02 4.2L v6 error codes
My son picked up a 02 F 150 4.2L v6 4x4 and it runs fine has no issues running but the check engine light is on. He took it in to the local part shop and they gave him the error codes.
P0174
P1401
P1451
P2151
Anyone know where I can find what these mean?
thanks

Since you got the truck with the codes, I would clear them and see what comes back because this is 'old' history as far as your concerned.
Then address those that return.
The list given implicates 4 different problem areas.
A lean indication on bank 2.
An evap issue, a fuel system issue and an EGR issue.
Not sure you really have all these until you clear and let the system retest everything over several drive cycles.
All you need to do is remove the Plus battery cable for a few minutes then re connect.
This causes a complete reboot and test of all systems over a number of drive cycles.
The EVAP system takes a long time and may not clear if there is an issue.
A clear done with a reader or scanner only causes a retest but not a reboot, to take place. Either way is ok.
Expect anything on a 02 used vehichle.
A reader is cheap these days.
Good luck.

These webpages tell what each of these codes mean and possible causes. I hope this helps.

Here is all I could find on P1401:

All I could find is a description of P2151:
P2151 Fuel Injector Group "B" Supply Voltage Circuit High
