Multi malfunction sensor lifetime?

[Henrys]

i found a way to make them last longer.

i bought a spare 3 years ago when it looked like the old one was getting
intermittent.  found the rubber boot full of coolant, so i pulled it back
from the connector to drain and left it alone.  continues to work today and
the spare sits in a box.

It seems like it could be, yes.  Although, the new one I threw on my 90Q
seems to be holding up.  of course, I don't know about the A/C senders
on it since I tore that out...

But, hey, $40 a year?  A cup of coffee every other week?  Just pick one
up with every third or fourth oil filter...
