease in Power, Fuel Efficiency and Acceleration.
- Fuel Leaks.
- Black Smoke Emitting From the Exhaust.
- The Smell of Fuel from the Dipstick.
- Engine Malfunction.
- Noisy Fuel Pump.

Can I drive with a faulty fuel pressure sensor?
Can I drive with a faulty fuel pressure sensor? The simple answer is yes; you can still drive a car with a bad fuel pressure sensor if the problem isn’t too serious. But if it malfunctions in the long run, your car’s capacity to provide the engine with the proper amount of fuel will be greatly reduced.
What happens when a fuel 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.
What happens when a fuel regulator goes bad?
How do I know if my fuel pressure sensor is bad?
Here are the symptoms of a bad fuel pressure sensor that you should look out for:
- Trouble Starting Your Car.
- Stalling.
- Poor Acceleration.
- Poor Fuel Economy.
- Check Engine Light Is On.
What causes a fuel pressure regulator to fail?

Can a car run without a fuel pressure regulator?
Without the fuel pressure regulator, the fuel will go straight through your car’s system and never reach the injectors. If the fuel tank pass-through is blocked completely, too much fuel will be forced into the fuel injectors and cause them to fail.
Can a fuel pressure sensor be cleaned?
Can you clean fuel rail pressure sensor? You can clean the sensor, but it is doubtful that it will make a difference. In some very rare cases, dirt can block the passage to the sensor head, which will make the sensor work again after a clean. However, in most cases, you need to replace the fuel pressure sensor.
How do I know if my fuel pressure regulator is clogged?
6 Symptoms of a Bad Fuel Pressure Regulator (and Replacement Cost…
- #1 – Engine Misfires / Weak Acceleration.
- #2 – Spark Plugs Covered in Soot.
- #3 – Black Smoke.
- #4 – Fuel Dripping Out of Exhaust.
- #5 – Vacuum Hose Has Gasoline.
- #6 – Engine Won’t Turn Over.

How do I know if my fuel tank pressure sensor is bad?
If the vehicle is continually hard to start, the fuel tank pressure sensor may be the cause because it has direct input to the air to fuel ratio. If the vehicle is stalling suddenly, the cause may be a faulty fuel tank pressure sensor.
What will a bad fuel pressure regulator do?
