It's worse than that. When they refitted the 737 with newer, larger engines to create the 737 Max there wasn't enough room, so they were shifted forwards (look at the pictures - the engines are almost in front of the wings). This created a setup where the thrust could make the plane pitch up in certain cituations - the system isn't in balance anymore. Thus the sensor to detect pitch-up and the software to try to compensate for that. A hack to fix a hack. The whole airplane should be redesigned to balance as an 'old' 737.
I for one won't set my feet in any 737 Max, whatever software or sensor upgrades they put in. No way.

- Tor3 8y agoPointing only at thrust is probably inaccurate, I agree. However, several sources point to the shifted center of gravity as a cause of the pitch, not just aerodynamic effects.
