undocumented oil temp sender in 88 YJ
replacing the Oil pressure sender the other day, I noticed what appears
to be a oil temp sensor just below it, on the same plumbing. Is this
some undocumented (it's not in either Haynes or Chiltons that I can
find) computer sensor or a non-working low oil level sensor I didn't
know YJ's had? Unplugging it does nothing, and My Jeeps been low enough
on Oil to have made itself known to me by now.

Re: undocumented oil temp sender in 88 YJ
That is the oil pressure safety switch used on the choke and manifold
heating element. It makes sure you can't burn out either one by leaving
the key in run with the engine not started. No oil pressure, no choke.
The engine should run like a pig and totally choke out with that
disconnected. The choke needs power to open.

Interesting, thanks Mike. BTW it wont run like a pig without it because
that computer and Carter BBD are no longer part of my YJ's engine.

It's undocumented but D-C is advocating amnesty.
