A fuel rail pressure sensor (commonly known as a fuel pressure sensor) is used in many diesel and some gasoline engines. This sensor is usually located near the middle of the fuel rail and is linked to the engine control unit (ECU), which is the central computer of a vehicle.
How do I know if my fuel rail pressure sensor is bad?
- The engine does not start or has a difficult start. …
- Increased fuel consumption. …
- Check engine light is on. …
- Weak acceleration power. …
- Engine stalling. …
- You feel like you’ve lost a lot of engine power.
Can you drive with a bad fuel rail pressure sensor?
Can I Drive With a Bad Fuel Pressure Sensor? You can, in theory, as long as the issue isn’t too bad. If your fuel pressure sensor has just started to fail, you would probably still be able to drive your car to a repair shop without any problems.
How long does it take to replace a fuel rail pressure sensor?
A professional mechanic would require roughly 5 hours. (If just the regulator is replaced that takes about 1 hour).
What happens when the fuel tank pressure sensor goes bad?
Common reasons for failure:
Over time a faulty fuel tank pressure sensor will cause low fuel efficiency, trouble starting the vehicle and/or stalling, and eventually keep the vehicle from starting.
How much does it cost to replace a fuel rail pressure sensor?
The average cost for fuel pressure sensor replacement is between $252 and $282. Labor costs are estimated between $113 and $142 while parts are priced at $139. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location.

Can a car run without a fuel pressure sensor?
If the pressure switch is bad then the computer has no feed back to control fuel pressure and may go into failure mode. The failure mode can cause the engine to run erratic and the transmission to shift harsh, so this may be causing the problems you are having.
Where is the fuel sensor located in the car?
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’s a fuel rail pressure sensor?
The common rail pressure sensor is located on the fuel rail. Its function is to monitor the fuel pressure in the common rail. Sensor is used by the ECM as a part of the calculation for the % duty cycle applied to the Fuel Pressure Control Valve and Fuel Quantity Control Valve.

How many fuel sensors are in a car?
Your vehicle may have one, two, three or four sensors, depending on the engine type, make and model. You can tell your oxygen sensor is faulty by the following signs: Failure to pass the emissions test.
How long does a fuel pressure sensor last?
Just most of the sensors or switches on your vehicle, the fuel rail sensor is designed to last for the life of the vehicle. The sensor will usually need to be replaced due to wear on the terminals that it has.
Can you clean a fuel pressure sensor?
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 fix code P0191?
- Replacing the fuel pump.
- Replacing the fuel pressure regulator.
- Repairing any broken, frayed, or shorted wires that lead to the fuel pressure sensor.
- Repairing corroded connector to the fuel pressure sensor.
- Replacing fuel pressure sensor.
- Repairing any vacuum leaks in the engine.

What is normal fuel rail pressure?
No matter what operating condition (short of demanding more fuel than the pump can supply), pressure in the rail will always be 58psi (or pretty close).
Can a fuel rail go bad?
A faulty rail sensor may upset the air fuel ratio and cause the vehicle to experience performance issues such as a decrease in power, acceleration, and fuel efficiency, and in some cases may even experience stalling.
Is a fuel pressure regulator the same as a fuel pressure sensor?
The fuel pressure regulator has a convenient pressure port where a fuel pressure gauge can be attached. In some cases, a fuel pressure sensor is used in place of a fuel pressure gauge to provide digital output. … A larger fuel pressure regulator can take more flow and keep a higher pressure and maintain the 1:1 ratio.

How do I reset my fuel sensor?
- Turn your car’s ignition to the “on” position to turn its power on without turning the engine on.
- From there, press the odometer or trip meter button until the odometer is in “ODO” mode.
- Turn off the ignition.
- After that, press and then hold the odometer or trip button.
- Release the button.

How much does a fuel tank pressure sensor cost?
The average cost for a Fuel Tank Pressure Sensor Replacement is between $245 and $284 but can vary from car to car.
What causes pressure in a gas tank?
Vapor Pressure Builds From Heat
The gasses released from liquid gasoline in a sealed container (the gas tank) are directly affected by the temperature of the gasoline; the higher the temperature is, the more pressure builds in the container.
