Something to lighten up our day...

On some manual transmission cars, there is a light that tells the
driver when to upshift to the next gear speed.

Where is the sensor for this operation, and what type sensor is it?
In your car (if you have one) is it in the transmission?  Connected to
the oil pressure? The Air intake? A Combination of these? Is it
analogue or digital?

The operation of this system in my car has been intermittent since I
purchased the car. It seems to correlate to a change or addition of
oil when it sometimes works for a few days when the engine has yet to
reach full operating temperature. I really don't need it, but it would
be nice to have it working if I sell the car.

I have intentionally omitted the type and year of my vehicle in order
to encourage a more general response.
