Sensor output voltage reading high

I have a an electrical problem that causes 4 sensors to show up as bad. I pulled codes for TP, IAT, ECT, and MAP. I measured the voltage on the harness side of the IAT (2 wire) and it read 30V. I thought that was weird since it should be no more than 5V. Then, I measured 5V between G/O wire and ground. What's going on here? Am I doing something wrong?

I actually found another thread similar to mine that Nico replied in but all that guy did was replace the ecu. I already replaced the ecu and nothing changed.

Anyone have some advice? There has to be something wrong with the power or ground. I replaced one of the bad sensors and code is still there. I checked the yellow box and it's clean, no burnt wires.
