hi all have a question about my 94 f150 at 4x4 with 302............

i am getting codes 63 tps below min volts and 53 tps above max volts, but when i backprobe the wiring the closed and wot voltages match right up the the specs. any idea why it would still throw these codes? also, got my alternator rebuilt but its throwing codes for charging system above and below voltage, and is showing this on the charging gauge too need to take back to rebuilder but can this cause tps issue as well?

THANKS!
