DRIVING HOME FROM WORK TRUCK QUITS PULLED CODE WITH FLASH TUNER CPS ERROR CODE SO I CHANGED IT. DROVE IT TO WORK NEXT DAY SAME THING BUT WHEN COOLED OFF FOR A WHILE STARTED BACK UP WILL RUN FOR ABOUT 15 MINUTES AND WILL QUITE. FLASH TUNER SHOWS CPS ERROR CODE AND THEN SHOWS PCM KEEP ALIVE MESSAGE. PUT ANOTHER CPS JUST SAFE MEASURE AND SAME HAPPENS. ANY IDEAS 2002 F250 7.3.

 

Put the first one you had back in and see if it works... or the second one. Might be the computer...
