Please someone who can help me with this waste of truck that are just problems, I already changed the ambient temperature sensor, the mass air sensor and the brake pedal sensor and it continues to give the same problem, the truck is in limp mode

It's probably in the wiring, if replacing the sensors didn't work.
Did you clear the codes, or did you just expect them to clear on their own? If you cleared them, then took key out (not always necessary but maybe) and then back to on, then rescan that may get the job done.
Electrical devices always require a complete circuit with correct voltages and appropriate ground. The codes you receive say the voltage is high, likely a short to voltage. There is no single common wire, but all connect to the ECM.

Since there is no faulty cable or sensor, I'm going to think it would be the ecm, I've seen some places that sell programmed ecms, is it safe to buy the ECM?
How did you determine there isn't a short in the wiring?
By all means then get a new ECM then, but I wouldn't do it without at least ohming out the wires. I'm to cheap to throw parts at a vehicle without doing my best to make sure they are faulty.
Mice can destroy a wire harness very quickly. Could also be a common splice point for all these circuits is corroded. Could also be a bad ground point if they all share the same ground.
Maf connector pin A 0 volt, pin B 12.68 volt, pin C 5.3 volt, pin D 5.3 volt. Pin E 0 volt
I have changed all the supposedly defective sensors and it continues to throw the same codes
