What is the Fuel Pressure Sensor all about?

In fuel-injected and diesel engines, fuel rail pressure sensors monitor the pressure in the fuel rail and report the reading to the engine control module. If any drop in pressure is detected, the engine control module compensates so that the fuel pump can restore the proper pressure. A valve controls this pressure; if the sensor ever fails, you should replace it. Sometimes, the entire fuel rail may need to be replaced, but the sensor is a weak point in the loop that is more prone to damage.

If the sensor is working properly, only the amount of fuel that is needed to make the engine run properly will be delivered. Minimal excess fuel will be circulated back to the tank in the fuel return line.

Keep in mind:

Other problems such as a faulty crank position sensor, cam position sensor, air flow sensor, boost pressure sensor, and temperature sensor can mimic symptoms of a bad fuel rail sensor.
Starting problems may have myriad causes that are entirely unrelated to sensors.

How it's done:

The fuel pressure is bled and battery is disconnected
The defective fuel rail sensor is removed
The new fuel rail sensor is installed
The battery is reconnected
The repair is verified and the vehicle road tested for proper operation

Our recommendation:

The fuel rail sensor is not part of a maintenance check, and is only addressed when it fails. If you suspect a problem with your fuel rail sensor or fuel delivery system, have one of our expert mechanics inspect and replace the fuel rail sensor if necessary.

What common symptoms indicate you may need to replace the Fuel Pressure Sensor?

Car won’t start
Car runs erratically
Check Engine light comes on and stays on

How important is this service?

If your fuel rail sensor is faulty, you may experience difficulty starting the engine or poor performance that could cause trouble in traffic. Have a failed fuel rail sensor replaced as soon as possible.

I was pleasantly surprised Ian was early. I found him courteous, engaging, knowledgeable, patient and friendly. He completed his work in a very timely fashion. I was VERY happy with the results of his work. I appreciated his candor and explanation of what he did and what he found during courtesy inspection. "Thank you Ian". I would recommend Ian without reservation.

Lexus LS400 V8-4.0L - Car is stalling - Alameda, California

the problem with my car was intermittent so the first mechanic could not find any codes and could not diagnose the problem for why my car would stall during idle sometimes. Someone online mentioned it could be a dirty fuel filter so I just went ahead and booked an appointment for that, but when Tien got here, the check engine light was on and the car wouldn't start. He was able to get the codes and fix my starting problem, he figured out exactly what was wrong with my car and explained everything for me. He spend a lot of time diagnosing the problem and did not replace the fuel filter because he identified other issues. He was very honest and so hard working. I booked him for my next appointment and am so thankful for this website! Thank you Yourmechanic.com!!!
