I've done a fair bit of testing recently with cheap crap China sensors whether on oil or water injection.
Compared to better quality sensors on my car, the readings from them do seem a lot more erratic and require more filtering. But for non critical items ( and most only cost me £10ea ) that's of no real concern. Using them mostly for information so no harm can come if they do fail.

Someone I know has managed to fail a couple of them by supplying them with 12v instead of 5v because he didn't want to tap into a 5v rev and ground in his factory harness.
There are a few unused 5v and ground pins on the factory PCM connector that he could have easily tapped into. They did manage to last a few months on 12v.
