I wonder if TPS1 might be a throttle position sensor. If so, I am guessing that the sensor is going bad. I got a similar error when my trim sensor went bad. It told me that a sensor power supply voltage was low. Just a thought.
 
I think Jshell hit the nail on the head. 5 vdc is discrete voltage from sensor to computer, if the sensor is bad, or the connection has corrosion that would cause low voltage. Both engines doing the same thing is odd though, look for the common denominator...smart craft issue?
