Common OBDII codes after swap

Most all common codes that pop up with OBDII will pop up wherever the system is. It does not matter that it has been swapped into something else. Unless of course, something got damaged or left disconnected during the swap.

Some of the hot codes I see at work include the following.

O2 codes. Pick one.

P0300 codes. Again, pick one.

300 is random misfire.

301 is cylinder one. 302 is cylinder two and so on.

Mass air codes.

MAP codes.

EVAP codes. This may or may not be relevant depending on how far you went with your swap.

Temp sensor codes.

These are about the most common in this area. I don't know the individual codes off the top of my head. Each problem has more than one code. Some have several.

But for the most part, as I said, it does not matter what vehicle the system is in as to what's more popular for codes.
