About the F-150
The Ford F-150 first made its debut under the F-Series in 1975. This has made it one of the oldest pickup truck models on the market today. The F-Series has also been the best-selling pickup truck range in the United States since 1977.
The F-150 model entered its ninth generation in 2021, while the F-Series as a whole is currently in its fourteenth generation.
Among the most common codes that the F-150 is known to suffer, P0420 comes up the most often. This code indicates that the catalytic converter is not functioning properly. This code is specific to the catalytic converter in the first bank of the exhaust.
With older models, it can become quite likely that the catalytic converter is beginning to fail and needs replacing. In other cases, it is a good idea to look for faulty oxygen sensors or leaks in the exhaust.
Another common problem for the F-150 is that it can run lean. This is shown by both fault codes P0171 and P0174 being logged. These two codes indicate that the first and second banks are at fault respectively.
If both of these codes are logged simultaneously, it is likely that there is an upstream issue in either the air or fuel supply systems. This can include low fuel pressure, vacuum leaks, and a long list of other issues that owners have reported.
