Read code 542, Fuel pump secondary circuit failure,PCM to ground. What does this mean

[1TRIKGT]

Just like the title says, I manually read my codes just now and the code 542-Fuel pump secondary circuit failure,PCM to ground comes up but what and where is the PCM, so I can fix the ground?
Thanx, Jose

Is the car running fine or is it having problems????

reset the computer, and see if it comes back. That code is sometimes refered to a "ghost code", as in there is no problem but the code will be generated from a momentary open circuit somewhere in the fuel pump wiring/unit.

yeah, my car runs great, but since i bought it throws that code....strange. No c-e light, just the code is stored
