Thank you much for being such a willing guinea pig!
I sent a draft response to Max, for his input.
Meanwhile, please probe the black/green wire at the TPS connector (unplugged would be best) and read resistance to battery negative post.
I'd expect <0.1 ohm
As for sensor readings, when unplugged, without removing the TPS:
Looking at the disconnected sensor, with locking tab up:
Left: black/yellow 5 VDC power
Center: black/red signal output (resistance between this and black/green ground should be 1.5 K ohms to 0.5 K ohms...open and close throttle while ohmmeter connected...using your third hand!) Based upon your black/red signal readings, I'd expect you to see these resistance values, with a smooth change as throttle moves. This is an alternate to the output signal test of 0.5 to 4.5 VDC.
Right: black/green ground
