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.

Mitsubishi Lancer L4-2.0L - Car is not starting - Antelope, California
Jeff was great. He came out and inspected my car. I thought the starter was going out but he said it was the battery. He came back and fixed it in about 20 minutes. He was great. I am planning on giving out his card to family and friends.

Mitsubishi Diamante V6-3.5L - Serpentine/Drive Belt - Olathe, Kansas
Had a few appointments with David now, all of which went well. Friendly yet professional; gets the job done. Shows up on time and even offered to come early for one appointment--a stark contrast to another mechanic who completely blew off an appointment I had booked.

Mitsubishi Eclipse V6-3.8L - Cooling System Flush - Modesto, California
Carlos was a big help. He did the best he could with what he had. I messed up by putting gasket sealer in the radiator, but he flushed it as much as possible and bled the system of air. Put new coolant and the car is running cool now, even in 100 degree heat.
