Voltaje range 5 to 20on Mabook air A2337 820-02016-A

Good days guys, I have a Macbook air M1 (820-02016-A) the fact is that when I connect it to the fuene the voltage ranges from 5 to 20 Volt and restarts again to 0 goes to 5 and 20 and so on, I have reviewed the values and the only one that gives me a little out of the ordinary is the PP1v25_S2 which should be 0.490 and is in 0.290 all others seem to be correct I have changed the usb C chip and I have programmed it and nothing remains the same, I need help

Hello Good morning and thanks for replay, i star back again to work in this board because i have so mucho to do, i finally i find a short but is a 25 volt line and go direct to the M1 processor, the line is PP1V06_S2SW_DRAM, you can tell me it is possible to inject voltage to see what component is to ground

Good Afternoon PPBUS_AON It is not stable, it varies from 6 to 12 to 19 and falls again and thus does the same cycle all the time.
