The infamous multi-function sensor. BTDT, twice, once on each car.
It's on the upper coolant hose inlet to the head, has 3 or 4 pins.
Pull the boot to check the contact first, sometimes it's just loose
or corroded. If not, replace it. About $50, 2 minutes work.

Nope. That's usually low pentosin. I have a s-l-o-w leak from the bottle,
and every 2 months or so, my pentosin has dropped to the "low" mark,
making the light flicker on now and again, usually when driving, uh,
spirited.
