Ford F-250 Fault Codes

About the F-250

The Ford F-250 Super Duty was first released by Ford in 1999 under the F-Series Super Duty range. Since then, there have been a total of five generations under the Super Duty series, which starts with this model. The latest generation was released in 2023.

It is the smallest member of the series, as denoted by its name. However, it is larger than the F-150 found in the regular F-Series.

Being one of the best-selling heavy-duty pickup trucks, there is a lot of competition for the F-250. The most notable of these include the Chevrolet Silverado 2500, RAM Trucks 2500, and GMC Sierra 2500.

Among the most commonly searched codes for the model, P0088 is at the top. This code indicates that the fuel pressure is too high.

One of the most common causes of this fault code is a faulty fuel filter that is increasing the pressure in the system. Another fairly common cause is a faulty fuel pressure sensor, which can provide an incorrect reading, triggering the code. Issues in the sensor circuit can also be the culprit.

Fault code P0300 is another problem that owners have reported. This code indicates that random, multiple misfires have occurred.

The first step for this issue is typically replacing ignition coil packs to ensure there is proper ignition in the chambers. Some owners have reported that broken valve springs can also lead to this issue and are quite a common occurrence. Fuel injectors should also be checked as well.

Another problem that the F-250 has faced is P0401, which indicates that there is insufficient flow in the EGR system.

Owners have reported that a fouled EGR can be one of the most common causes of this issue. In some cases, the EGR valve will need to be replaced.
