P0255 code definition

The P0255 OBD-II Trouble Code refers to a problem with the injection pump fuel metering control “A” intermittent (cam/rotor/injector).

What the P0255 code means

The powertrain control module has found an issue with the signal voltage that is being supplied to the electronic fuel control actuator and the signal that’s being returned from the fuel metering control sensor. Only diesel vehicles will experience this code. If the code happens to show up in a vehicle that is not diesel, then the problem is a defective powertrain control module in most cases. In those instances, it shouldn’t affect the performance of the vehicle. On diesels though, the code could indicate some larger problems.

What causes the P0255 code?

A number of different things can cause the P0255 code to appear. The following are the most common causes:

  • Dirty fuel filter
  • Clogged fuel filter
  • Defective fuel pump
  • Shorted or open circuits
  • Shorted or open electrical connectors
  • Faulty fuel control actuator driver in the powertrain control module

What are the symptoms of the P0255 code?

The symptoms when this code appears can be very varied. In some cases, the driver might not actually notice any issues with their vehicle. However, in other cases, the vehicle might be very difficult to start, or it might not start at all. You might also notice misfires with the engine, hesitation with the engine, which is worse when you try to accelerate, and an increased amount of smoke coming from the exhaust.

How does a mechanic diagnose the P0255 code?

When the P0255 code appears, the mechanic will use an OBD-II scanner. This device attaches to the vehicle’s onboard computer. It then gathers data about the vehicle, including the code, or codes, that appear. Once they get the data, they will reset the code and take the vehicle for a drive to see if the code comes back or not. If it does come back, they will need to begin looking for the problem. They will generally start by looking for any obviously damaged components in the vehicle. They will look for things such as corroded wires or electrical components.

Common mistakes when diagnosing the P0255 code

Many times, the injector pump or the injectors are replaced when the code is present, even though they do not need to be. Most of the time, it is actually the fuel filter that is the problem. Other issues that are common include shorted or open wiring or connectors rather than a problem with the fuel pump.

How serious is the P0255 code?

Any type of trouble code means you should take the vehicle to a mechanic for a proper diagnosis. With this code, even though you might not notice any issues with the vehicle right away, they could still show up. You could have trouble with the engine starting as well as problems accelerating after you get it going.

What repairs can fix the P0255 code?

The following are some of the common repairs for the P0255 code:

  • Check the vehicle with the OBD-II device
  • Reset the code and test the vehicle to see if it comes back
  • Check the electrical connections for corrosion and other issues
  • Replace the fuel filter
  • Replace the fuel pump
  • Replace the fuel control actuator driver in the powertrain control module

Additional comments for consideration regarding the P0255 code

Keep in mind that this code will generally only appear on diesel vehicles. When the P0255 code appears, don’t dismiss it just because you have an older vehicle. Even though vehicles with more than 100,000 miles on them may have sensor issues and false trouble codes, there could still be a problem with the vehicle. The best thing to do is to speak with a mechanic who can examine the vehicle and determine what the real problem is, and then make the needed repairs.
