My poorly educated guess is it may be an oil sensor.
I suspect that'll be the knock sensor.

If you remove it, you will need to do it up to the correct torque (with a small torque wrench) as if it is too tight it will sense normal engine running as 'knock' all the time - as I discovered when I was much younger!
