I think we don't use them enough.
About 2 months ago I started to get a low coolant warning, checked & rechecked and had plenty of fluid. Finally took it in for a few items and had them check that, ended up replacing that sensor. Just got it back and this past weekend I got a low oil level warning light that faintly was trying to come on.(full oil) It ended up going out within 20 minutes.
I think these things don't get used like their used to.
