How much is a fuel rail pressure sensor?
On average, you can expect to pay somewhere between $190 and $220 for fuel rail pressure sensor replacement in most cases. That will include a new fuel rail pressure sensor, which will run you about $100, and about $100 or so in labor costs.
What does a fuel rail pressure sensor do?
The fuel rail is responsible for the delivery of fuel to the combustion chamber. This sensor makes sure your car’s engine cylinders are getting the right amount of fuel at the right pressure.
What kind of pressure sensor does a diesel engine use?
A fuel rail pressure sensor (commonly known as a fuel pressure sensor) is used in many diesel and some gasoline engines.
Can a bad fuel rail sensor cause a stall?
Improper supply of fuel to the engine will cause an unexpected stall. No matter what you try, the engine will often not start again. If this happens frequently, the fuel rail pressure sensor might not be working properly enough to send the correct information to the vehicle’s onboard computer.
Why is my fuel pressure sensor too low?
P0191 Fuel Rail Pressure Performance; could be a bad rail pressure sensor or reporting that the rail pressure is too low. If the rail pressure sensor fails, the ECM will substitute a default value.
What are the symptoms of a bad fuel pressure sensor?
Another symptom of a possible issue with the injector control pressure sensor is engine performance issues. A faulty sensor can throw off the fuel mixture and cause the engine to experience misfires, a loss in power and acceleration, a loss in fuel economy, and in some cases even stalling.
What does a bad fuel pressure sensor do?
With a bad fuel pressure sensor, the engine will not receive the correct amount of fuel for its internal combustion process. Most of the time, too much fuel will be pumped into the combustion chamber and there will be a noticeable reduction in your MPG from running too rich.
What should the fuel pressure be at the fuel rail?
With a return system, the base pressure is set with the engine off, but the pump running. For a GM, this pressure is usually set to 58psi (factory fuel pressure in the rail).
What is the normal fuel pressure at the rail?
For a GM, this pressure is usually set to 58psi (factory fuel pressure in the rail). The vacuum/boost referenced regulator will help to change the pressure in the rail based on the pressure in the manifold. When an engine is idling, it may be pulling 20 inHg of vacuum, which translates to roughly 10psi.
