If you've only got 2 sensors and you aren't even reading from one of them then "bad" input is hard to know. You can do nothing if they both disagree but you can't actually know which sensor is bad and which is good without a tie breaker.

You don't need to automatically fix the disagreement. You just need to stop taking nose-down action and inform the human in charge .

Problem is, if you need to inform the human, you also need to train the human, which leads to extra costs.

Who knows but it the chatter makes it sound like the system doesn't have redundant sensors. You have two systems with one sensor each. One system is active and the other is inactive. And no voting logic.
