if you earth the sender wire the gauge needle should read max temp

If you have an ohm meter. Measure the resistance across the sender. It should change as the temp changes.
It will tell you the sender is working, but not exactly if its still accurate.
You would need the workshop manual to determine resistance at different temps.

Might just be a loose connection. Check that out too.
