Your TPS is not working correctly at all in either log.  Either it is wired wrong or it is faulty.  It is only showing either 1.6 or 4.6V - nothing in between.

Also there appears to be some other wiring issue as the 5V out sometimes spikes up to 5.5V and this upsets your MAP sensor.

Edit:  I just noticed your battery voltage drops to 7V in the same areas the 5V spikes so you definitely have a big wiring problem by the looks.
